The following comment is based upon the assumption the bolded text is directly quoted from an MQA document. I might of missed where you expressly said it was. (EDIT: I now see where you did on re-reading after a cup of coffee!) Despite my personal objection to MQA, I saw the use of the word 'exploit' as no more than just 'monetizing' the IP and that reactions to it seemed a bit on the overly-sensitive side. However, the bolded text above reframes that perspective for me back in line with my contempt for the people pushing MQA in general. The statement "..... ensure that content is experienced in its original quality with an assurance of provenance." has, according to all evidence that I have seen, proven to be marketing hyperbole at best and outright lies at worst. Now that MQA knows the evidence is irrefutable, I view their obfuscation of this inconvenient truth evidence of their desire to truly 'exploit' the audiophile community in the most negative of manners.

Not sure I expect anything other than the latter (greediness) in the current climate. That said, I do expect the people who purport to work on behalf of the consumer's interests to be more altruistic. This is why I am staggered by the unwillingness of certain players in the audio magazine space (who have garnered such stellar reputations on testing products from an engineering perspective) to call out MQA based upon the preponderance of evidence. Self-interest and ego are the only reasons I can see for this failure. Maybe I am missing something or just simply naïve. botrytis, The Computer Audiophile, UkPhil and 4 others 7 Link to comment

Confused Posted February 5, 2022 Share Posted February 5, 2022 A recent review from the once great What Hi-Fi: https://www.whathifi.com/reviews/ifi-hip-dac-2 Here is an extract: And partly thanks to that chip, there's now full three-fold MQA decoding – a point that will doubtless pique the interest of Tidal HiFi subscribers. Thanks to the DAC's ‘three unfold’ decoding process, now performed internally (as opposed to just the final unfold in the manner of an MQA ‘renderer’ – the method undertaken by the original hip-dac), MQA files glow green but MQA Studio tracks are now recognised too, glowing blue. Magenta means the file is playing in its original sample rate (MQB). I can't quite believe anyone is still writing this kind of stuff.

(Wait, that's it! Put MQA on a blockchain with smart contracts to ensure royalties! That'll ensure provenance! 😉) Okay okay, back to audio; that's contentious enough. One frustrating thing is about all the MQA space in the market is being wasted on a big nothing-burger. I have been trying to find new material to test/listen to. It seems that older recordings, recently available/distributed, the quality is becoming generally WORSE and not better -- at best, just as bad as a few yrs ago. This is NOT about new recordings, but focusing stuff made since the middle 1950s when HiFi really started becoming HiFi, perhaps to the very early 1990s. There have been few recordings on a certain distributor's site that havent been mangled with signal processing. Out of the specific genre, I have found perhaps 2-3 acceptable recordings out of about 20. I am NOT including the signal processing vis-a-vis my personal project, but instead even more, nastier, signal processing damaging the recordings. One might excuse recent pop material which doesn't have or need great/natural recording quality. I am not looking at recent pop AT ALL. My focus is NOT recent pop material, but Jazz and 1900's American 'classical'. Just trying hard to find new, good copies. More and more often, It seems that there is too much processing going on against the recordings, sometimes against the older ones whose hiss doesn't need to be made worse. For the best listening experience, recordings should simplify back closer to the original mix. (Certain boutique recordings might be okay -- limited budget though.) Why am I mentioning this on this forum? There is so much mind power being used to create& market nonsense like MQA, where perhaps a more constructive and useful kind of signal processing would be a good thing. For example, it seems like more and more that 'remastering' actually means 'compressed to h*ll and back'. Since the world seems to want 'loudness wars' or 'demi-loudness wars' material, hows about some genius come up with a more gentle and natural sounding form of compression? THAT would be beneficial. Of course, I am assuming that the destributors strongly want to distribute 'compressed' and/or 'louder' material to begin with. (There ARE things that can make compression a little less ugly.) It would be best, of course, to simply 'master' while maintaing the most of the quality original recording. Without heinous damage, all you can get is a few dB of greater loudness. Of course, loudness wars stuff can give you >+6dB or more loudness, but why is it needed? We have so much SNR nowadays, the loudness is simply a waste. For me, it looks like it is time to look again through the used CDs in the various shops around town. Clean recordings appear to be more and more difficult to find. Why can't the rather bright person who invented MQA have developed something that actually HELPS music? MQA is sophisticated enough that the designer obviously knows something about signal processing -- what a waste. MQA is just a big waste and if anything, destructive. Continued pushback is important.

Just trying hard to find new, good copies ... For the best listening experience, recordings should simplify back closer to the original mix. Different CD instances of the same pre-1980 music leave me scratching my head - not just to discern the most listenable amongst them (weeding out "loud" instances easily) but also wondering which might be least messed-about-with as a digital master. Which is "closer" to the master tape. I may say to myself "the one I like" - or "the one that reminds me most of the analogue product". But who knows. 1 hour ago, John Dyson said: There is so much mind power being used to create& market nonsense like MQA, ...

Fundamental reasons already expressed all over this thread. Anyway - doubt there is sufficient market demand to produce what audiophiles of our kind want wrt back catalogue material.

FredericV Posted February 7, 2022 Share Posted February 7, 2022 The life of an mQa influencer: just repeat old articles. There's zero new research being posted. Just keep digging in the old stuff. And looking at the title of the original article "Zen & the Art of A/D Conversion", he missed the point. Why are there no mQa enabled A/D converters except for the Mytek? Quote Brooklyn ADC is the first commercially available ADC to feature built in MQA Kernel (TM) to be used for mastering to MQA streaming format. If this format was so revolutionary, all studio ADC vendors would want to add this feature. He clearly forgot to mention that this did not happen. Almost 3.5 years later, mQa still has no portfolio of mQa enabled ADC's. From the same article: Quote The music we enjoy never fully occupies a rectangular amplitude/frequency channel, which is one of the ways in which we can improve on the sampling process. This is once again about that flawed encoding triangle, which applies to most music, but not all music. Based on Bob's own research, the above claim is false, just look at the musicbox: Cebolla 1 Designer of the 432 EVO music server and Linux specialist Discoverer of the independent open source sox based mqa playback method with optional one cycle postringing.

Cebolla Posted February 7, 2022 Share Posted February 7, 2022 Also the diagram posted has nothing to do with the highlighted 'no such thing as an MQA filter', 'end to end', 'splines', etc nonsense and can only serve to add to the obfuscation with a 'pretty' (well he & the current 17 approvers think it is) picture: The irony that it only shows the structure of a full MQA decoding DAC, complete with the very real 'no such thing' MQA filter applying MQA Renderer is obviously beyond him.

I think I'll prefer that baked-in re-calculating solution to one that requires extensive tweaking of settings for real-time filters and transcoding. A different price to pay, I suppose. Thanks for the pointer... I did a check into what they are doing. It looks like mostly an optimum or nearly so EQ scheme. The 'decoder' that I am working on has VAST amounts of dynamic gain that undoes compression. It consists of many, many fixed filters and 8 gain control devices. The decoder actually *removes* noise and slightly enhances peaks. A fixed, passive scheme can certainly sometimes help also. *as mentioned elsewhere -- BOTH have their purposes.) The amount of work to do the passive EQ schemes can be done on a single core of a CPU, and with some left over. The decoder is lucky to run in realtime on a 4 core CPU running full-out. These are different things, each one has it's application. For example, the decoder has probably 100 2nd order EQs, and perhaps 100-200 1st order EQs, with 8 virtual pseudo DolbyA units each doing 10-15dB of gain control. The goal of the decode project is VERY difficult to achieve and perhaps the singular most difficult piece of software that I have ever been involved with. Back about 5yrs ago, I was offered a chance to emulate a Telcom C4 noise reduction unit after doing a plausible (now near perfect) DolbyA emulation, but those kinds of projects are not a challenge to me. (DolbySR would have been a challenge, but is too complex -- on the order of the decoder in detailed complexity, with very little benefit.) This damned decoder has been too much of a challenge, but it is getting closer and closer to success. Frustratingly, measuring the program objectively without specs, without architecture, etc -- has caused a lot of embarassment. Even my minimal objective measures to determine behavior are only approximate. (The measures must be driven by program material -- cant do it with a sine wave like a conventional frequency response measure.) Measuring frequency response/flatness is impossible using conventional techniques. The only reason why the decoder project hasn't been given up is simply because I have infinite patience, infinite persistence, and don't give up when starting a project. This is the reason why I got 'interesting' projects back at AT&T Bellr Labs -- I really try hard!!! Success is imminent, but even success wont' solve the problems with today's recordings, only those up to about 1992 or so. Thanks again!!! John Currawong and feelingears 1 1 Link to comment

Good luck and thanks for your persistence! Take a listen to the current snippet demos... Perhaps a version or two (perhaps 1 month) away from being professional/commercial quality. Don't listen for an extreme difference, but the difference between the original material is subtle, but very real (less hiss, more clean transients, tighter sound.) Currently, there is a bass problem where it sounds slightly 'stunted' (slight resonant bass at 20Hz, can be a bit irritating), and the very highs are a little rough. Solutions are known, just there are sometimes errors even in recent releases... The next release, with these problems fixed, will be in approx 1-1.5wks, and will be the final 'RELEASE5Final'. The project is very dependent on the reviewers/testers -- was clueless for a couple of years that my hearing has not been reliable, therefore caused a LOT of embarassment and some frustration, even by those who had been interested. It changed by >10dB at 10kHz and even below 100Hz throughout the day. The only thing that stable was between 200Hz and 2kHz (now taking steroids, which are really helping. Still, my hearing is not trustworthy. ) The design is based on standard values (+-3dB/+-6dB/+-1.5dB, standard freqs 25Hz,50Hz,75Hz,125Hz,... 3kHz, 6kHz,9kHz...27kHz,30kHz, standard Q: 0.577,0.8409, 1.19, 1.414, 2 - not 0.7071 ?!??!), very few 'tweak' values. Most tweaks (about 5 or 6 out of approx 500 EQ settings) are related to DolbyA type characteristics and the small differences between the DA decoder emulators and true HW DolbyA units. Here is the pointer to the demos (about 70 snippets) -- getting closer!!! I haven't announced these yet, but was planning to do so today anyway. Look for flacsnippet-RELEASE5F-V5.9.9G+8-0: (downloads are best, the dropbox online player sucks -- just be forewarned.) https://www.dropbox.com/sh/i6jccfopoi93s05/AAAZYvdR5co3-d1OM7v0BxWja?dl=0 Further discussion should probably be private (PM) or on the 'FA' thread -- I think that we all have great respect for this MQA thread, we shouldn't pollute it any further.
