What would you consider evidence? Emails between standards committee members agreeing to collude in order to screw pro-audio customers?
The evidence is: why on earth would anyone on a standards committee choose 44.1kHz, instead of 44.0kHz? The answer: 44.1kHz was transparently obviously chosen to make it impossible to perform on-the-fly rate conversions.
The mathematics of polyphase rate converters was perfectly well understood at the time these standards were created.
Someone else wrote that it was chosen to best match PAL and NTSC. IIRC there is also a Technology Connections video about those early PCM adaptor devices that would record to VHS tape.
4800kHz and 44100kHz devices appeared at roughly the same time. Sony's first 44100kHz device was shipped in 1979. Phillips wanted to use 44.0kHz.
If you can do 44.1khz on an NSTC recording device, you can do 44.0khz too. Neither NTSC digital format uses the fully available space in the horizontal blanking intervals on an NTSC VHS device, so using less really isn't a problem.
Why is 44Khz better? There's a very easy way to do excellent sample rate conversions from 44.0Khz to 48Khz, you upsample the audio by 12 (by inserting 11 zeros between each sample), apply a 22Khz low-pass filter, and then decimate by 11 (by keeping only every 11th sample. To go in the other direction, upsample by 11, filter, and decimate by 12. Plausibly implementable on 1979 tech. And trivially implementable on modern tech.
To perform the same conversion from 44.1kHz to 48kHz, you would have to upsample by 160, filter at at a sample rate of 160x44.1kHz, and then decimate by 147. Or upsample by 147, filter, and decimate by 160. Impossible with ancient tech, and challenging even on modern tech. (I would imagine modern solutions would use polyphase filters instead, with tables sizes that would be impractical on 1979 VLSI). Polyphase filter tables for 44.0kHz/48.0kHz conversion are massively smaller too.
As for the prime factors... factors of 7 (twice) of 44100 really aren't useful for anything. More useful would be factors of two (five times), which would in increase the greatest common divisor from 300 to 4,000!
You can download the entirety of Wikipedia. YouTube is blocking YouTube downloaders. It's a crime against humanity that they lured people into to contribute videos to this platform. By losing money for years before being acquired, they ensured nobody could possibly compete with their own video platform. Its not a nonforprofit or library. They can freely censor, restrict, and edit videos as they please, especially for deceased accounts.
I really hope this suceeds. I dream of a day where I can shop online and pay as conveniently as Chinese QR code based payment systems, but with full privacy.
I've followed GNUnet for years, and what inspires me about it is that it is the only project I've ever seen that takes the problem of The Internet is Broken[1] seriously and attempts to truely solve the whole issue instead of just addressing part of one layer like i2p and so on. Naturally, they bit off more than they can chew and it remains a research project with serious performance issues, crypto code quality issues, etc.
But out of GNUNet sprung GNU Taler which looks like it has a more promising future than even GNUnet it's self, since they have a prototype and have actually shown it to bankers.
If you happen to be a bazillionare, consider supporting these projects :) or if you're a banker, consider adopting the world's first consumer protecting payment system that extends the traditional system without providing a convenient vehicle for crime like cryptocurrencies.
Disclaimer: I'm not an an expert on anything, just a curious person.
Obviously yes to the first question. How could you possibly not have the right to operating your own heart.
Naturally it would generally not be a good idea.
I think this normalises running untrustworthy, abusive proprietary software, because they can at least be somewhat contained. The only reason I have apps like Facebook on my android phone is that I have sufficient trust in GrapheneOSs permissions.
Then, apps like syncthing become crippled as filesystem virtualisation and restrictions prevent access and modification of files regardless of my consent.
Not disagreeing with the need for isolation though, I just think it should be designed carefully in a zero-sacrifice way (of use control/pragmatic software freedom)
To me, I find it a bit frustrating that Arch linux routinely has "manual intervention required" problems every single year where the intervention is just a single command that pacman could have just ran themselves if they so desired. Sometimes, they get a new developer and you have to manually install their keys first otherwise packages fail authentication. What can you do in the face of that except conclude they don't want things to "just work" and create a derivative in the hopes of making things just work.
