It is not currently as no one in the industry has reacted to my quest.@amirm , can you keep us updated on how the MQA music encoding effort is going? I think many people here and elsewhere are ready to contribute, myself included.

That would be fine too. I think @voodooless is citing 20/96 because it would be sufficient even by Stuart's own standards: 20 bits' worth of depth, plus a sample rate that permits encoding of frequencies at 26kHz (per Stuart's AES paper) and has a Nyquist of 48kHz (MQA's maximum).
You can't sell "20" bits to audiophiles who expect "24 bit" content. And you would be back to relying on dither to produce that although ways that could go wrong would be less.Indeed @lucretius is missing the point here. If the renderer only actually gets 20 bit resolution audio at best, then 20/96 is all we need to be on par with what MQA delivers.

Devil's advocate: "Why would you want 24-bits? That's 4 bits MORE NOISE than 20-bit. You don't want MORE NOISE do you?"You can't sell "20" bits to audiophiles who expect "24 bit" content. And you would be back to relying on dither to produce that although ways that could go wrong would be less.
Are you saying MQA delivers 24 bits’ worth of depth, or are you saying it’s okay for MQA to let consumers think they’re getting 24 bits even though they’re not?

That's too bad. Would it be crazy to call the nearest MQA-equipped mastering lab and ask how much it would take to encode a track or two?It is not currently as no one in the industry has reacted to my quest.
More devils advocate: I wonder what what the effect on FLAC encoded file size would be of sign-extending 20-bit PCM to 24? Seems it would compress pretty well...Looks like you can sell it.. it’s called MQA It’s just that nobody told the audiophiles as much. They could have made MQA with far less effort: just make a new file format derived from FLAC that uses 20 bit audio internally, and outputs 24 bit audio after decode. They could still add the magic bits to authenticate and control the renderer in the decode phase. But of course this would not have been a good story to sell.
I guess I am that one in a thousand MQA consumer with rudimentary spelling ability. And English isn't even my first language.99.9% of MQA consumers do not know how to spell '24-bit'. The rest are too busy with their crusades to enjoy any music.
Not if you fill those bits with 0's, rather that that pseudo-random crap.

Yes probably it would. But that way you’ll have to add dither after the decode to fill up those zeros.
Really? Presumably the dither was added during the re-quantization from the 24-bit master to the 20-bit encoding. Since sign extension doesn't change the value, the sign-extended "24-bit" samples would have the same value as the samples in the 20-bit encoding. So why would they need to be filled with noise (other than to obfuscate what you had done)?Yes probably it would. But that way you’ll have to add dither after the decode to fill up those zeros.
But never mind really, it was just a silly joke
20 bits is pathetic? It's only the limit of modern DACs...Yes. Pathetic.
Finally....That you’re a shameless annoying troll. Both in appearance and substance.
And it’s our tireless moderators’ job to deal with the likes of you. Or, often you guys just fade away in a couple of days, reaching your depth. So, let’s see.
They can't spell the word.do not know how to spell '24-bit
Your snark is getting a bit old and tired. Please try to be more pleasant in your attempt to belittle anyone who disagrees with you.Quite the opposite, sadly.
MQA will not encode high amplitude utrasonics, as they don't exist in music, at least with an automatic encoder.
Do you understand? If not, read the first word and see if you do. Proceed to the next word and repeat.
