As 24 bit MQA files (not 24 bit of audio anyway, but 24 bit file format with more than 1/3 containing non nyquist data) can be truncated to 16 bit, and the MQA indicator stills shines on my Mytek, it's actually in the LSB bit of redbook. Depending on how you count, if bit 0 is the MSB bit, then it's the 15th bit, and this position does not change depending if it's a 16 or 24 bit MQA file.

Remember this block diagram? This is from the MQA patent. Notice the 'Lossy' parts? That means they are ignored and thrown away? Are you Dr. Frankenstein? Because that is what you are asking.... Thanks for this graph. The first steps are to noise shape the 24/96 to 17/96, and then all their folding steps to pack this as 24 bits at half the sample rate. Then the bottom graph shows the inverse process, where the output is 17/96 !!! I now have conclusive proof that MQA is indeed never any better than 17/96 The MQA shills are revisiting their canned articles ("research" they call this), but so are we.

" MQA produces music that is better than live. MQA corrects all the errors that are introduced in live music. Now you can hear music as it should have been played. MQA uses magic algorithms that correct the music to what the composer imagined." Kind of like "Perfect Sound Forever"? I'm pretty confident that even recording professionals who have had positive things to say about about MQA (people like Bob Ludwig, Peter McGrath, George Massenburg, Morten Lindberg) would cringe at Veth's preposterous statement. One of the things the pandemic has reminded me about the audiophile pursuit is that no technology is a substitute for the real thing. The musical organizations I patronize offer streamed performances in lieu of cancelled concerts and I find I have little interest. It's not remotely the same as being in the room with the musicians as a performance is happening. Hearing music live and perfectionist audio are complementary experiences—they always have been and always will be. So during COVID times, I listen more than ever to recordings that I chose at home while awaiting the day we can all return to concert halls and other venues. PeterSt and Currawong 1 1 Link to comment

By now I forgot how often that bits (or sequence of) sticks out its neck, but previously this was in bits 17-24 somewhere, which was part of the encoding scheme anyway, and deemed not to be in the Redbook representative. Now, however, it is really taken from the 16 bits Redbook bears anyway. This associates with HDCD. And guess what - in the long term HDCD does not sound right to me either. Maybe I must wonder whether there's a resemblance between the two. Maybe MQA Ltd hired KOJ ? Looking around, it's 13 bits for music data, 3 bits for MQA encoding. So, we drop back from 96 to 78 dB dynamic range ... is this a disaster? From my own experiments, investigating what happens when bits are lost - not really. If intelligent dithering is applied then what you get, subjectively, is an increase in benign noise - very large levels of gain are needed to actually hear this. No way is MQA-CD, er, good - but it's not the end of the world; if a release is only available in this then it still should be able to be made to sound good, 🙂. MikeyFresh 1 Link to comment

In the real world, of reversing audible 'damage', the difference is dramatic - going from "Get me out of here!!", to "Hey, that was a good track!" - worrying about the process being 'perfect' is in the realms of angels on a head of pin stuff - if it works subjectively, then that's what counts ... to me.

Should the justice department be looking into this? But in the legal sense that isn't what will be happening. There are multiple labels and MQA. Labels choose to have their catalog MQA'd, and then sell that version. In a legal sense this isn't a monopoly or lack of competition. The labels compete, and the non MQA material still exists. MQA hasn't eliminated it, the rights owners have simply decided to sell a certain version of their files and keep others in the vaults. Their prerogative. No case for stopping that. The fact that some audiophiles don't like the file version being sold doesn't matter. The labels can also choose to only make mp3 versions available if they wish.

While it's not a monopoly, I'd say the big labels make up an oligopoly. Seems to me that if they all release their catalogs in MQA only, then the big labels are conspiring together and acting like a cartel (non-competition). In any case, there's not enough interest outside the very tiny audiophile community, so there's no chance a government would intervene to break the cartel (and stop the MQA-only trend). mQa is dead!

FredericV Posted November 23, 2020 Share Posted November 23, 2020 On the group managed by Veter Peth, someone is comparing those MQA CD files with the ones before, and he does not hear any difference. As he is using an MQA dac, this would mean you actually need to use an MQA decoder in some form to get what you had in the past, without MQA. So the MQA tax is now active on Tidal: MQA adds nothing with those green fake 16/44.1 MQA CD files for the consumer, it takes away your rights and then sells them back to you as you now need MQA to get what you already had before. Maybe they come up with the lame excuse his system is not good enough ....
