So, did Brink get banned? Can't believe he hasn't chimed in here.

Hi jhwalker,

I am rather unsure when exactly they started with development (considering they filled the patent in Dec-2013), however broadband 20Mbit+ dedicated fibre is a reality in most Eastern European countries since 2007. I had my 100/100 connection installed in Nov.2007 which should have no problem streaming 4,608 kbit/s for stereo 24/96.

As far as mobile data, where to this day (unless you're on unlimited data plan), you pay for every MB downloaded, MQA 24/48 container isn't really helping the situation much, in non-urban areas, you might be lucky to get 10Mbit/s on B20 LTE band (EU allocation), and yet the 10GB data package would be done for in just few albums. 

 

Opus should be the way to go for streaming IMHO. Personally, I don't stream at all - keeping everything local has its advantages when network drops out. ;)

 

I think we're saying the same thing - I'm sure MQA has been at least 10 years in the development, probably more.  It's a case of taking so long to get to "production" current events have rendered your product obsolete.

 

Of course, I came "of age" before personal computers were widespread (and certainly before the Internet was publicly available), but I remember in the early days of the Internet when tiny (postage stamp sized) "videos" on websites took minutes to buffer so you could watch them.  Last night, we watched one of the latest movies in Blu-Ray quality streamed (flawlessly) with no initial buffering whatsoever.  Amazing what a few years' progress can do!

In fact what's happening is technology becoming more available. 

You could get FullHD capable transport in 2002, 12bit CMOS sensors in 2005, etc. The technology was there, only difference being it wasn't mainstream and cheap like it's now. 

 

Yep I remember those tiny Quicktime-based preview videos on webpages that took ages to download (through high speed 56.6kbps of course). ^_^

 

I can't see myself switching to streamed music anytime soon (5+ years) for portable use. Just the level of complexity it requires, somewhat feels redundant compared to local storage. But to each their own. 

Another point to consider when going outside is the ambient noise level, which in most urban environment won't go below 40dB SPL. Rural areas (especially at night) are much better in that aspect (avg. 6 to 20 dB SPL on my favourite spot B|). In the city, even 16bit lossless streaming while mobile is really pushing it IMO. 

140kbit/s Opus would work wonders in that setup.

Certainly not. There is very little of substance in MQA, and the origami ultrasonics folding idea already existed in Japan. I am certain that from the first bright bulb idea to a proof of concept prototype in software did not take longer than a few weeks.

 

If they spent a real effort, it was in politics and lobbying.

You omitted a fourth possibility: that the magazines' writers honesty report what they hear.

Possibly... But I have listened to a lot of MQA (see my signature for my system, and it is very carefully set up) and I can tell you some is good, some the same. It is not a panacea or anything of the sort espoused by the audiophile press. Come listen if you like, I live in Chelsea, NYC.

He announced he wouldn't be posting any more and might return at a later date under a new userid.

The forum would be a much better place if everyone were less convinced of how right they were.

Oh yeah, you're right. Thank you. 

 

Maybe the MQA gang made Brinky an offer he couldn't refuse...

As always Archimago, your objective commentary rings true. Nice to hear commentary and clairvoyance on this topic. Thanks again. I think most of us want full PCM content streamed, until that point hits fruition then MQA Tidal  is still the high point in streaming audio. However Lossy MQA mastering is, it does provide a pleasant sonic experience on most content,  particularly older analogue  music files. As bandwidth expands, I think most audiophiles want to experience the original, as recorded format in the highest original format. The industry should give not give MQA the end game in content provided. Hopefully you insights will become mainstream.

Given their history, should we as consumers trust anything the big record companies (industry) are doing in regards to MQA?  I think we should be very cautious.

I’m more concern that the DACs we buy today especially MQA ones may default to MQA filters(for whatever reasons) when playing back non MQA contents. It is through technical testing one can see the effect of aliasing and distortion patterns here. There’s no tool at the moment to access MQA encoders other than the music companies themselves. Because of this, it is difficult to fully test an MQA DAC without generating a test signal from the encoder. The only test at the moment rely on MQA music contents.

DSD and PCM have long been able to qualify technically with test signals for each hardware release from the manufacturers. This guarantees high standard of specifications and the rest is just listening.

After reading this great article and much in dept technical details I found a similar conclusion on 6moons which also describes a way how to do without the MQA encoding and avoid their filter

 

It is published in the Keep it Honest chapter in cooperation with John Darko.

This screenshot shows the average technical knowledge level inside the secret MQA group:

"Archimago is quite good, but he really does not understand how MQA works."

 

-> please buy a mirror

This guy does not even understand the basics of sampling.

The same clueless members continue to claim the MQA train cannot be stopped. This is a very recent screenshot.

Our CA frontpage article was also deleted from the group.

I don't have a membership in the group, so they now must find their mole ....

Ah .. I did not realize this ;-)

 

It's a small world after all ... haha.
