Audio and video trends 2022

There’s no doubt that the audio visual industry has proven its ability to survive and thrive in trying times. Global events have facilitated the rapid evolution of audio visual technologies, and these only continue to advance. Here are some audio visual trends for 2022 collected from many sources (click the link colored to text to get to the information source):

Growing consumer demand for audio content: People are listening to all forms of audio content: news, music, podcasts and books. Nielsen reports 75 per cent of people working from home are streaming music every week, with 40 per cent tuning in daily.

Rapid smart speaker adoption: Smart speakers and voice assistants are becoming common home appliances. One-third of U.S. households are equipped with smart speakers and 44 per cent of U.S. adults use voice assistants. Smart speakers let listeners to respond to ads using voice commands. Consumers are rapidly embracing voice to access information, entertain themselves and shop. The ability to instantly answer consumers’ questions and help them solve problems is becoming a key advantage for marketers who lean into audio.

Digital Audio is becoming multi-devices: Historically, digital audio has been widely consumed via mobile devices; it can now also be launched from a variety of new technologies including tablets, connected speakers, TVs and even smart watches.

Prosumer audio: Prosumer audio gear has remained on a steady upward curve over the last few years. With podcasting, live streaming, and at-home work solutions more popular than ever, it’s been a fantastic few years for prosumer audio sales. Their need for reliable, slightly elevated gear to take their content to the next level is proving highly profitable for certain companies.

Social sound: Audio fans are getting more social than ever, thanks to new apps that allow like-minded users to communicate without the screen fatigue or doom-scrolling associated with photo and video-based social networks.

3D audio: Spatial or 3D audio has firmly found its footing in the video game industry, with Sony and Microsoft’s next-gen consoles both natively supporting the feature.

Content Still Rules: Audiophiles are fiercely loyal to their favorite DJs, hosts, podcasters, artists and stations. As a result, they’re spending more time than ever listening to audio daily. Listeners consume programming on their own terms.

Streaming rules: Streaming music now account for more than 85% of all music enjoyed. Only 6% of music is now downloaded, even less than is physically purchased in the form of records, CDs, or the last tapes.

TikTok has caused a seismic shift in the world of content creation, skewing it ever further into a mobile-first industry. To capitalise on the market, more and more mobile-friendly gear is being created, forgoing the need for hundreds of adaptors and plugging straight into AUX, USB-C, or iPhone ports (or working wirelessly).

Many amplifier technologies in use: While classic class AB amplifiers are more and more often replaced with class D amplifier technology, there is still special audiophile markets for class A amplifiers and tube based amplifiers. New technology just coming to the class D amplifiers are GaN-based audio amplifier powered with switch mode power supply. They promise premium audio systems with good sound quality in a small and light format.

Vinyl records: Vinyl is here to stay, it seems, despite all technological advances that would have seemed to threaten it. Vinyl records (and coincidentally, cassette tapes) are selling like hot cakes again. Vinyl sales have been steadily rising for some time, but in 2020 for the first time in 34 years, vinyl has surpassed CD sales.

Streaming has killed CD: CDs sales are continuously and quickly declining thanks to streaming and music flash drives.

The race to wireless zero latency: Companies around the world are racing to find a solution that all but eliminates latency from wireless audio, removing the need for cables in an increasingly space, waste, and aesthetically-conscious world.

Green screens: As events become more hybrid, green screens will play a significant role, enabling speakers to be placed directly in the content becoming part of the message. Green screens are a great cost-effective way to insert branding and infographics, which works perfectly for online events and we will see them become adopted further for conferences. There are also cameras with depth sense features and software that can use pretty many background for green screen type effects without building a real green screen.

Hybrid events: Events have had to embrace the constant mix of who can attend, who can possibly attend and who is not afraid to attend and as such have flipped to hybrid. Although not necessarily an AV trend, hybrid events are unsurprisingly on the increase as people work from home and corporate travel is halted. In those events content needs to be clear and targeted to get the information across efficiently. There is demand for standalone apps that can enhance hybrid events such as Slack, Slido and Survey Monkey.

4k UHD: We will see more quality content produced in 4K UHD to ensure graphics can stand up to the state-of-the-art vision sources that are being employed in venues. If you are not creating content in 4K UHD then you are not taking advantage of all that is available to project your message.

Touchless Environments: COVID-19 has accelerated the desire for automation and touchless environments from a nice-to-have to a must-have. They minimize the amount that people come into contact with shared surfaces. Following the throes of COVID-19, it appears that touchless building controls are here to stay.

Remote Control And Remote Management: We’re seeing an increase in demand for remote management software that allows one person, or a small group of people, to log into a remote system and review the status of a set of classrooms or meeting spaces. Increasingly in 2022, companies can implement remote monitoring and maintenance for audio visual systems to support the advancement of technology. Whether your organization is expansive or small, remote audio visual support teams can significantly reduce operating costs for your business.

Live Streaming: As more people look to tune into events from home, we’re seeing an increased need for equipment that supports live streaming.

Video Walls: In many commercial spaces, there’s often a need for a large video display. In past years, many spaces have opted for projection screens as opposed to large LCD displays or video walls, solely because the cost was much lower. The price of video walls getting close to similar to a projection screen, and the benefits almost always outweigh the slightly higher cost.

Service And Maintenance: As more commercial spaces look for ways to save, there’s been an increasing demand for AV integrators to handle service and maintenance in order to maximize the lifespan of AV products. Businesses are focussing on reducing the overhead costs associated with maintaining and installing the equipment. Companies having expertise in sectors other than AV cannot have a dedicated team to manage and monitor their AV equipment.

Snake oil: Many audiophiles are infected by the snake oil curse, which causes them to chase endlessly after what is supposedly better sound reproduction. Audio interconnect and speaker cables have become a profitable business built on imaginative marketing and misinformation. This market now extends into power cords, HDMI, and optical cables. Untold sums of money have been wasted on the fanciful claims of cable vendors. There is lots of ridiculous pieces of pseudo-audiophile nonsense out there. Try to avoid this bullshit in 2022. Try to to restore peace of mind, and the enjoyment of music.

Hybrid environment: Although some employees are returning to the office, it is doubtful that society will return to an entirely on-site work environment. Remote workspaces from 2020-21 on will now be ‘Hybrid’ (home and office). AV technologies are playing a crucial role in creating a modern working environment. Hybrid technologies are changing their form, we had just a Skype call before the pandemic and now we have Zoom, Microsoft Team Rooms, Google Meet, etc with more advanced features allowing space for seamless collaboration and communication. Hybrid environments are expected to go beyond that with continuous innovation and development. Remote employees, distant customers, healthcare providers, and educational institutions can utilize unified communication solutions. It is now increasingly important to adopt technologies that make collaboration easier. At one time, frequent video communications, online learning, and compact hardware design were ambitious audio visual innovations that were hard for people to imagine. Today, they’re top priorities for business, educational, and religious spaces of all types, and are critical to how people interact in those spaces.

Silent Video Gains Momentum: It’s estimated that 85% of short videos viewed on Facebook are watched without sound. Yet as much as 41% of video would be incomprehensible to viewers without sound. Video marketers are using captions, context and other “no-audio” tactics to convey information.

Social Media Goes Video-First: video content is one of the internet’s main attractions. Users are being drawn to video-first platforms. One of the most common reasons people use social media is to view video. But with video streaming set to be as much as 82% of total web traffic by 2022, the importance of video content to marketing strategy is massive and still growing.

Digital audio: Digital audio consumption accelerated in 2021 and commercial engagement followed the audiences. In 2022 we foresee three key commercial trends in the digital audio space: Data-led targeting capabilities provide a powerful way to get advertising cut through, Creativity is a constant rather than a ‘trend’ in advertising and Audience Growth is attracting new advertisers. Programmatic audio is divided into three main supply sources – music streaming (through suppliers like Spotify), podcasts (the biggest opportunity for brands), and online broadcast radio (now more attractive with the addition of data overlay opportunities). Amongst these audio heavyweights we can see emerging innovation in the form of conversational and actionable audio ads.

Virtual and Augmented Reality: Although virtual and augmented reality first entered the public consciousness via video games or social media filters, they are now infiltrating every aspect of our lives. Given the rapid evolution of technology, it is inevitable that these advancements will impact the audio visual industry. Companies specializing in the development of VR and AR technologies are noticing an increase in interest from educational institutions wishing to create an enhanced learning experience. Within the healthcare sector, VR solutions are assisting healthcare professionals with socializing medically isolated patients. Virtual reality has been in development within the audio visual industry for many years. In 2022, virtual reality is becoming mainstream. Or at least tries.

Shift from linear TV to streaming: Video streaming goes beyond traditional TV viewing for people under 45. The lion’s share of viewing by those over 45 is still grabbed by linear television.

    What’s Bluetooth LE Audio? Explaining the spec and what it means for wireless sound
    Spec completion signals better and, potentially, cheaper cable-free audio

    On Tuesday, the Bluetooth Special Interest Group (SIG), the industry group that makes the Bluetooth wireless standard, announced the completion of its latest specification: Bluetooth Low Energy (LE) Audio. Like Bluetooth LE, Bluetooth LE Audio focuses more on power efficiency than the classic version of Bluetooth. It also seeks to provide better audio quality than standard Bluetooth and introduces new features.

    Bluetooth LE Audio release date
    There are no Bluetooth LE Audio products available yet, and release dates are hard to pinpoint because they’re based on individual vendors. However, in its announcement, Bluetooth SIG said that the first consumer offerings “are expected to come to market in the coming months, and the Bluetooth SIG anticipates LE Audio product availability to ramp up as we approach the holiday season and end of the year.”

    Bluetooth SIG today announced the full set of specifications for Bluetooth LE Audio. This is great news because when it first announced Bluetooth LE Audio in January 2020, the expected spec release date was in the first half of 2020. And work on the spec has been ongoing since at least 2015. Apparently, Bluetooth LE Audio was the “largest specification development project in the history of the Bluetooth SIG,” according to a statement from Mark Powell, Bluetooth SIG’s CEO.

    The industry group also said today that companies could earn the qualification to add Bluetooth LE Audio support to their products.

    “Compact disc, you are underrated and you will always have a place in my heart”

    Ableton Live co-creator Robert Henke says that it’s time to stop pressing vinyl and “fully embrace CDs”
    By Ben Rogerson ( Computer Music , Future Music , emusician ) published 2 days ago

    “Compact disc, you are underrated and you will always have a place in my heart”

    It might not be the most cool physical music format right now – even the previously-derided cassette has more hipster cache – but artist and Ableton Live co-creator Robert Henke thinks that it’s time once again to “fully embrace” the CD.

    In a conversation-starting Facebook post(opens in new tab), Henke has taken aim at the vinyl revival and says that the compact disc is a better alternative for people who still want an actual ‘thing’ when they buy their music.

    “I still love physical products,” he says, “but manufacturing big heavy plates of plastic and have [sic] them shipped around the globe is a huge waste of energy and resources.”

    Streaming royalties are broken, Rashida Tlaib thinks Congress can fix them
    The Michigan congresswoman is prepping legislation aimed to change how musicians get paid

    There’s never been an easy time to be a musician, but for many in and around the industry, the 21st century has presented one calamity after another for those hoping to make a living through music. The turn of the century saw record labels implode at a staggering rate, and it would be some time before some salvation arrived in the form of streaming services, which finally offered an effective method to monetize music listening.

    Examined in the harsh light of day, however, a major question emerges: Who, precisely, do these services benefit? According to the Record Industry Association of America, streaming comprised 83% of all recorded music revenue in the U.S., as of 2020. Calculating the amount of revenue an artist makes per stream can be a complex task.

    The commonly accepted figure for Spotify is that somewhere between $0.003 and $0.005 is paid out to artists for every stream. The figure varies widely from service to service, though it’s generally fractions of a cent. Apple, notably, revealed last April that it pays around a penny per stream — a generous figure by streaming industry standards.

    Revenue rates have, of course, been a common complaint among musicians for more than a decade, but like so many other labor issues, things have come to a head during the pandemic. Two-plus years of limited or no touring have brought concerns into sharp relief.

    Re-Creating The Unique Look Of Unobtainable Aerochrome Film

    Ever heard of Aerochrome? It’s a unique type of color infrared film, originally created for the US military and designed for surveillance planes. Photos taken with Aerochrome film show trees and other vegetation in vivid reds and pinks, creating images that aren’t quite like anything else.

    Sadly, Aerochrome hasn’t been made for over a decade. What’s an enterprising hacker with a fascination for this unobtainable film to do? [Joshua] resolved to recreate it as best he could, and the results look great!

    Aerochrome isn’t quite the same as normal film. It is sensitive to infrared, and photos taken with it yield a kind of false color image that presents infrared as red, visible reds as greens, and greens are shown as blue. The result is a vaguely dreamy looking photo like the one you see in the header image, above. Healthy vegetation is vividly highlighted, and everything else? Well, it actually comes out pretty normal-looking, all things considered.

    Aerochrome may be out of production, but black and white infrared film is still available. [Joshua] found that he could re-create the effect of Aerochrome with an adaptation of trichrome photography: the process of taking three identical black and white photos, each using a different color filter. When combined, the three photos (acting as three separate color channels) produce a color image.

    Tiny and Flexible Cameras Sip Power
    July 28, 2022
    ams Osram’s Daniel Vander Ley shows off a collection of compact, low-power video cameras for applications from automotive to fruit analysis.|7211D2691390C9R&oly_enc_id=7211D2691390C9R

    Daniel Vander Ley, Product Marketing Manager for the Visualization and Laser asm OSRAM Group, shows off some of the cameras in applications ranging from fruit analysis to car driver head tracking.

    One of the cameras that Daniel highlights is the NanEyeM (Fig. 1). This tiny sensor utilizes a 10-bit ADC to deliver a 320- × 320-pixel resolution in a 1-mm2 package. It has a 49 frame/s rate with a 2.4-µm rolling shutter. It was initially designed for medical endoscopic applications. It’s available in cable lengths up to 3 m. Other applications include AR/VR headsets and even robots and mini-drones.

    Osram has a range of imaging solutions, many of which are going into automotive applications like driver head tracking (Fig. 2). This can be used to make sure the driver is paying attention to the road. The demo uses a machine-learning model to recognize the face from the 3D imaging information from the sensor.

    The fruit demo uses a sensor that detects the surface of fruit, such as an apple. It can determine details like sugar content based on video analysis from the sensor.

    Hackaday Prize 2022: A Plasma Tweeter For Ultimate Clarity

    In the world of audio there are a huge variety of esoteric technologies which are rarely seen. One such is the plasma tweeter, a type of loudspeaker which generates sound by modulating a small electrical discharge. The benefit of this design comes in its delivering the closest possible to a point audio source, in effect the theoretical ideal speaker for treble frequencies. They’re a little hazardous due to the voltage but aren’t too difficult to make, as demonstrated by [Mircemk] whose version uses a recycled power pentode tube — which is how it showed up in the Hack it Back round of the Hackaday Prize.

    DIY Plasma Tweeter (speaker)

    This projectdescribes the making of an unusual tweeter speaker that is much appreciated in the high-end audio class.

    How to take astronomy photos with just your iPhone

    Although the iPhone isn’t nearly as powerful as a telescope, it’s still able to take good night sky photos. Here’s how to get started with it.

    iPhone long exposure
    Apple released Live Photos alongside the iPhone 6s in 2015, which was the first step toward this category. In between a GIF and a video, a Live Photo captures activity just before and after a photo is taken. These photos capture motion, revealed by long-pressing the still image in the Photos app.

    With iOS 11 Live Photos received a few editing options for “Loop,” “Bounce,” and “Long Exposure.” The option for Long Exposure uses algorithms to mimic long exposure photography.

    Streaming Services Deal With More Subscribers Who ‘Watch, Cancel and Go’
    Customer loyalty to Netflix, Hulu, HBO Max and other services declines amid stiffer competition

    Kate Bigel is the kind of customer who is frustrating streaming-video companies.

    She and her husband regularly rotate through the big streaming services, canceling one and signing up for another depending on which is carrying the shows they want at a given time. They started the practice about a year ago to save money.

    “You’ve got to trim the pennies. It’s like a diet, you know—you take a couple calories off here and there,” and it makes a difference, said Ms. Bigel, a retired game-industry art director in San Diego. “Why give them money if I’m not watching?”

    It is gradually getting tougher for streaming-video companies to hold on to their subscribers, as consumers who are flooded with options weed out services they don’t need at any given time.

    Some 19% of subscribers to premium services—a group that includes Netflix, Hulu, AppleTV+, HBO Max and Disney+, among others—canceled three or more subscriptions in the two years up to June, according to new data from subscriber-measurement firm Antenna. That is up from 6% in the two-year stretch ended in June 2020.

    “The more people you have in a household using the service, the stickier it is,” said JB Perrette, Warner Bros. Discovery’s head of streaming. “At the end of the day, putting all the content together was really the only option we saw in making this a viable business.”

    New Intel chips won’t play Blu-ray disks due to SGX deprecation

    Intel has removed support for SGX (software guard extension) in 12th Generation Intel Core 11000 and 12000 processors, rendering modern PCs unable to playback Blu-ray disks in 4K resolution.

    This technical problem arises from the fact that Blu-ray disks require Digital Rights Management (DRM), which needs the presence of SGX to work.

    This is a feature that Intel introduced in the Skylake generation back in 2016, enabling PCs to play protected Blu-ray disks for the first time.

    Your Favorite Media Player Is Now Banned In India

    VLC Media Player Is Now Banned, But It Still Working For All

    VLC Media Player is now banned in India, which seems to restrict accessing its website and following the download link.

    At the same time, it is still working in the country and is also available to download from some major stores.

    As many reports suggest, this ban is not a new action by the Indian Government; actually, this ban took place many months ago, nearly six months ago, which means maybe in February.

    On average, every third desktop user uses VLC as the primary media player over the various Windows option.

    According to sources, this ban is also the result of the previous 54 Chinese-app prohibitions, which were done at the beginning of this year, but the Ministry hasn’t released any official statement.

    This ban was said for desktops, but it is not like that, and I think Government only finds issues with its downloading server and website. Also, it’s working well for those who have already installed it.

    Expected Reason For BAN
    A website named MediaNama suggested that the Chinese hacking group Cicada used the program to deploy malicious code on target machines, and the group had earlier been spotted running many campaigns.

    And for clarity, VLC is not from China, and it is from a France-based group.

    VLC says India internet providers blocking site poses threat to users

    VideoLan, the developer of popular media player VLC, says Indian telecom operators have been blocking its website since February of this year in a move that is potentially impacting some users in one of the open source firm’s largest markets.

    “Most major ISPs [internet service providers] are banning the site, with diverse techniques,” VideoLan president and lead developer Jean-Baptiste Kempf said of the blocking in India, in an email to TechCrunch.

    The telecom operators began blocking the VideoLan website on February 13 of this year, when the site saw a drop of 80% in traffic from the South Asian market, he said.

    India represents 10% of all VLC users worldwide, he said. The website’s traffic has seen an overall drop of 20% as a result of the blocking in India.

    Indian telecom operators have not explained why they have blocked the VideoLan website, but some speculate that it could be because of a misinterpretation of a security warning from earlier this year.

    Young adults in the UK are spending more time scrolling on social media site TikTok than watching broadcast television, according to an Ofcom report on Wednesday that highlights the growing generational divide in media habits.

    In its annual survey of consumption trends, the media regulator found that those aged 16 to 24 spent an average of 53 minutes a day viewing traditional broadcast TV, just a third of the level a decade ago.

    By contrast, people over the age of 65 spent seven times as long in front of channels such as BBC One or ITV, viewing almost six hours’ worth of broadcast TV a day — a figure that has risen since 2011.

    Math error: A new study overturns 100-year-old understanding of color perception

    A new study corrects an important error in the 3D mathematical space developed by the Nobel Prize-winning physicist Erwin Schrödinger and others, and used by scientists and industry for more than 100 years to describe how your eye distinguishes one color from another. The research has the potential to boost scientific data visualizations, improve TVs and recalibrate the textile and paint industries.

    “The assumed shape of color space requires a paradigm shift,”

    “Our research shows that the current mathematical model of how the eye perceives color differences is incorrect. That model was suggested by Bernhard Riemann and developed by Hermann von Helmholtz and Erwin Schrödinger—all giants in mathematics and physics—and proving one of them wrong is pretty much the dream of a scientist,” said Bujack.

    Modeling human color perception enables automation of image processing, computer graphics and visualization tasks.

    “Our original idea was to develop algorithms to automatically improve color maps for data visualization, to make them easier to understand and interpret,” Bujack said. So the team was surprised when they discovered they were the first to determine that the longstanding application of Riemannian geometry, which allows generalizing straight lines to curved surfaces, didn’t work.

    To create industry standards, a precise mathematical model of perceived color space is needed. First attempts used Euclidean spaces—the familiar geometry taught in many high schools; more advanced models used Riemannian geometry. The models plot red, green and blue in the 3D space. Those are the colors registered most strongly by light-detecting cones on our retinas, and—not surprisingly—the colors that blend to create all the images on your RGB computer screen.

    In the study, which blends psychology, biology and mathematics, Bujack and her colleagues discovered that using Riemannian geometry overestimates the perception of large color differences. That’s because people perceive a big difference in color to be less than the sum you would get if you added up small differences in color that lie between two widely separated shades.

    Riemannian geometry cannot account for this effect.

    “We didn’t expect this, and we don’t know the exact geometry of this new color space yet,” Bujack said. “We might be able to think of it normally but with an added dampening or weighing function that pulls long distances in, making them shorter. But we can’t prove it yet.”
