Thanks! I suppose one could read that as simply Bob wishing to capitalize on his data compression tech. HOW they go about it is certainly another thing, but yeah, "exploit" would be a suitable choice of words and intent in the current state of affairs.

I hear ya. Exploit just feels a bit different when used by this company.

If you want to feel even grosser, I present the text from a couple paragraphs down. The demand isn't there of course, and it will be created through favorable relationships. 

 

Where's the part about, our tech solves a major issue to which there is high demand, or even a little demand.

So sorry to hear Neil's music is no longer available on Spotify, as I've been using the service for over a year now!
Neil is one of my favourite song writers, so many great songs.
Oh well, I have almost all his stuff locally available, it's not a massive loss. But if I were to leave Spotify I'd not be going back to Tidal, that's for sure. There's always Qobuz as a viable alternative.

 

Thanks to Neil Young I stopped using Spotify and returned to Qobuz! So glad to be back to listening to high quality streaming and making much better use of my music system.

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. (although the article is unattributed)

I also spotted this one:

 

At the annual NY:LON event for music executives, Mike Jbara moderated a discussion on the values-based music economy. Joined by representatives from AIM, Family in Music and Sony Music Entertainment, the panel covered wide-ranging topics including diversity and transparency, as well as how the industry is responding to the issue of climate change.

 

Interesting, I recall delighting in Mr Jbara's moderating (maderating?) skills in a YouTube clip I watched covering an MQA presentation at RMAF back in 2018.

Yes it seems they are pushing the climate issue now with MQA seen as less than 10% of Tidals files are MQA and good slug of those are 16/44.1 (sorry 15/44.1) not sure there contribution is going to have much of an effect, have a word with Netflix and Amazon see if they are losing any sleep over it

It seems that older recordings,  recently available/distributed, the quality is becoming generally WORSE ... focusing stuff made since the middle 1950s when HiFi really started becoming HiFi, perhaps to the very early 1990s ... mangled with signal processing ... nastier, signal processing damaging the recordings ... 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.

There is so much mind power being used to create& market nonsense like MQA, ...  It would be best, of course, to simply 'master' while maintaing the most of the quality original recording. 

 

Agreed! I reject mQa's assurance of provenance as a way to tackle this problem. 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.  Similar point applies to this thread ["HDR Audio"].

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.

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?

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:

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:

081318-MQA_Decoder-600.jpg

 

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.

We are far more united and have far more in common with each other than things that divide us.

@John Dyson Maybe the new PGGB algo discussed/introduced here at A.S. is worth investigating for you? I don't have the DAC or compute power for it yet, but it's on my mind for the future of recordings such as you wrote about. 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.

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.

 

 

If this worked, as in sounded subjectively "real" in  most all circumstances, it would be amazing. I hear the ever so slight dynamic deltas between the addition of, say, a bit of silver in my cabling, but what I really want of course is for the dynamic range to bring the energy of the whole band/orchestra/arrangement coming in to punch me...well, more than it does now, which regrettably is "not much" as you note. 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.)

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.
