MQA is Vaporware

[Shadders]

Hi,

The challenge to MQA must continue. The general public are very unaware of what is happening. The media are not technically savvy to understand what has been discussed here in this thread. As an off-topic example of Windows 10 Telemetry :

 

https://www.zdnet.com/article/windows-10-telemetry-secrets/

 

States :

At the Full setting, you grant Microsoft permission to collect extra data when your device "experiences problems that are difficult to identify or repeat using Microsoft's internal testing.

The formal documentation makes it clear that this sort of investigation can snag personal documents:

This info can include any user content that might have triggered the problem and is gathered from a small sample of devices that have both opted into the Full telemetry level and have exhibited the problem.

However, before more info is gathered, Microsoft's privacy governance team, including privacy and other subject matter experts, must approve the diagnostics request made by a Microsoft engineer. If the request is approved, Microsoft engineers can use the following capabilities to get the information:

• Ability to run a limited, pre-approved list of Microsoft certified diagnostic tools, such as msinfo32.exe, powercfg.exe, and dxdiag.exe.

• Ability to get registry keys.

• Ability to gather user content, such as documents, if they might have been the trigger for the issue.

If you're not comfortable with granting that sort of access, make sure you turn this setting down to Enhanced or Basic.

 

So, Microsoft at the relevant telemetry setting has the ability to download to themselves your documents. Has the media published this capability ??? No, they are either not aware, or don't care - yet this feature is critically privacy invading.

 

The media do not ask the critical questions, and are severely limited in technical capability. So, MQA must be continually challenged.

 

Regards,

Shadders.

I was actually trying to be helpful by providing a link for you to read.  Now I see why you're on my ignore list.  I won't engage further.

 

Ever use Google?

Okay, that was a trifle mean of me, and I apologize for that. But seriously, I am sometimes humor impaired, and don't get jokes right. That's personally a little frustrating.

Later today or tomorrow I'll post a process with a "way around that."

Who hoo! Thanks Jud!  In that case, I will put this on hold and head out in the jeep for a bit of jeeping with my camera.

I've read more posts now from this thread (food for the brain, good), and I know that MQA has gained more and more ground in the last few years, being offered in many products and sources. It's almost everywhere now, except on analog vinyl and open-reel-tape. 

 

Bob Stuart seems like a reasonable businessman?  Forget the technology, the man, how people like the MQA additional sound, how they measure it, assess it, etc.; it is gaining more and more ground (streaming and all), and our children are living with it and their children will too until something else comes up as a higher level of audio business. 

 

 

 

It's a feature that many of us/them who are "digital heads" (way of speech) can't really escape unless they/we turn back or/and stay analog friends, with all the innocence of our youth. 

 

MQA is peaceful business, just like vinyl is, no? 

I'm not an expert I just like my blues raw and true and live.

Honest to God,  I cannot watch that for any length of time.  Does BS ever actually SAY anything?

[KeenObserver]

I forced myself to watch part 2.  BS was asked to comment on the fact that everyone was bringing up the fact that MQA was lossy.  BS stated that every DAC was lossy!   WHAT?

[KeenObserver]

Watching BS spew BS strengthens my resolve to resist MQA.  He knows exactly what he is doing.

However, no amount of "information" will help these folks because I can tell you from first hand experience, they are the most musically illiterate bunch you will come across, and they want one thing, which has NOTHING to do with performance or value, and that is status.

 

Painting with kind of a broad brush aren’t you?

I am pretty sure I understand how the MQA decoding is taking place, in pretty solid detail. 

 

 

Please share your findings and the method used to obtain this understanding.

I recently started watching Person of interest. You could replace the text at 00:23 by "Assimilating Music".
 

There's an actor with a striking similarity in this show.

Missed the smiley did you?   (It was a mild joke, though obviously, only a math nerd joke.)   -PR

 

What is your opinion on the filter? I have heard it on a 777, and thought then it sounded amazing. That was several years ago though, around 2012. [Edit, August of 2013 actually.]  A friend had that DAC and was so impressed with it, I actually traveled to go have a listen.  Did not buy one though. About the only DAC I would sink that kind of money into is a Wavelength.

Funny ... the iFi filter on the right
vs the SOX filter on the bottom, compared to "stock" minimum phase

 

So basically they implemented the MQA alike upsampling filter with one cycle of post-ringing.
 

I don't find this kind of filter very organic, Archimago's intermediate phase filter is far superior to my ears.

Yes this filter kills any MQA filters in terms of sound quality, and I decided to put it into our server, but you can configure it in any raspberry as well:

For search, I've been using solely DuckDuckGo for quite a while. It is actually better!

Good thing is that most browsers (except of course Chrome and maybe Edge) allow choosing it as default search engine.

GIS on right click has proven hard to replicate elsewhere.  Otherwise the current trend is using a stripped down offshoot of Bing.

Chrome 73 allows it.

Yeah, that would've surprised me.  I use Vivaldi, based on Chrome, and that makes it easy to choose DDG.  (I think they may have the execrable Bing as default, so I change it anyway.)

That's actually a screenshot of the PDF from iFi that was linked to earlier. If they used figures you produced, that's between you and them.

I don't really know much of anything about the GTO filter, have you looked at it or know who Gibbs is? 

I hooked the Nano up to the logic analyser and grabbed some data. It was more interesting than I expected. More tomorrow.
