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.
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.
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.
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.

Todd Spangler / Variety:
Nielsen: in July, streaming topped both cable and broadcast for the first time in the US, with a 34.8% share; Netflix had an 8% share, and YouTube had 7.3% — Americans now watch more stuff on TV from streaming services than either broadcast or cable TV. — Streaming platforms …
U.S. Streaming Tops Cable TV Viewing for First Time, Nielsen Says
https://variety.com/2022/digital/news/streaming-tops-cable-tv-viewing-nielsen-1235344466/
Americans now watch more stuff on TV from streaming services than either broadcast or cable TV.
Streaming platforms, led by Netflix, in July 2022 for the first time surpassed cable networks to claim the largest share of U.S. TV viewing for the month, according to new data from Nielsen. It was only a matter of time before the milestone was reached, as streaming usage has continued to climb while traditional TV declines amid the steady drip-drip-drip of cord-cutting losses.
For the month of July, streaming among American TV households represented a record 34.8% share of total consumption, while cable and broadcast came in at 34.4% and 21.6%, respectively. Streaming usage has surpassed that of broadcast before, but this is the first time it has also exceeded cable viewing.
Overall, streaming usage in July increased 3.2% compared with June and gained 1.1 share points. Time spent streaming in July averaged nearly 191 billion minutes per week, and each of the five measurement weeks in July 2022 now account for five of the six highest-volume streaming weeks on record, according to Nielsen.

Livestreaming Backpack Takes Streaming On-The-Go
https://hackaday.com/2022/08/19/livestreaming-backpack-takes-streaming-on-the-go/
Anyone who’s anyone on the internet these days occasionally streams content online. Whether that’s the occasional livestream on YouTube or an every day video game session on Twitch, it’s definitely a trend that’s here to stay. If you want to take your streaming session on the go, though, you’ll need some specialized hardware like [Melissa] built into this livestreaming backpack.
[Melissa] isn’t actually much of a streamer but built this project just to see if it could be done. The backpack hosts a GoPro camera with a USB interface, mounted on one of the straps of the pack with some 3D printed parts, allowing it to act as a webcam. It is plugged into a Raspberry Pi which is set up inside the backpack, and includes a large heat sink to prevent it from overheating in its low-ventilation environment. There’s also a 4G modem included along with a USB battery pack to keep everything powered up.

Reactive Load For Amplifiers Teaches Lessons About Inductors
https://hackaday.com/2022/08/24/reactive-load-for-amplifiers-teaches-lessons-about-inductors/
The sound produced by any given electric guitar is shaped not just by the instrument itself but by the amplifiers chosen to make that sound audible. Plenty of musicians swear by the warm sound of amplifiers with vacuum tube circuits, but they do have some limitations. [Collin] wanted to build a reactive load for using tube amps without generating a huge quantity of sound, and it resulted in an interesting project that also taught him a lot about inductors.
The reactive load is essentially a dummy load for the amplifier that replaces a speaker with something that won’t produce sound. Passive loads typically use resistor banks but since this one is active, it needs a very large inductor to handle the amount of current being produced by the amplifier. [Colin] has also built a headphone output into this load which allows it to output a much smaller quantity of sound to a headset while retaining the sound and feel of the amplifier tubes, and it additionally includes a widely-used tone control circuit as well.

Automotive instrument clusters are in the middle of a revolution. The cluster is rapidly becoming a part of the larger infotainment ecosystem. Consumers are driving around with intelligent, quickly evolving displays on their dash, but the audio chimes – the essential driver alerts that come from a speaker housed inside the cluster – are lagging behind.
Cluster audio does not get the attention that a vehicle’s central head unit audio gets. Advances in low-power audio technology are enabling new trends in cluster systems, however.

The Mogami is relatively immune to RFI/EMI because it’s a star-quad cable with (electrically) floating Neutrik connectors. You can get similar rejection characteristics for a bit less by looking for cables made with Canare star-quad cable stock and Neutrik connectors. For example B&H and several other retailers sell “own-brand” cables in that configuration for $25-35/cable, vs $50 for the Mogamis.

3M Faces $100 Billion in Losses From Veterans’ Earplug Suits, Expert Says
https://www.bloomberg.com/news/articles/2022-08-16/3m-faces-100-billion-in-losses-from-veteran-suits-expert-says?leadSource=uverify+wall
Adviser hired by lawyer suing 3M says company faces bankruptcy
Plaintiff lawyers seek to restrict 3M payouts like dividend
3M Co. faces more than $100 billion in losses and bankruptcy because of lawsuits brought by veterans who blame their hearing problems on faulty earplugs, according to a litigation consultant hired by lawyers suing the industrial conglomerate.
Initial results from a handful of test cases shows 3M would be swamped by losses should the more than 230,000 lawsuits related to the company’s military earplugs business go forward, the plaintiff’s adviser J.B. Heaton testified in bankruptcy court Tuesday.
“It is more and more likely within the next several years we’ll see a 3M bankruptcy, yes,” Heaton told US Bankruptcy Judge Jeffrey J. Graham during a hearing in federal court in Indianapolis.
“We strongly disagree with this unsupported and clearly flawed speculation,” company communications manager Sean Lynch said in an emailed statement. “3M has committed to provide $1 billion to a trust for claimants determined to be entitled to compensation.”
Some advocates for the suing soldiers want Graham to block 3M from paying any shareholder dividends, buying back any of its stock or spinning off any assets, if the judge also decides to halt the lawsuits.
Restricting how 3M spends its cash will protect money and other assets that could be used to compensate soldiers who have had their hearing damaged by the earplugs, the advocates said in court papers.

Feature-Packed Automotive Audio ADC Sports 123-dB SNR, 768-kHz Rate
Aug. 29, 2022
The PCM6120-Q1 is a software-programmable analog-to-digital converter IC that supports the microphone-based needs of automobiles and other high-end audio applications.
https://www.electronicdesign.com/markets/automotive/article/21249601/electronic-design-featurepacked-automotive-audio-adc-sports-123db-snr-768khz-rate?utm_source=EG+ED+Auto+Electronics&utm_medium=email&utm_campaign=CPS220902077&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
Automotive audio functions and performance receive lots of attention, especially with respect to higher-power audio amplifiers featuring ultra-low total harmonic distortion (THD) and related specifications. Obviously, high-performance digital-to-analog converters (DACs) are key elements in audio-output signal chain. But today’s cars go far beyond creating sound, as they must also capture and digitize it with accuracy and high signal-to-noise ratio (SNR) from two or more microphones.
Targeting these applications is the Texas Instruments PCM6120-Q1, a stereo automotive audio analog-to-digital converter (ADC) specified at 123-dB SNR with its dynamic range enhancer (DRE) enabled (and 113-dB with DRE disabled) and 768-kHz maximum sampling rate.
Applications include automotive active-noise cancellation, “head” units, rear-seat entertainment, digital-cockpit processing units, and even the telematics control unit. Non-automotive applications range from voice-activated systems, professional microphones, audio conferencing, and portable computing to communication and entertainment designs.

There are much better ways to do this with Google slides.
1. Create Google slide with sinage content.
2. Create share link for the presentation
3. Set home page of display screen browser to that presentation link.
4. Set browser to auto load in full-screen mode on boot
Bonus. Any updates you make to the Google slide will automatically apply to the presentation in real time.
TV might only have a crappy browser available?
true. But I’ve set this up many times on old PCs running Lubuntu. Works like a charm on hardware that most ppl would throw out.
yeah. The Google presentation would also run on literally any browser, including the ones built in to smart TVs. But it’s just a matter of getting rid of that top bar.

Testing Loudspeakers: Which Measurements Matter, Part 1
https://audioxpress.com/article/testing-loudspeakers-which-measurements-matter-part-1
The controversy over subjective versus objective loudspeaker evaluation has raged on for decades. However, to my mind, there is no controversy. These criteria are simply two faces of the same coin. When describing how a loudspeaker sounds, using terms such as neutral frequency balance, musicality, midrange transparency, graininess, harshness, imaging, ambience, and others in the reviewer’s lexicon is totally appropriate. As a loudspeaker designer, however, these subjective terms do not tell me how to design a loudspeaker.

How The BBC (Still) Sends Audio To Transmitter Sites
https://hackaday.com/2022/09/13/how-the-bbc-still-sends-audio-to-transmitter-sites/
Running a radio station is, on the face of it, a straightforward technical challenge. Build a studio, hook it up to a transmitter, and you’re good to go. But what happens when your station is not a single Rebel Radio-style hilltop installation, but a national chain of transmitter sites fed from a variety of city-based studios? This is the problem facing the BBC with their national UK FM transmitter chain, and since the 1980s it has been fed by a series of NICAM digital data streams. We mentioned back in 2016 how the ageing equipment had been replaced with a modern FPGA-based implementation without any listeners noticing, and now thanks to [Matt Millman], we have a chance to see a teardown of the original 1980s units. The tech is relatively easy to understand from a 2020s perspective, but it still contains a few surprises.
In each studio or transmitter site would have been a 19″ rack containing one of these units — a card frame with a collection of encoder or decoder cards. These are all custom-made by the BBC’s engineering department to a very high standard, and use period parts such as the familiar Z80 microprocessor and some Philips digital audio chips, which followers of high-end consumer audio may recognize. As you’d expect for a mission critical device, many of the functions are duplicated for redundancy, with their outputs compared to give warning of failures.

Elokuvakamera kuvaa 120 ruutua sekunnissa 4.6K-tarkkuudella
https://etn.fi/index.php/13-news/14004-elokuvakamera-kuvaa-120-ruutua-sekunnissa-4-6k-tarkkuudella
Kamerakennoistaan tunnettu onsemi kertoo kehittäneensä mukautetun huippuluokan CMOS-kennon ARRI:n ALEXA 35 -kameralle. Kamera käyttää onsemin ALEV 4 Super 35 4,6K CMOS -kuvakennoa, joka tuottaa 4608 x 3164 pikselin (14,6 megapikselin) resoluution.
Pikselien väli on 6,075 mikrometriä. Kenno pystyy kuvaamaan 120 ruutua sekunnissa. Sensorissa on onsemin uusin tekniikka pikselivasteen optimoimiseksi, High Dynamic Range -tekniikat (HDR) ja pikselien tasaisuuden parantaminen suurilla nopeuksilla luettaessa; tekniikoita, joita käytetään myös onsemin teollisuuslaitteiden antureissa.
ARRIn kaikki digitaaliset elokuvakamerat – alkaen ensimmäisestä ARRIFLEX D-20:sta vuonna 2005 ja sen jälkeen ensimmäisestä ALEXAsta, joka toimitettiin kesäkuussa 2010 aina tänä vuonna esiteltyyn ALEXA 35 -kameraan asti – perustuvat onsemin kanssa yhteistyössä kehitettyihin CMOS-antureihin.

Eyeglass Reflections Can Leak Information During Video Calls
https://www.securityweek.com/eyeglass-reflections-can-leak-information-during-video-calls
A group of academic researchers have devised a method of reconstructing text exposed via participants’ eyeglasses and other reflective objects during video conferences.
Zoom and other video conferencing tools, which have been widely adopted over the past couple of years as a result of the Covid-19 pandemic, may be used by attackers to leak information unintentionally reflected in objects such as eyeglasses, the researchers say.
“Using mathematical modeling and human subjects experiments, this research explores the extent to which emerging webcams might leak recognizable textual and graphical information gleaming from eyeglass reflections captured by webcams,” the academics note in their research paper.
According to the researchers, evolving webcam technology may result in optical attacks that rely on using multiframe super resolution techniques for the reconstruction of the reflected content.
Dubbed ‘webcam peeking attack’, a threat model devised by academics shows that it is possible to obtain an accuracy of over 75% when reconstructing and recognizing text with heights as small as 10 mm, captured by a 720p webcam.
“We further apply this threat model to web textual contents with varying attacker capabilities to find thresholds at which text becomes recognizable. Our user study with 20 participants suggests present-day 720p webcams are sufficient for adversaries to reconstruct textual content on big-font websites,” the researchers note.

Kännykkä ei enää kasvata kameramarkkinoita
https://etn.fi/index.php/13-news/14017-kaennykkae-ei-enaeae-kasvata-kameramarkkinoita
Parhaimmissa kamerapuhelimissa on jo jopa viisi kameraa. Tämä kehitys on kasvattanut CMOS-kamerakennojen markkinaa jo viimeiset 13 vuotta. Tänä vuonna markkinat laskevat 18,6 miljardiin dollariin eli 7 prosenttia viimevuotista pienemmäksi. Älypuhelin ei enää kasvata markkinoita, vaan kasvu tulee muilta sektoreilta.
IC Insightsin mukaan CMOS-kuvakennoja toimitetaan markkinoille tänä vuonna 6,1 miljardia kappaletta. Määrä on 11 prosenttia pienempi kuin viime vuonna, jolloin kamerakennojen osuus optoelektroniikan markkinoista oli yli 40 prosenttia.
Tutkimuslaitoksen mukaan CMOS-anturimarkkina pienenee, koska älypuhelimien ja kannettavien tietokoneiden kysyntä heikkenee. Viimeaikaiset Covid-19-viruksen aiheuttamat Kiinan tuotantolaitosten sulkemiset ja uusien älypuhelimien sisään pakattujen kameroiden määrän kasvun hidastuminen ovat syöneet kasvua. Useimmissa nykypuhelimissa käytetään kolme kameraa, yhtä edessä ja kahta pääkameraa takana.
