MQA Discussion

wklie said:
The Tidal service sends the original MQA streams in 24/48 or 24/44.1, not yet unfolded. The Tidal desktop apps perform the first unfold to 88.2 or 96kHz, but the Tidal mobile apps and browser playback do not.

This is irrelevant to people with MQA DAC, since they need the original bitstream to get the DAC to decode MQA. However, plenty of Roon users have been asking for MQA decoding because they do not plan to buy a MQA DAC any time soon.

Currently Roon Tidal users without MQA DAC can only listen to Tidal MQA undecoded. When Roon provides the first unfold, they can enjoy MQA decoded to MQA Core even with their non-MQA DAC.

Peter Thanks for the clarification. I forgot it was only the Tidal Desktop Ap that would perform the initial unfolding.
 
short version of that:

MQA … controversy …. business model … music business … digital … super audio … breakthroughs … dsp-active … niche market … satisfy only audiophiles is just not working … entire market … economics … ROI … steve hoffman … too little money …. mobile phone … everywhere … huge … dark side … yello … de-blurring…pre-ringing…major labels…total amount…contract...behind the scenes…engineering standpoint….millions of tracks…MQA-enabled software apps...controversy…audiophiles.

yes, that's good news. :S
 
But, but, but they won't listen to me about the evils of MQA!!

They only want to talk about how good it sounds.

Haha, funny.:P

Even funnier, when they "hear" how good it sounds with red book filtered soundwaves emitting speakers

and this type of physical reality:

True comedy gold. :D

You mean something like Soundfield loudspeakers? LMAO.

In that case I would stick to mp3 to be honest, can’t hear squat anyways [emoji15].

True comedy gold indeed.

And this gem:
When Jim Austin interviewed MQA's Spencer Chrislu for Stereophile in September 2016, and asked if he hoped or expected that all digital music will someday be MQA-encoded, Chrislu's response was blunt: "Well, that's the goal!"

Don't like unauthentic aliasing distortion laded music? Prefer DSD? Too bad!!

You've heard those too in your fantasies obviously :P.
Well, when only limited by imagination....

Well, actually never heard of them, there’s a mention in your profile. But there are a lots of these DIY guys claiming to be this or that.

So, therefore not part of my fantasies.

:lol:

The point here Kuoppis, is that your speakers, radiating into an actual room, will have far less >20k energy than you imagined. This is true for all loudspeakers, as very HF are quickly dissipated/absorbed by propagation through air and also the room surfaces....and especially true for "naked domes" like most audiophile speakers. That's what those LP measurements were showing.
The 2nd chart was the physical reality of hearing for adult males. Sorry, superheroes only exist in comics and movies. In real life, us mere mortal old guys all have HF hearing nowhere near 20kHz. Like it or not.:)

Btw, I'm an (albeit) small custom manufacturer, like many, former DIYer. That's why my site has prices and show reports , having exhibited many times. All totally irrelevant to MQA of course.

All fair enough, but analog LS output and digital encoding are two completely different pairs of shoes. Sure, both part of the same value chain, but even materializing in different domains. And remember, you are commenting on MQA here (encoding standard).

It is bemusing to see DIY guys like yourself throwing around all kinds of stuff, without the necessary scientific background, and mixing up things in the process.

It is also surprising, that almost 30 years after development of mpeg1/ layer3 encoding people still walk around uttering the same claims. You would expect a tiny bit of progress in three decades, wouldn’t you?

The logic in development phase was, that as part of the information is overlapping with other information, it is inaudible and can be taken away. This was good because it allowed for higher compression rates.

Today we all know, you can do that, but it sounds like junk. Since then data rates have been constantly going up again. You might also have noticed that Bob Stuart is not cutting away the inaudible high frequencies, he’s just placing them somewhere else.

Your ears can only hear the loudspeaker output. You can't run a digital cable to your ears. The only one that matters is the loudspeaker output, as I showed...with near Redbook HF response. This is before it gets to your ears and its inherent filters. Just so you are not confused.

You mean like you showing the impulse filter characteristics with an illegal signal and claiming you can hear it? :)
Once again, former DIYer. Formal education in EE, worked for RF company, now in Civil Engineering. Careful throwing stones about scientific literacy when displaying zero. Might become really bemusing. :D

So you are admitting MQA is just another lossy compression scheme, even with your lack of understanding of what MQA actually does. Cool.
The bottom line is if you enjoy aliasing distortion laden lossy unauthentic music, you are perfectly entitled to do so. I and others have far higher standards for fidelity and don't want that forced upon us, as they are now openly admitting to.

Oh boy, this is even more challenging than I figured.

Are you saying that it does not matter what even gets to the LS, because the LS is all you can hear? How do I explain this...

On that scientific basis, I wish you best of luck with your DIY speakers.

I just leave it at that.

Please do. Explain what happens to your 40kHz that "gets to the LS" here:

Unless it's the same as the illegal signal? Your eyes see it, your ears "hear" it?

Nope, didn't say that. Just your imagination again.

My mother?? Wow, very mature. You shouldn't type such stuff with your small orange hands, it reflects poorly.
I'll leave it at that.

MQA is going to be a subjective decision, but obviously a lot based on belief, much of it marketing nonsense.

Uh huh. So says Mr. DIY [emoji3].

I bet you have neither read, nor would you even understand the patent filings or even comprehend in the first place that you would need to study them to be able to pass judgement.

Except of course I did...and discussed in detail on other sites :)
You're projecting again.
Now, care to explain what happens to "unfolded" 40k signals at those loudspeaker terminals? Or how you manage to hear illegal signals you saw?
