Durant cette période de confinement, les créatifs rivalisent d’ingéniosité pour rester créatifs et continuer leur pratique. C’est le cas du photographe Florian W.  Mueller. Contraint de rester chez lui avec son fils de 6 ans et donc dans l’impossibilité de voyager pour réaliser des projets, il a opté pour la création à domicile. Lorsque son […]

Summer is going to look a bit different in the Corridor this year as many, long-cherished events are being canceled or postponed. And the organizations that run those events want you to know they aren’t any more happy about it than you are.

The organizers of these events are having to make unprecedented, tough decisions.

“Cancellation is not a good word in our business,” said Chuck Swanson, Building a Legacy executive director of Hancher. “It is something that we really don’t want to do and it takes a lot for us to come to that.

“We live for the live performance and bringing the artists and audiences together. That’s the happiest time for me, so none of these decisions have been easy.”

Hancher has had to cancel numerous upcoming events in the past few months that would have brought to Iowa City in artists from all over the country and the world. It also is holding off announcing its upcoming season — which it typically would be doing at this time of year.

this isn’t something the staff has faced since the floods of 2008 and because they book events so far in advance they are confronting additional challenges.

“You know there’s so much that goes into a show before it happens,” Swanson said. “I just think of all the anticipation, booking the artists, advancing the show, setting ticket prices, advertising and then ticket sales.

“It’s like a farmer who does all this work to get his crops ready and then at the end of the season ends up with nothing to harvest.”

He noted Hancher has been reaching out to its booked performers and, in some cases, have had performers reach out to them to cancel upcoming shows.

The significant time and resources that go into planning large-scale events is the main factor in necessitating cancellation discussions and decisions at many organizations.

“Many logistical items have to be coordinated, from renting shuttles to scheduling volunteers and staff. Initial planning for some events begins as early as 12 to 18 months in advance and proceeds all the way up to the day of the event,” said John Myers, Indian Creek Nature Center executive director.

Citing the center’s annual Maple Syrup Festival, he noted food represents a significant cost and often cannot be saved or reused.

“We have had to be mindful of the financial resources available to us and ensure that we wisely manage those to ensure (the center) can emerge from this pandemic as a functioning and healthy organization,” he said.

“None of the decisions to cancel events or how to handle subsequent financial losses are easy and they challenge everyone,” Myers added. “As our whole lives have been upended, it makes even the simplest of decisions harder and that takes an impact on morale.”

He acknowledged staff members aren’t the only ones feeling the strain.

“We have a significant core of volunteers who are no longer able to give their time, which also creates a strain on morale and increases the amount of work that needs to be done when we return,” he pointed out.

Another primary factor is what is allowed and considered safe by the city, state and Iowa Department of Public Health.

“At this point, only allowing groups of 10 or less is a far cry from the thousands or people we usually see at the Iowa Arts Festival,” said Lisa Barnes, executive director of Summer of the Arts in Iowa City, which produces the Iowa Arts Festival.

“The governor has announced that reopening the state will be done in stages, and based on what we’ve found from other events around the country, concerts and large festivals will be the last to open,” he noted.

Summer of the Arts announced just last week that the Iowa Arts Festival would not take place this year, a month in advance of the event.

“We needed to make a decision so that we can move forward with alternative plans,” Barnes said, noting the organization has had questions about the Iowa City Jazz Festival, scheduled for July 3 through 5 and added a decision regarding that festival and July programming will be made by mid-late May.

“We also needed to make the decision far enough out to be able to work with our performers and cancel the agreements,” she said.

On Wednesday, Gov. Kim Reynolds loosened some but not all of the social-distancing restrictions for the remaining 22 counties she had put in place.

Discussions about the future of these events have been happening for weeks for many organizations, highlighting they are not taken lightly.

Carissa Johnson, executive director of the Cedar Rapids Freedom Festival, said conversations about the future of this year’s event started in mid-March, right around the time the Cedar Rapids SaPaDaPaSo Parade announced its cancellation for 2020.

“We plan year ’round for the two- to three-week festival,” Johnson explained.

“Our planning really ramps up in April and May, and we have many more costs associated with producing the festival the closer we get to the start. In order to protect our time and resources, we elected to cancel before we had more costs and variables to consider.”

As for who is making the final decision, organizations said many stakeholders are involved. Barnes said the decision on the Iowa City Arts Festival, for example, included staff, the board of directors, festival planning committees, the city of Iowa City and Johnson County Public Health, along with input from some of the vendors, artists and performers.

Tapping into experts in those public health field has been key as well.

“We have these assets, people, at the University (of Iowa), that have been really helpful as we make these decisions about canceling and as we prepare to think about reopening,” Hancher’s Swanson said.

The Freedom Festival include staff and board members in discussions, with recommendations from Linn County Public Health and the city of Cedar Rapids, factoring in the health, safety and well-being of the community.

“We are just as heartbroken as the rest of the community, but this decision was to protect our community as much as possible,” Swanson said.

“This community is a family and we will all get through this together and come back stronger next year.”

Myers noted organizations such as the Indian Creek Nature Center are also rely on advice from national associations, such as the American Alliance of Museums, and discussions among the leadership of many local cultural groups.

“For many events, we have also reached out to participants to gather their input and comfort level of attending once we are able to reopen,” Myers said.

The financial effects of having to cancel is stressful for organizations, too.

“Financially, this has been a hard time for the Nature Center to endure,” Myers pointed out. “We’ve had over 100 different programs, events and facility rentals canceled between March 15 and April 30, and our losses are currently over $250,000. As we approach the summer, there are a number of other events we continue to review, including our popular summer camps.”

The Nature Center has postponed a national conference to be held there in September — due to indications of low participation — for peers from around the nation who run not-for-profit and government nature centers.

“We are losing thousands of dollars in vendor fees and sales receipts because we had to cancel,” said Barnes, of Summer of the Arts.

“We have sponsors tied to certain events, like the Iowa Arts Festival, that in some cases want to carry over their support to next year, which impacts our fundraising for this year and next.”

She noted her group already has been made aware of funding that won’t be coming in from some sponsors next year due to the financial impact those organizations are facing as well.

And that can be tough.

“When we cancel, our whole staff is involved — from the box audience and public engagement folks to the technical production team and our front-of-house staff,” Swanson said.

“Our communication is key in talking through it all and then sharing clear messages with our audiences, especially in terms of refunds. But we’ve been encouraged by so many generous friends of Hancher donating their ticket purchase price back to us.”

While disappointment still is thick in the air, organizations don’t plan to abandon their missions and is keeping an eye on serving the public.

“This is a challenging time for everyone, and our board and staff is committed to finding creative and non-traditional solutions to ensure the Freedom Festival’s return,” Johnson said. “The community and our stakeholders have been tremendous supports of the Freedom Festival and we believe they will continue to do so in the future.

“We ask for understanding and patience as we try to navigate this crisis and what we can still provide for our community.”

Freedom Festival buttons will be sold this year as they’ve already been made, and “It’s a way the community can show their support,” Johnson said.

Barnes agreed and noted the Iowa Arts Festival committee is working on ways to support the performers, artists and vendors they had scheduled by trying to develop some virtual opportunities for engagement.

While the show, or events, might not go on, organizers said they very much want to remain connected to their audiences and attendees.

“I want to make sure everybody knows we care about them and that we’re trying to find ways to stay connected because I think we’re all in this together and the arts are one of the best ways for people to get through difficult times,” Swanson said.

Myers agreed.

“Indian Creek Nature Center will be ready to welcome guests and visitors back to our events as soon as we are able to do so safely,” he said.

“In the meantime, we hope everyone finds peace in nature by taking a hike or bike ride, having a picnic or just enjoying time outside.”

Iowa State University graduates who celebrated commencement Friday saw lots of caps and gowns, red-and-gold confetti and arenas packed with friends and family.

But none of those images were from this year — which now is defined by the novel coronavirus that has forced education online and put an end to large gatherings like graduation ceremonies.

Appearing in front of a red ISU screen Friday, College of Agriculture and Life Sciences Dean Daniel J. Robison addressed graduates like he usually would at commencement — but this time in a recorded message acknowledging the unprecedented circumstances keeping them apart.

“This year, because of the COVID crisis, we are unfortunately not all together for this happy occasion,” he said, pushing forward in a motivational tone by quoting famed ISU alumnus George Washington Carver.

“When you can do the common things in life in an uncommon way, you will command the attention of the world,” Robison said, citing Carver.

About 12,000 graduates across Iowa’s public universities this month are doing exactly that — capping their collegiate careers with never-before-attempted online-only commencement ceremonies, with each campus and their respective colleges attempting a variety of virtual celebration methods.

ISU and the University of Iowa are attempting some form of socially-distanced livestreamed convocation with countdown clocks and virtual confetti. All three campuses including the University of Northern Iowa have posted online recorded messages, videos and slides acknowledging individual graduates.

Some slides include photos, thank-yous, quotes and student plans for after graduation.

UNI, which didn’t try any form of a live virtual ceremony, instead created a graduation website that went live Thursday. That site hosts an array of recorded video messages — including one from UNI President Mark Nook who, standing alone behind a podium on campus clad in traditional academic regalia, recognized his campus’ 1,500-some spring graduates and their unusual challenges.

“We know the loss you feel in not being able to be on campus to celebrate this time with your friends, faculty and staff,” Nook said. “To walk around campus in your robe and to take those pictures with friends and family members … The loss is felt by many of us as well.”

He reminded those listening that this spring’s UNI graduates — like those at the UI and ISU — can participate in an upcoming in-person commencement ceremony.

And although students were allowed to return caps and gowns they ordered for their canceled walks across the stage, some kept them as keepsakes. The campuses offered other tokens of remembrance as well, including “CYlebration” gift packages ISU sent to graduates in April stuffed with a souvenir tassel, diploma cover, and streamer tube — to make up for the confetti that won’t be falling on graduation caps from the Hilton Coliseum rafters.

In addition to the recorded messages from 17 UI leaders — including President Bruce Harreld — the campus solicited parent messages, which will be included in the live virtual ceremonies.

To date, about 3,100 of the more than 5,400 UI graduates have RSVP’d to participate in the ceremony, which spokeswoman Anne Bassett said is a required affirmation from the students to have their names read.

“Students do not have to sign up to watch,” she said. “So there’s no way at this time to predict how many will do so.”

Despite the historic nature of the first online-only commencement ceremonies — forever bonding distanced graduates through the shared experience — UI graduate Omar Khodor, 22, said it’s a club he would have liked to avoid.

“I’d definitely prefer not to be part of that group,” the environmental science major said, sharing disappointment over the education, experiences and celebrations he lost to the pandemic.

“A lot of students like myself, we’re upset, but we’re not really allowed to be upset given the circumstances,” Khodor said. “You have this sense that something is unfair, that something has been taken from you. But you can’t be mad about it at all.”

Life is too short to dwell on what could have been or what should have been — which sort of captures graduate Dawn Hales’ motivation to get an ISU degree.

The 63-year-old Ames grandmother calls herself the “oldest BSN Iowa State grad ever.”

“It’s the truth, because we’re only the second cohort to graduate,” Hales said. “I’ll probably be the oldest for a while.”

ISU began offering a Bachelor of Science in nursing degree in fall 2018 for registered nurses hoping to advance their careers — like Hales, who spent years in nursing before becoming director of nursing at Accura Healthcare, a skilled nursing and rehabilitation center in Ames.

In addition to wanting more education, Hales said, she felt like the “odd man out” in her red-and-gold family — with her husband, three sons and their wives all earning ISU degrees. She earned an associate degree and became a registered nurse with community college training.

“I was director of nursing at different facilities, but I did not have a four-year degree,” she said. “I always wanted to get my BSN.”

So in January 2019, she started full-time toward her three-semester pursuit of a BSN — even as she continued working. And her education took a relevant and important turn when COVID-19 arrived.

“My capstone project was infection control,” she said, noting her focus later sharpened to “infection control and crisis management” — perfect timing to fight the coronavirus, which has hit long-term care facilities particularly hard.

“We were hyper vigilant,” Hales said of her facility, which has yet to report a case of COVID-19. “I think we were probably one of the first facilities that pretty much shut down and started assessing our staff when they would come in.”

Hales said she was eager to walk in her first university graduation and was planning antics for it with her 10-year-old granddaughter.

“We were trying to think, should I dance across the stage?” Hales said. “Or would I grab a walker and act like an old lady going across the stage?

“She was trying to teach me to do this ‘dab’ move,” Hales said. “I said, ‘Honey, I cannot figure that out.’”

In the end, Hales watched the celebration online instead. She did, however, get a personalized license plate that reads, “RN2BSN.”

Coming from a family-run dairy farm in Jerome, Idaho, EllieMae Millenkamp, 22, is the first in her family to graduate college.

Although music is her passion, Millenkamp long expected to study at an agriculture school — but Colorado State was her original choice.

Then, while visiting family in Iowa during a cousin’s visit to ISU, she fell in love with the Ames campus and recalibrated her academic path.

While at ISU, the musical Millenkamp began writing more songs and performing more online, which led to in-person shows and a local band.

And then, during her junior year, a talent scout reached out to invite her to participate in an audition for NBC’s “The Voice.” That went well and Millenkamp, in the summer before her senior year, moved to Los Angeles and made it onto the show.

She achieved second-round status before being bumped, but the experience offered her lifelong friendships and connections and invigorated her musical pursuits — which have been slowed by COVID-19. Shows have been canceled in now idled bars.

Millenkamp went back to Idaho to be with her family, like thousands of her peers also did with their families, when the ISU campus shut down.

After graduation she plans on returning and working the family farm again until her musical career has the chance to regain momentum.

But she recently returned to Ames for finals. And she and some friends, also in town, plan to celebrate graduation, even if not with an official cap and gown.

“We’ll probably have a bonfire and all hang out,” she said. “We’ll celebrate in our own way.”

Most college seniors nearing graduation get to spend their academic hours focusing on their major and interests, wrapping their four or sometimes five years with passion projects and capstone experiences.

That was Omar Khodor’s plan — with lab-based DNA sequencing on tap, along with a geology trip and policy proposal he planned to present to the Iowa Legislature. But all that got canceled — and even some requirements were waived since COVID-19 made them impossible.

“There were still a lot of a lot of things to wrap up,” he said. “A lot of things I was looking forward to.”

He’s ending the year with just three classes to finish and “absolutely” would have preferred to have a fuller plate.

But Khodor’s academic career isn’t over. He’s planning to attend law school in the fall at the University of Pennsylvania, where he’ll pursue environmental law. But this spring has diminished his enthusiasm, with the question lingering of whether in-person courses will return to campus soon.

If they don’t, he’s still leaning toward enrolling — in part — because of all the work that goes into applying and getting accepted, which he’s already done.

“But online classes are definitely less fulfilling, less motivating. You feel like you learn less,” he said. “So it will kind of be a tossup. There’ll be some trade-offs involved in what I would gain versus what I would be paying for such an expensive endeavor like law school.”

As for missing a traditional college commencement, Khodor said he will, even though he plans to participate in the virtual alternative.

“Before it got canceled, I didn’t think that I was looking forward to it as much as I actually was,” he said.

Not so much for the pomp and circumstance, but for the closure, which none of the seniors got this year. When the universities announced no one would return to campus this semester, students were away on spring break.

They had already experienced their last in-person class, their last after-class drink, their last cram session, their last study group, their last lecture, their last Iowa Memorial Union lunch — and they didn’t even know it.

“So many of us, we won’t have closure, and that can kind of be a difficult thing,” he said.

This image shows a particular optical illusion that confronts us every day. Notice the difference between the black text on a white background and the reverse. With reversed type — light text on a darker background — the strokes seem bolder.

Black text on white is very familiar, so we can be forgiven for thinking it correctly proportioned. For familiarity’s sake we can say it is, but there are two effects happening here: The white background bleeds over the black, making the strokes seem thinner. With reversed type the opposite is true: The white strokes bleed over the black, making it seem bolder.

One of the most obvious examples of this is with signs where the letters are punched into the surround then lit from inside. In his article, Designing the ultimate wayfinding typeface, Ralph Herrmann used his own Legibility Text Tool to simulate this effect for road and navigational signs.

One might say that characters are only correctly proportioned with low-contrast. Although objective reality hails that as true, it isn’t a good reason to always set type with low contrast. Type designers have invariably designed around optical illusions and the constraints of different media for us. Low-contrast text can also create legibility and accessibility problems. Fortunately, kind folks like Gez Lemon have provided us with simple tools to check.

As fascinating as optical illusions are —  the disturbing, impossible art of Escher comes to mind — we can design around reversed body type. On the Web, increasing tracking and leading are as simple as increasing the mis-named letter-spacing and line-height in CSS. However, decreasing font weight is a thornier problem. Yes, we will be able to use @font-face to select a variant with a lighter weight, but the core web fonts offer us no options, and there are only a few limited choices with system fonts like Helvetica Neue.

Reversing a logotype

For logotype there are plenty of options, but it makes me slightly uncomfortable to consider switching to a lighter font for reversed type logos. The typeface itself is not the logotype; the variant is, so switching font could be tricky. Ironically, I’d have to be very sure that that was no perceivable difference using a lighter weight font. Also, with display faces, there’s often not a lighter weight available — a problem I came across designing the Analog logo.

The logotype worked well when testing it in black on white. However, I wanted a reversed version, too. That’s when I noticed the impact of the optical illusion:

It looked bloated! Objective reality be damned; it simply wouldn’t do. After a few minutes contemplating the carnage of adjusting every control point by hand, I remembered something; eureka!

Punching the paths through a background image in Fireworks CS4 removed the illusion. (Select both the path and the background then using Modify > Combine Paths > Punch.) Is this a bug? I don’t know, but if it is, it’s a useful one for a change!

I grinned. I was happy. All was well with the world again. Lovely! Now I could go right ahead and think about colour and I wouldn’t be far from done. This is how it emerged:

A final note on logotype design & illusions

Before we even got to actual type for the Analog logo, we first had to distill what it would convey. In our case, Alan took us through a process to define the brand values and vision. What emerged were keywords and concepts that fed into the final design. The choice of type, colour, and setting were children of that process. Style is the offspring of meaning.

I always work in greyscale for the first iterations of a new logo for a few simple reasons:

1. The form has to work independently of colour — think printing in greyscale or having the logo viewed by people with a colour-impairment.
2. It allows for quick testing of various sizes — small, high contrast versions will emphasise rendering and legibility issues at screen resolutions, especially along curves.
3. I like black and white. :)

I realise that in this day and age the vast majority of logos need to perform primarily on the Web. However, call me old-fashioned, but I still think that they should work in black and white, too.

Brands and display faces emerged with consumer culture during the 19^th Century. Logotypes were displayed prominently in high streets, advertising hoardings, and on sign boards. In many instances the message would be in black and white. They were designed to be legible from a distance, at a glance, and to be instantly recognisable. Even with colour, contrast was important.

The same is true for the Web today; only the context has changed, and the popularity of logomarks and icons. We should always test any logo at low resolutions and sizes, and the brand must still have good contrast (regardless of WCAG 2.0) to be optimal. A combination of colour and form works wonders, but in a world of a million colours where only a handful are named in common parlance, having the right form still seems a smarter choice than trying to own a palette or colour.

A final word

This article was prompted by a happy accident followed by a bit of reading. There are many references to optical illusions in design and typography books. The example image at the start of this article was inspired by one found in the excellent Stop Stealing Sheep and Find Out How Type Works by Erik Spiekermann and E.M. Ginger. There’s also plenty of online material about optical or visual illusions you can dive into. There’s also more on . Oh, and don’t forget the work of M. C. Escher!

Human eyes are amazing. In two sets of watery bags we get a wide-angle lens with incredibly sharp focus and ridiculous depth of field. Apparently our brain is even clever enough to compensate for the lag in the signal getting from retina to cortex. I know next to nothing about ocular science. Spending a morning reading and thinking about optical illusions, and contemplating my own view here in the garden office is pretty awe-inspiring. If only my photographs were as good as my eyes, illusions or no.

Today we released free updates for the Auphonic Leveler Batch Processor and the Auphonic Multitrack Processor with many algorithm improvements and bug fixes for Mac and Windows.

Changelog

• Linear Filtering Algorithms to avoid Asymmetric Waveforms:
  New zero-phase Adaptive Filtering Algorithms to avoid asymmetric waveforms.
  In asymmetric waveforms, the positive and negative amplitude values are disproportionate - please see Asymmetric Waveforms: Should You Be Concerned?.
  Asymmetrical waveforms are quite natural and not necessarily a problem. They are particularly common on recordings of speech, vocals and can be caused by low-end filtering. However, they limit the amount of gain that can be safely applied without introducing distortion or clipping due to aggressive limiting.
• Noise Reduction Improvements:
  New and improved noise profile estimation algorithms and bug fixes for parallel Noise Reduction Algorithms.
• Processing Finished Notification on Mac:
  A system notification (including a short glass sound) is now displayed on Mac OS when the Auphonic Leveler or Auphonic Multitrack has finished processing - thanks to Timo Hetzel.
• Improved Dithering:
  Improved dithering algorithms - using SoX - if a bit-depth reduction is necessary during file export.
• Auphonic Multitrack Fixes:
  Fixes for ducking and background tracks and for very short music tracks.
• New Desktop Apps Documentation:
  The documentation of our desktop apps is now integrated in our new help system:
  see Auphonic Leveler Batch Processor and Auphonic Multitrack Processor.
• Bug Fixes and Audio Algorithm Improvements:
  This release also includes many small bug fixes and all audio algorithms come with improvements and updated classifiers using the data from our Web Service.

About the Auphonic Desktop Apps

We offer two desktop programs which include our audio algorithms only. The algorithms will be computed offline on your device and are exactly the same as implemented in our Web Service.

The Auphonic Leveler Batch Processor is a batch audio file processor and includes all our (Singletrack) Audio Post Production Algorithms. It can process multiple productions at once.

Auphonic Multitrack includes our Multitrack Post Production Algorithms and requires multiple parallel input audio tracks, which will be analyzed and processed individually as well as combined to create one final mixdown.

Please let us know if you have any questions or feedback!

Lots of users have asked us about more customization and control over the sound of our audio algorithms in the past, so today, we have introduced some advanced algorithm parameters for our singletrack version in a private beta program!

• Leveler Presets are basically complete new leveling algorithms
• Maximum Loudness Range (LRA) Target to control the strength of our Leveler
• Maximum True Peak Level
• Better Hum and Noise Reduction Controls

UPDATE Nov. 2018:
We released a complete rework of the Adaptive Leveler parameters and the description here is not valid anymore!
Please see Auphonic Adaptive Leveler Customization (Beta Update)!

Please join our private beta program and let us know how you use these new features or if you need even more control!

Leveler Presets

Our Adaptive Leveler corrects level differences between speakers, between music and speech and will also apply dynamic range compression to achieve a balanced overall loudness. If you don't know about the Leveler yet, take a look at our Audio Examples.

Leveler presets are basically complete new leveling algorithms, which we have been working on in the past few months:
Our current Leveler tries to normalize all speakers to the same loudness. However, in some cases, you might want more or less loudness differences (dynamic range / loudness range) between the speakers and music segments, or more or less compression, etc.
For these use cases, we have developed additional Leveler Presets and the parameter Maximum Loudness Range.

Preset Medium:

This is our current leveling algorithm as demonstrated in the Audio Examples.

Preset Hard:

The hard preset reacts faster and applies more gain and compression compared to the medium preset. It is built for recordings with extreme loudness differences, for example very quiet questions from the audience in a lecture recording, extremely soft and loud voices within one audio track, etc.

Preset Soft:

This preset reacts slower, applies less gain and compression compared to the medium preset. Use it if you want to keep more loudness differences (dynamic narration), if you want your voices to sound "less compressed/processed", for dynamic music (concert/classical recordings), background music, etc.

Preset Softer:

Like soft, but softer :)

Preset Speech Medium, Music Soft:

Uses the medium preset in speech segments and the soft preset in music segments. It is built for music live recordings or dynamic music mixes, where you want to amplify all speakers but keep the loudness differences within and between music segments.

Preset Medium, No Compressor:

Like the medium preset, but only (mid-term) leveling and no (short-term) compression is applied. This preset is optimal if you just use a Maximum Loudness Range Target and want to avoid any additional compression as much as possible.

Maximum Loudness Range (LRA) Target

The loudness range (LRA) indicates the variation of loudness over the course of a program and is measured in LU (loudness units) - for more details see Loudness Measurement and Normalization or EBU Tech 3342.

The parameter Max Loudness Range controls how much leveling is applied:
volume changes of our Adaptive Leveler will be restricted so that the loudness range of the output file is below the selected value.
High loudness range values will result in very dynamic output files, low loudness range values in compressed output audio. If the LRA value of your input file is already below the maximum loudness range value, no leveling at all will be applied.

It is also important which Leveler Preset you select, for example, if you use the soft(er) preset, it won't be possible to achieve very low loudness range targets.

Also, the Max Loudness Range parameter is not such a precise target value as the Loudness Target. The LRA of your output file might be off a few LU, as it is not reasonable to reach the exact target value.

Use Cases: The Maximum LRA parameter allows you to control the strength of our leveling algorithms, in combination with the parameter Leveler Preset. This might be used for automatic mixdowns with different LRA values for different target platforms (very compressed ones like mobile devices or Alexa, very dynamic ones like home cinema, etc.).

Maximum True Peak Level

This parameter sets the maximum allowed true peak level of the processed output file, which is controlled by the True Peak Limiter after our Global Loudness Normalization algorithms.

If set to Auto (which is the current default), a reasonable value according to the selected loudness target is used: -1dBTP for 23 LUFS (EBU R128) and higher, -2dBTP for -24 LUFS (ATSC A/85) and lower loudness targets.

The maximum true peak level parameter is already available in our desktop program.

Better Hum and Noise Reduction Controls

Hum Base Frequency:

Set the hum base frequency to 50Hz or 60Hz (if you know it), or use Auto to automatically detect the hum base frequency in each speech region.

Hum Reduction Amount:

Maximum hum reduction amount in dB, higher values remove more noise.
In Auto mode, a classifier decides how much hum reduction is necessary in each speech region. Set it to a custom value (> 0), if you prefer more hum reduction or want to bypass our classifier. Use Disable Dehum to disable hum reduction and use our noise reduction algorithms only.

Behavior of noise and hum reduction parameter combinations:

Advanced Parameters Private Beta and Feedback

At the moment the advanced algorithm parameters are for beta users only. This is to allow us to get user feedback, so we can change the parameters to suit user needs.
Please let us know your case studies, if you need any other algorithm parameters or if you have any questions!

Auphonic Algorithm Parameters Private Beta Activation

In late August, we launched the private beta program of our advanced audio algorithm parameters. After feedback by our users and many new experiments, we are proud to release a complete rework of the Adaptive Leveler parameters:

In the previous version, we based our Adaptive Leveler parameters on the Loudness Range descriptor (LRA), which is included in the EBU R128 specification.
Although it worked, it turned out that it is very difficult to set a loudness range target for diverse audio content, which does include speech, background sounds, music parts, etc. The results were not predictable and it was hard to find good target values.
Therefore we developed our own algorithm to measure the dynamic range of audio signals, which works similarly for speech, music and other audio content.

The following advanced parameters for our Adaptive Leveler allow you to customize which parts of the audio should be leveled (foreground, all, speech, music, etc.), how much they should be leveled (dynamic range), and how much micro-dynamics compression should be applied.

To try out the new algorithms, please join our private beta program and let us know your feedback!

Leveler Preset

The Leveler Preset defines which parts of the audio should be adjusted by our Adaptive Leveler:

• Default Leveler:
  Our classic, default leveling algorithm as demonstrated in the Leveler Audio Examples. Use it if you are unsure.
• Foreground Only Leveler:
  This preset reacts slower and levels foreground parts only. Use it if you have background speech or background music, which should not be amplified.
• Fast Leveler:
  A preset which reacts much faster. It is built for recordings with fast and extreme loudness differences, for example, to amplify very quiet questions from the audience in a lecture recording, to balance fast-changing soft and loud voices within one audio track, etc.
• Amplify Everything:
  Amplify as much as possible. Similar to the Fast Leveler, but also amplifies non-speech background sounds like noise.

Leveler Dynamic Range

Our default Leveler tries to normalize all speakers to a similar loudness so that a consumer in a car or subway doesn't feel the need to reach for the volume control.
However, in other environments (living room, cinema, etc.) or in dynamic recordings, you might want more level differences (Dynamic Range, Loudness Range / LRA) between speakers and within music segments.

The parameter Dynamic Range controls how much leveling is applied: Higher values result in more dynamic output audio files (less leveling). If you want to increase the dynamic range by 3dB (or LU), just increase the Dynamic Range parameter by 3dB.
We also like to call this Loudness Comfort Zone: above a maximum and below a minimum possible level (the comfort zone), no leveling is applied. So if your input file already has a small dynamic range (is within the comfort zone), our leveler will be just bypassed.

Example Use Cases:
Higher dynamic range values should be used if you want to keep more loudness differences in dynamic narration or dynamic music recordings (live concert/classical).
It is also possible to utilize this parameter to generate automatic mixdowns with different loudness range (LRA) values for different target environments (very compressed ones like mobile devices or Alexa, very dynamic ones like home cinema, etc.).

Compressor

Controls Micro-Dynamics Compression:
The compressor reduces the volume of short and loud spikes like "p", "t" or laughter ( short-term dynamics) and also shapes the sound of your voice (it will sound more or less "processed").
The Leveler, on the other hand, adjusts mid-term level differences, as done by a sound engineer, using the faders of an audio mixer, so that a listener doesn't have to adjust the playback volume all the time.
For more details please see Loudness Normalization and Compression of Podcasts and Speech Audio.

• Auto:
  The compressor setting depends on the selected Leveler Preset. Medium compression is used in Foreground Only and Default Leveler presets, Hard compression in our Fast Leveler and Amplify Everything presets.
• Soft:
  Uses less compression.
• Medium:
  Our default setting.
• Hard:
  More compression, especially tries to compress short and extreme level overshoots. Use this preset if you want your voice to sound very processed, our if you have extreme and fast-changing level differences.
• Off:
  No short-term dynamics compression is used at all, only mid-term leveling. Switch off the compressor if you just want to adjust the loudness range without any additional micro-dynamics compression.

Separate Music/Speech Parameters

Use the switch Separate MusicSpeech Parameters (top right), to see separate Adaptive Leveler parameters for music and speech segments, to control all leveling details separately for speech and music parts:

For dialog intelligibility improvements in films and TV, it is important that the speech/dialog level and loudness range is not too soft compared to the overall programme level and loudness range. This parameter allows you to use more leveling in speech parts while keeping music and FX elements less processed.
Note: Speech, music and overall loudness and loudness range of your production are also displayed in our Audio Processing Statistics!

Example Use Case:
Music live recordings or dynamic music mixes, where you want to amplify all speakers (speech dynamic range should be small) but keep the dynamic range within and between music segments (music dynamic range should be high).
Dialog intelligibility improvements for films and TV, without effecting music and FX elements.

Other Advanced Audio Algorithm Parameters

We also offer advanced audio parameters for our Noise, Hum Reduction and Global Loudness Normalization algorithms:

For more details, please see the Advanced Audio Algorithms Documentation.

We imagine the what-ifs as a worst case scenario, our worst nightmare happening to us, our life falling apart. But here’s another way of looking at it.

Big tech companies have been spying on us for years. This knowledge isn’t new information, but what could be surprising is exactly to what extent each company does it. Security Baron categories what data six of the biggest tech companies collect from you in The Data Big Companies Have On You infographic, and these are just the ones they admit to collecting on their own privacy pages!

The seemingly endless stream of Facebook privacy scandals of late—including the latest involving users as young as 13 years old—may have you questioning how much the social network and other tech giants actually know about you.

The folks at Security Baron examined the privacy policies of Facebook, Google, Apple, Twitter, Amazon, and Microsoft and put together a handy infographic showing the types of data each company admits to collecting. For Facebook and others, data is money. But just how much these tech giants actually know about you might be surprising.

As you can see in the infographic below, Facebook is particularly data-hungry, even gathering information about your work, income level, race, religion, political views, and the ads you click in addition to more commonly collected data points such as your phone number, email address, location, and the type of devices you use.

"Facebook is unusually aggressive," Security Baron pointed out. "This data can be exploited by advertisers and (hopefully not nefarious) others."

Twitter, in comparison, is "comparatively hands-off," the site notes. The microblogging service, for instance, doesn't collect your name, gender, or birthday (Facebook, Google, and Microsoft all do), but Twitter does know your phone number, email address, time zone, what videos you watch, and more.

Google and Microsoft, meanwhile, are the other big players when it comes to collecting data.

"With Cortana listening in and Gmail seeing all of your emails, the ubiquitous nature of Google and Microsoft gives them access to an uncomfortably large amount of your information," Security Baron wrote.

Check out the full infographic below to see what Facebook, Google, Apple, Twitter, Amazon, and Microsoft may know about you. For tips on securing your digital privacy, check our story, "Online Data Protection 101: Don't Let Big Tech Get Rich Off Your Info.

This is a fairly simple infographic design using a comparison table. I think the use of the icons is particularly effective showing which of Google’s or Microsoft’s apps are collecting the data.

Although the types of data are identified down the left side, I wish there was a way to identify the more sensitive types of data.

We study a problem concerning parabolic induction in certain p-adic unitary groups. More precisely, for $E/F$ a quadratic extension of p-adic fields the associated unitary group $G=mathrm{U}(n,n)$ contains a parabolic subgroup $P$ with Levi component $L$ isomorphic to $mathrm{GL}_n(E)$. Let $pi$ be an irreducible supercuspidal representation of $L$ of depth zero. We use Hecke algebra methods to determine when the parabolically induced representation $iota_P^G pi$ is reducible.

In this short note we give a proof of the famous conjecture of Erd"{o}s-Straus for the case $nequiv13 extrm{ mod } 24.$ The Erd"{o}s--Straus conjecture states that the equation $frac{4}{n}=frac{1}{x}+frac{1}{y}+frac{1}{z}$ has positive integer solutions $x,y,z$ for every $ngeq 2$. It is open for $nequiv 1 extrm{ mod } 12$. Indeed, in all of the other cases the solutions are always easy to find. We prove that the conjecture is true for every $nequiv 13 extrm{ mod } 24$. Therefore, to solve it completely, it remains to find solutions for every $nequiv 1 extrm{ mod } 24$.

We study the two-parameter quadratic sieve for a general test function. We prove, under some very general assumptions, that the function considered by Barban and Vehov [BV68] and Graham [Gra78] for this problem is optimal up to the second-order term. We determine that second-order term explicitly.

In this work we study the dynamical behavior Tonelli Lagrangian systems defined on the tangent bundle of the torus $mathbb{T}^2=mathbb{R}^2 / mathbb{Z}^2$. We prove that the Lagrangian flow restricted to a high energy level $ E_L^{-1}(c)$ (i.e $ c> c_0(L)$) has positive topological entropy if the flow satisfies the Kupka-Smale propriety in $ E_L^{-1}(c)$ (i.e, all closed orbit with energy $c$ are hyperbolic or elliptic and all heteroclinic intersections are transverse on $E_L^{-1}(c)$). The proof requires the use of well-known results in Aubry-Mather's Theory.

Temporal event segmentation of a long video into coherent events requires a high level understanding of activities' temporal features. The event segmentation problem has been tackled by researchers in an offline training scheme, either by providing full, or weak, supervision through manually annotated labels or by self-supervised epoch based training. In this work, we present a continual learning perceptual prediction framework (influenced by cognitive psychology) capable of temporal event segmentation through understanding of the underlying representation of objects within individual frames. Our framework also outputs attention maps which effectively localize and track events-causing objects in each frame. The model is tested on a wildlife monitoring dataset in a continual training manner resulting in $80\%$ recall rate at $20\%$ false positive rate for frame level segmentation. Activity level testing has yielded $80\%$ activity recall rate for one false activity detection every 50 minutes.

Event-related potential (ERP) speller can be utilized in device control and communication for locked-in or severely injured patients. However, problems such as inter-subject performance instability and ERP-illiteracy are still unresolved. Therefore, it is necessary to predict classification performance before performing an ERP speller in order to use it efficiently. In this study, we investigated the correlations with ERP speller performance using a resting-state before an ERP speller. In specific, we used spectral power and functional connectivity according to four brain regions and five frequency bands. As a result, the delta power in the frontal region and functional connectivity in the delta, alpha, gamma bands are significantly correlated with the ERP speller performance. Also, we predicted the ERP speller performance using EEG features in the resting-state. These findings may contribute to investigating the ERP-illiteracy and considering the appropriate alternatives for each user.

Representation learning is a critical ingredient for natural language processing systems. Recent Transformer language models like BERT learn powerful textual representations, but these models are targeted towards token- and sentence-level training objectives and do not leverage information on inter-document relatedness, which limits their document-level representation power. For applications on scientific documents, such as classification and recommendation, the embeddings power strong performance on end tasks. We propose SPECTER, a new method to generate document-level embedding of scientific documents based on pretraining a Transformer language model on a powerful signal of document-level relatedness: the citation graph. Unlike existing pretrained language models, SPECTER can be easily applied to downstream applications without task-specific fine-tuning. Additionally, to encourage further research on document-level models, we introduce SciDocs, a new evaluation benchmark consisting of seven document-level tasks ranging from citation prediction, to document classification and recommendation. We show that SPECTER outperforms a variety of competitive baselines on the benchmark.

Due to the exponential growth of biomedical literature, event and relation extraction are important tasks in biomedical text mining. Most work only focus on relation extraction, and detect a single entity pair mention on a short span of text, which is not ideal due to long sentences that appear in biomedical contexts. We propose an approach to both relation and event extraction, for simultaneously predicting relationships between all mention pairs in a text. We also perform an empirical study to discuss different network setups for this purpose. The best performing model includes a set of multi-head attentions and convolutions, an adaptation of the transformer architecture, which offers self-attention the ability to strengthen dependencies among related elements, and models the interaction between features extracted by multiple attention heads. Experiment results demonstrate that our approach outperforms the state of the art on a set of benchmark biomedical corpora including BioNLP 2009, 2011, 2013 and BioCreative 2017 shared tasks.

Cyber-physical systems for robotic surgery have enabled minimally invasive procedures with increased precision and shorter hospitalization. However, with increasing complexity and connectivity of software and major involvement of human operators in the supervision of surgical robots, there remain significant challenges in ensuring patient safety. This paper presents a safety monitoring system that, given the knowledge of the surgical task being performed by the surgeon, can detect safety-critical events in real-time. Our approach integrates a surgical gesture classifier that infers the operational context from the time-series kinematics data of the robot with a library of erroneous gesture classifiers that given a surgical gesture can detect unsafe events. Our experiments using data from two surgical platforms show that the proposed system can detect unsafe events caused by accidental or malicious faults within an average reaction time window of 1,693 milliseconds and F1 score of 0.88 and human errors within an average reaction time window of 57 milliseconds and F1 score of 0.76.

With the rapidly worldwide spread of Coronavirus disease (COVID-19), it is of great importance to conduct early diagnosis of COVID-19 and predict the time that patients might convert to the severe stage, for designing effective treatment plan and reducing the clinicians' workloads. In this study, we propose a joint classification and regression method to determine whether the patient would develop severe symptoms in the later time, and if yes, predict the possible conversion time that the patient would spend to convert to the severe stage. To do this, the proposed method takes into account 1) the weight for each sample to reduce the outliers' influence and explore the problem of imbalance classification, and 2) the weight for each feature via a sparsity regularization term to remove the redundant features of high-dimensional data and learn the shared information across the classification task and the regression task. To our knowledge, this study is the first work to predict the disease progression and the conversion time, which could help clinicians to deal with the potential severe cases in time or even save the patients' lives. Experimental analysis was conducted on a real data set from two hospitals with 422 chest computed tomography (CT) scans, where 52 cases were converted to severe on average 5.64 days and 34 cases were severe at admission. Results show that our method achieves the best classification (e.g., 85.91% of accuracy) and regression (e.g., 0.462 of the correlation coefficient) performance, compared to all comparison methods. Moreover, our proposed method yields 76.97% of accuracy for predicting the severe cases, 0.524 of the correlation coefficient, and 0.55 days difference for the converted time.
