Here are some audio and video trends for 2018.
Buying headphones in 2018 is going to be a fragmented mess because of a silent goodbye to the 3.5mm audio plug, Majority of new headphones introduced at CES were wireless and there are several different wireless systems. Bluetooth audio has historically sacrificed sound quality for convenience relative to a wired connection. However, there are a couple of standards now that promise “better-than-CD” audio quality. For wired connections where we once had the solid reliability of a 3.5mm analog connector working with any jack shaped to receive it, there’s now a divergence of digital alternatives:Lightning, USB-C, and Sony’s 4.4mm Pentaconn connector.
Voice, connectivity and AI took center stage at the Consumer Electronics Show. Alexa Skills and the Voice Experience is really getting off. With over 15 million Amazon Echo devices shipped and 244 million projected by 2022 it is expected to take lead with Google Home Assistant and Apple Homepod with Siri following. Also Google Assistant was mentioned a lot in CES. Google Sold 6.75 Million ‘Google Home’ Devices In the Last 80 Days. ‘Language assistants were a big topic at this year’s CES. More and more manufacturers like JBL and Creative are integrating smart helpers into their WLAN speakers. Alexa support comes to 2018 TVs from Sony, Hisense and LG. Google launches smart displays with JBL, Lenovo, LG and Sony. There will be also other competitors aiming to this market, for example “China’s Google,” shouted out most loudly for voice. Microsoft’s Cortana had a crappy CES so it seems that Amazon Alexa will soon arrive on Windows PCs (HP, ASUS, Acer and others). Introducing Single-Chip Solutions for Building Alexa-Enabled Products.Sony launches a bunch of new headphones and adds Google Assistant functionality to the line.
Binaural, ambisonic, spatial, surround, 3D will be talked about. The most accessible exhibitions of this technology are in Youtube VR and Facebook 360, where users can interact with 360º videos that contain spatial audio. AR/VR was hot topic at CES 2018.
Sound bars are popular for compact home theater setups. Traditional home cinema systems with AV receivers and large speaker arsenals are only used by film and sound enthusiasts who sacrifice space in the living room for this purpose.
People listen to four hours of audio content every day. Streaming platforms like Spotify take a big bit of that. Streaming accounts for 41% of music consumption was the 2017’s most jaw dropping statistic. People will also listen a lot of music from YouTube.
Acoustics-based NFC is being pushed to market as it requires only a microphone and speaker, eliminating tags and chips. Chirp and LISNR are two emerging companies facilitating soundwave communication.
Wireless headphones and speakers become more common. Portable loudspeakers without cables are more popular than ever with music listeners. Most popular connection technology is Bluetooth.More and more manufacturers are breaking away from the cable and are showing new models and updates of completely wireless in-ear headphones at the CES 2018.
There is a bit of nostalgia involved: Several traditional technology tries to make come-back in 2018. The traditionalists among the music lovers continue to use records, so new record players keep coming. Cassette tapes making a comeback thanks to young, independent artists. Artists like Justin Bieber, Eminem and Metallica have all put out material on tape recently as a recent blockbuster film “Guardians of the Galaxy” put a hero center stage with a Sony Walkman. Tube amplifiers are back for traditionalist audiophiles that think that tubes can make your music to sound better.
4K video resolution is hot and 8K going to be pushed to market. TV has progressed to the 4K ultra-high-definition stage with its 3,840 × 2,160 pixel resolution. LG Display has made a 65-inch rollable 4K OLED TV. LG displayed 8K OLED TV at CES. Samsung has technology scales the image resolution to a 8K with AI. LG, Panasonic, and TCL put the spotlight on the chips that do the video processing: For the foreseeable future, any advances in image quality will be coming from these chips, not from the displays themselves.
Welcome ATSC 3.0 in USA: In November, the Federal Communications Commission (FCC) issued new rules that will let TV broadcasters adopt the next-generation wireless TV standard designated ATSC 3.0. This new standard defines the specifications for ultra-high-definition (UHD) or 4K over-the-air (OTA) digital TV. But over-the-air is minority in USA as roughly 75% of households pay for their TV reception for cable or satellite distribution.
Home theater headsets have come a long way. AR/VR is hot. Oculus partners with Xiaomi to launch the Oculus Go and Mi VR Standalone.
Wired peripherals and electronics are still a major part of the market. Cabling for AV systems will have new features: a new HDMI standard and how active cables will provide both power and video to consumer devices.
3D cameras are hot. HP’s Z 3D Camera puts Sprout’s scanning power on your PC. Intel’s new cameras add human-like 3D vision to any machine.
When almost all AV products are pushing more and more features, it seems that almost Everything is too complicated for an average Joe.

How to Make a Night Vision Camera From a Regular Digital Camera (Infrared IR)

How to convert a digital camera into an infrared night vision camera. I needed a camera that could film in the darkness of night whilst doing astronomy, so I converted this old snappy to be able to see infrared light. It works a treat!
Comment:
Older cameras and most cheap Chinese cameras don’t have IR filters. Easiest way to tell if your camera isn’t filtered and can see IR is look through the camera at the front of a TV remote and press some buttons on the remote. If you can see the red light flashing then your camera isn’t filtered.

Recording Sound to DSLR Camera vs Audio Recorder
https://www.youtube.com/watch?v=2oZp_k7AmXs
How can you get the best quality sound for your videos? There are a lot of factors, and using an external microphone is one of the big factors. But another question that comes up quite often is, will a dedicated audio recorder improve my sound quality? I think it will in 95% of cases. Here’s a sample comparing the quality you get with a professional level lavalier microphone, the Countryman B6, recorded into a simple Zoom H1 audio recorder and recorded into a typical DSLR camera, the Nikon D750.
Now there are still cases where recording sound with your camera may be good enough. But if you want the best audio quality you can get, even a little $99 USD audio recorder is better than a $2000 DSLR camera.

NAMM 2018: CONTRASTING PHASE, ORTOFON, AND RANE’S TWELVE
https://djworx.com/namm-2018-contrasting-phase-ortofon-ranes-twelve/
Vinyl is a beautiful, if inherently flawed medium. Who thought that it was a great idea to have a literal industrial diamond scraping plastic to recreate sound? We have lasers, touch screens, etc, but we still cling to a medium created in 1886.
This NAMM had three different approaches as to how to modernize the art, embracing the lineage while moving toward the future.
Phase is interesting in that it is not a new idea, but the execution is such that it fixes many of the issues with units that came before.
Can THIS change everything?

$60,000 for our stolen photo: We made a copyright thief PAY!
https://www.youtube.com/watch?v=DUEbi4r8Pg0
Two years ago a company used one of our most well-known photos on the cover of an iPhone case without our permission. This was misleading in a couple of ways; the product seemed to advertise that it could produce the results in our picture (it couldn’t) and some people assumed we were endorsing the product. The product was in some of the biggest stores in Australia and New Zealand, including Target, and selling for about $70 AUD.
We tried to reach out and handle it nicely without getting lawyers involved, but the people who stole our photo immediately lawyered-up and tried to ignore us.
So we sued them. That wasn’t easy!

Raw vs JPG: Image Quality vs Speed, when to use each
https://www.youtube.com/watch?v=QczEFjn9P7I
Summary: Raw is better for image quality, but JPG files are quicker to shoot and process. Raw is the right choice for most photographers in most scenarios. I almost always shoot raw or raw + JPG. JPG might be a better choice for photographers taking a large number of pictures or those with limited storage.
The main point Jared and many of his followers seem to be missing: Raw might be right for YOU all the time, but other photographers have different cameras and shooting requirements. SO MANY parents are shooting their kids sports with a T6, which buffers after only 6 raw shots, and takes several seconds to clear. Shooting JPG will reduce the buffering.

Why the Film Lab of the Future is Open Source
https://petapixel.com/2019/01/09/why-the-film-lab-of-the-future-is-open-source/
We are approaching the peak capacity for film photography labs. The machines are old, the parts are scarce, the demand is high. The measly Kodak Pakon Scanner, terrible it may be, fetches absurdly high prices.
The two brands and workflows that need to be replicated are Fujifilm and Noritsu. A theoretical duopoly, but here lies the problem: Fuji is dead. When will Noritsu follow suit? All the remaining hardware is on life support, waiting to die. The state of the film lab is much the same as the state of premium compacts of the 90s.
The solution is inevitably open source, some sort consortium between photo labs and other interested parties on a commitment for free and libre IP on parts and technology for scanners/processors. “Free as in speech, not beer.”

What’s the difference: High-end audio & audiophile?
https://www.youtube.com/watch?v=9di4HiyUKzQ
Some people use those terms interchangeably, but they’re different.
Comments:
High end is the selling of “money” over quality. The idea that something that costs X amount times the cost of something else, it must be X times better.
That’s not the case. It’s prevalent in the electric guitar industry where the big name companies use their brand name to overcharge for their goods.
I agree that affordable high end audio is the way to go.
I agree and a lot of High End Audio made for the super Rich and Wealthy is perhaps more of a piece of ART rather than being that much more superior in sound quality.
I don’t know, what is the difference between gourmet, handcrafted and artisan sandwiches? It is a stupid play on words to be the more serious or better class of something for marketing. It’s a stupid linguistic game.
How about this. All High End is Audiophile but not all Audiophile is High End.
He’s definitely saying that not all high-end is audiophile. It shows if you read enough reviews

SuperTweeters: how to increase your frequency response or a critique on modern music compression
https://www.youtube.com/watch?v=lGeh-PLySGE
In this video we analyze the benefits of introducing a pair of SuperTweeters in out Hi-Fi system and discuss the issues related to the over compression adopted in modern music recordings and media
Comments:
Well done, great video! Very interesting, and enjoyable.
your supertweeter also produces sound under 20khz, still down to 10kHz and this interferes with the normal tweeter output. The normal tweeter also produces output above 20kHz because it is only highpassed. So you DESTROY your sound in the hearable range with lot of interferences . That is really bad. Use a frequency filter for the supertweeter and integrate the loudspeaker tweeter in this filterdesign. But this is all useless. Please concentrate on linear frequency response in the hearable range from 35Hz to 12 kHz!

If a Photographer can do THIS with an Entry Level Camera, What’s Your Excuse
https://www.youtube.com/watch?v=Lh-zcxqFkGA
How many times have you heard “my camera stinks” or “I need a better camera”? As I have said a million times it’s not about the camera as much as the lenses. And in many cases you can get better pictures with an entry level camera with a solid lens than the best pro camera with a crappy lens.
This set is another example of someone using an entry level Nikon D3200 and coming out with poppy vibrant color and black and white images. On top of that their composition is top notch and the subjects are interesting.

Why do cheap audio cables usually get the colors reversed?
https://www.youtube.com/watch?v=x5oh713ca38
You know what really grinds my gears? When audio cables (or even A/V cables) get the colors reversed. Especially with cheap cables from China, it seems to happen more often than not. And I’m not the only one experiencing it:
Caution! Non-standardisation in audio interconnects – left/right channel reversal
https://www.harbeth.co.uk/usergroup/forum/subjective-soundings-your-views-on-audio/electronics-sources-stands-cables-accessories/cables-connections-biwire-links-discussion/1010-caution-non-standardisation-in-audio-interconnects-left-right-channel-reversal
On a number of occasions over the years I’ve been aware of a Left – Right signal reversal. Using pop music as a test source, it’s impossible to detect this reversal because there are no rules about which instruments should occupy particular positions across the L-R sound stage.
But for classical music, with rare exception, the musicians are arranged in a rigid plan from left to right, just as you would hear them in the concert hall playing a contemporary western symphony or similar*. It beggars belief that a commercial CD could be mastered with L and R transposed, so what is the problem?
It seems that the issue is that many – perhaps most – 3.5mm jack to L – R phono cables are incorrectly wired inside or colour coded outside. There is a perfectly clear standard of how the unbalanced stereo three-way jack plug should be connected and it is the top picture here. The tip (marked 3) should be left channel, the ring (marked 2) right and the body (marked 1) the common ground. But the tip and ring connectors are frequently interchanged.
According to Pro Co Sound (who bulilds audio interface products) – Engineering Specifications states that the colour code for hot is red and for cold is black. If the tip is hot then red should be hot. Maybe, this is why you find longer cables to be “miswired” because they were probably used in recording industry rather than home audio where red is right and white is left.
According to their standards:-
Audio signal wiring typically involves three connections:
SHIELD a/k/a common, ground, screen
HOT a/k/a high, positive, phase
COLD a/k/a low, negative, antiphase
In general, Pro Co regards a red conductor as HOT and a black conductor as COLD, and wires all connectors to accepted industry conventions:
• Two-pole connectors (1/4′ phone, 3.5mm mini, RCA phono, etc.): HOT conductor to tip, COLD conductor and SHIELD to sleeve.
• Three-pole connectors (1/4″ phone, 3.5mm mini, ‘TT’, etc.): HOT conductor to tip, COLD conductor to ring, SHIELD to sleeve
STORY SO FAR: Even the audio industry cannot (seemingly) decide how to connect a 3.5mm jack plug to two phono plugs. You MUST be on guard for channel reversal.
The final arbiter of this must be an IEC standard or equivalent.
It appears there are two color codings for 3.5mm Jack (TRS)to RCA cables. One is Red and Black, and the other is Red and White. My headphone’s 3.5mm to RCA cable is Red and White. The red colour is for right channel and the white is for left channel.
I have another set of cables but that is Red and Black and here the Red is Left channel. I only realized that after reading your post. All the while I was thinking there was something wrong with my computer’s sound card.
Did you find the case of wrongly wired interconnects only applies to Red and Black RCAs? My old RCA interconnects were Red and Blue colours.
Unfortunately, it’s all too easy to disprove this theory and I am unshaken in my original position which is, regardless of whether one considers red and black to be right and left or red and white to be right and left there is no assured consistency across cables regardless or brand, length or any other factors. There is complete chaos over this rather small, but important point. You cannot and must not assume that the tip is wired to a particular channel whichever ‘specification’ you chose to believe in
Enough proof? You have to ask yourself, if the audio industry can’t even get this most basic issue of left-right channels correct, can you believe anything you read other than that from real, hands-on end users?
Or you can just buy/borrow/steal/download a Stereo Test Disc, like Stereophile’s Test Disc 2, which includes channel separation and phase tests. Both should indicate whether you’ve got cables that are faulty or cables that were mixed up by the user on initial connection. HTH.

Wireless security cameras overcome ‘glitch’ fears
https://www.electropages.com/2019/01/wireless-security-cameras-overcome-glitch-fears/?utm_campaign=&utm_source=newsletter&utm_medium=email&utm_term=article&utm_content=Wireless+security+cameras+overcome+%E2%80%98glitch%E2%80%99+fears
Wireless security cameras are rapidly becoming more sophisticated with the latest models now equipped with motion detection sensors and the ability to record footage of an intruder. More advanced cameras include facial recognition and two-way audio. But regardless of the model, it is the quality of the video footage that is the most important aspect of a wireless security camera.
All security cameras support at least 720p resolution (1,280 x 720 pixels), although this is now giving way to 1080p (1,920 x 1,080 pixels). The ability to switch seamlessly between day and night modes and pick out the same level of detail even in low light is a pre-requisite for any good wireless security camera. Night vision enabled devices may use either: LED lights, infrared, or a combination of the two. Cameras with motion detection sensors usually have the ability to send alerts to a phone app or via email. It is also possible to set up a schedule whereby motion alerts are enabled only when the customer is out of the home.
Cameras can either operate from the mains plug or from a battery.

I recently changed out some poorly made xlr to rca connectors to cables made with much better quality. And it made me wonder: with such a difference in quality, will the sound also be improved? In this short video we’ll find out.
Comments:
I’m hearing no difference. I don’t claim to have expert hearing but on a similar note: Lifehacker did an experiment on MP3 bitrates and the conclusion was: Listeners typically can’t tell the difference between bitrates above 128 kbit/s. I think something similar is going on here.
Almost exactly the same from what I could hear on my okay PC speakers (maybe my monitors would make the difference more obvious),
Now everybody will say that B sounds better simply because you said it was the most expensive cable… personally I heard no difference between the two

Color isn’t what you think.

Most people think that “color” has nothing to do with luminosity (brightness,) but it does! The correct word for that is “chrominance!”
Here’s the paper I’m citing:

In regards to computer monitors, CIELAB would be an absolute color space if a white point AND a white LEVEL were defined, but it’s not, so it isn’t.

Netflix thinks ‘Fortnite’ is a bigger threat than HBO

Netflix thinks “Fortnite” is a bigger threat to its business than HBO. The company in its latest quarterly earnings report released on Thursday said that while its streaming service now accounts for around 10 percent of TV screen time in the U.S., it no longer views its competition only as those services also providing TV content and streaming video.
“We compete with (and lose to) Fortnite more than HBO,” the company’s shareholder letter stated.
