Hi Frihed.
We're not likely *ever* going to see a situation where you or I will have access to the encoding software for MQA. This is Meridian/MQA's trade secret sauce licensed to the music industry and folks like Tidal. Only people able to "authenticate" the sound will be able to encode into this format.
Of course the whole "authentication" idea makes no sense for Tidal! I mean, unless they just push all their hi-res and have it encoded into MQA, just how many songs can then they play in MQA at the start that has actually been meticulously "de-blurred" with information from the studio about the original ADC, DSP processing, etc. that could have affected the temporal domain!?

If they don't know the original adc they have a generic encoding that they can apply to any file

"Of course the whole "authentication" idea makes no sense for Tidal! "
Yes that it a correct observation. Tidal are not at the point in the chain where they can "authenticate" anything. It is the data supplied to Tidal by the original record company that can be "authenticated". Other tracks can be streamed in MQA without "authentification" as "authentification" is not mandatory, it's an option.
So although you are right in that there will be no consumer encoders, it is not the case that only those in a position to "authenticate" will be able to create MQA files or streams. Those streams will just not be "authenticated".
Agree PAR. I think you're right...
I don't recall what the claims would be for unauthenticated MQA like this though... Hard to imagine any kind of de-blurring in this situation. Seems to me at best they just do the data reduction with the lossy ultrasonic folding.

Admittedly, I don't understand the technology. However, as i tried to understand the commercialization, it did sound like it was based on the snake oil model.
Can't codecs be hacked? It happened to Sony years ago when they tried to protect their CDs from being copyrighted, as I recall.
