MQA is Vaporware


Recommended Posts

I adjusted the volume of the Apple lossless up one "click" to compensate for that. Like I was saying, the person's ears told them that MQA was literally changing the music, by modifying the time alignment of sounds at different frequencies, and calling it "impulse response repair", in order to collect royalties. It's actually kind of amazing people have bought it hook, line, and sinker as a "repair" of "digital blurring" when, in fact, it's "repairing" musicians timing. Sigh. The songs used for comparison were Stressed Out and Jumpsuit, by the way.

Thank you for taking the time to do this. If your professional friend is willing to share any more impressions, they would be most welcome. I've been waiting for such a person to do something like this for some time. I had guessed that a seasoned professional would be able to take a good guess at what was being done to the music.

 

 

It's rather like tweaking a photo to make it pop I guess. It's very visible to me when people oversaturate the colours in photos to make them pop. Looks impressive to the untrained eye, but the experienced one can see it isn't representative of the reality.

 

 

If you want to kill MQA dead, you'd reverse-engineer whatever processing they were actually doing and make something similar freely available. Hence my comments on it sounding like it has been run in through a 3D plug-in. nycaudiolistener provided a better potential analysis.   Lately people have been talking about pre-upsampling music with software that uses a million tap or better sync filter. Why not something similar for people who want an "MQA effect" on any music they choose? Might require some serious programming effort though.

You're welcome! If you want to play with some unrelated, but rather advanced DSP, might check out Neural Mix™ Pro - Algoriddim and, in particular, the drum, bass, guitar, and vocals separation AI. Pretty impressive stuff! I suspect MQA was built using similar "black box" AI techniques, and MQA doesn't really know what it's doing to the music, exactly, either. Other than to say it is using that compressor / exciter concept, sidechaining it, and not questioning the results too much. More likely than not, this technique was borrowed from Meridian's DSP speaker line of products and repackaging into a file format. Anyway. Check out Neural Mix Pro for some fun times with AI!

But that amounts to the use of a different master, perhaps even a different mix, and is not an innate part of the MQA technology.

 

DSP is an innate part of the MQA technology. If your ears can't discern the rather obvious differences between the DSP that literally sits at the heart of the MQA remastering process (the outcome of which sits in a lossless FLAC file container) and plain old unprocessed Lossless FLAC (which also sits in a lossless FLAC file container), maybe you should rely on the opinions of people who can discern the differences. Respectfully. 

 

I mean, my god, look at Meridian's $20,000 speaker systems, that go on and on and on about the DSP used in the speakers. DSP is literally this company's core competency. The notion that MQA isn't using DSP to tinker with the timing of music is ridiculous. That's exactly what it does. Love it or hate it, that's what it does. I happen to like it. But, I am not living under any delusion that it's what they heard in the studio. It's not. It's "enhanced" sort of. If you like that sort of thing.

Front-of-house mixer. Live sound for artists at venues like Madison Square Garden. At age 23.


Great ears.

 

On an unrelated note, Neil Young is probably one of the few artists who has heard his own work in MQA. Most others probably don’t bother listening to their own work, in new compression formats. Have better things to do. Just my two cents..

If you want to embark on the very praiseworthy endeavour of criticising MQA then you'd better educate yourself on what exactly it does do and what it does not do, instead of muddying the waters. These things are not exactly a secret anymore.

 

Your allegations that the MQA codec itself wilfully tampers with macro-aesthetical properties of the music signal such as dynamics and imaging are evidently wrong. If such effects are observed then they are the result of additional remastering, performed concurrently with the creation of the MQA version.

 

Also you might do well not judging from afar the listening abilities or technical knowledge of people you don't know, people who have been studying this in detail since, oh, 2014.

 

 

I am sure the MQA cabal is very happy with noise sources like you.

 

Appears I pinched the nerve of some crank on the internet! You made my day! Lol.
