MQA is Vaporware

To the surprise of nobody, certain people were as pompous and abrasive as ever. I was told by people they’d never be on a panel or present with them again. 

 

Probably safe to say that Jbara is no pro at corporate governance, and Forsythe reacted poorly to his credentials being questioned?

To paraphrase The Princess Bride...

I'm well aware of the definition and I think the usage of that word is appropriate to describe your contributions to this thread.  Was that word an odd choice to use next to the word "futility"?  Perhaps.  But your message is clear: protesting MQA is futile and foolish.

It must not have been clear enough because that isn’t what I was saying at all. When you phrase it that way it sounds as if I think the success of MQA is inevitable. I do not. While I don’t share the animosity towards MQA that many posters here do, I don’t have any desire to have that be the only game in town. But the factors that will decide that are much larger than any thing that’s posted on this site. Apparently several of the more prolific posters here disagree with that sentiment. That’s fine. Carry on. 

 

Thanks for the response.  Am I imagining that you're avoiding the point I was trying to make?: you mock MQA protesters and certainly imply that their effort is futile and foolish.  Does your reply mean you won't do that anymore?

Hans Beekhzn also believes there are 3 unfolds, while 24 bit stops at around -144dB, so how is this graph even possible? It's a complete fabrication by HB (or copied).

So why is this completely incorrect graph still on Hans's site?

The article mentions "kwaliteitsgarantie" which means quality assurance, but the articles by Hans lack any quality journalism.

Let's use @mansr tools to educate him a little bit, shall we?

So he claims MQA can contain 4 resolutions, but he obviously is mistaking resolution and upsampling.

The first unfold can achieve 17/88.2 or 17/96
Then the second unfold can upsample to any value set by the orig_rate field as shown in the output of @mansr tool.

If your MQA dac does not support that resolution (e.g. you try 352.8 kHz but your dac is a 24/192 dac, it may actually try to use 24/176.4 instead), but that does not make MQA a format which contains 44.1, 88.2, 176.4 and 352.8K resolution in the same file format.

MQA is not DXD resolution, it can only do a fraction of DXD.

Also notice that MQA files have similar data rates independent of the original being e.g. 24/96, 24/192, 24/384 or 24/768 as it decimates to 17/96 in this case and tries to pack that in a 24/48 container.

For 44.1K multiples like DXD, you can clearly see the limitations of MQA:

Unfortunately, you are dealing with this:

It looks like to me Steven Stone is simply trolling you.  Hans however I don't think gets it - is that graph not straight from a Bob S presentation?

 

Sometimes you wonder if they are playing dumb just for sake of trolling:

or they are completely misinformed like the HB project

I suspect it's both.  I don't know who Steven Stone is but like so many doing audio "reviews" he might not have any knowledge of basic digital software at all.  He might not have liked being exposed so he is running with "perceptual lossless" and the like...

Hey MQA, if it is not all $voodoo$, show us the math!

He spilled the beans: he ignored all the independent research:
