This question is also linked, IMHO, to one of the marketing options of MQA (talking about recreating higher frequencies), and one of the biggest misinterpretation on sample rate from 95% of people talking about sample rate :
- a thing that just extend the frequency range, but even if there's still a possibility that higher than 22.05kHz frequencies may be felt (I used "felt" and not "heard"), not necessary by your ears but, why not, by your teeth,... there are big chances that it has less chances to be felt than...
- the fact that higher sample rate = more samples, which by any logic, reduce the time between each sample and so should provide a "more fuild" rendering, closer to a live listening, and this the thing I see in only 5% of comments on Hi-Res files.
In this MQA case, where are and what are the intermediate samples in a first unfolded MQA file (from 24/44.1 to 24/88.2 for example) compared to the ones of a 24/88.2 FLAC file you get from Qobuz ?
This is for me the main question, more than the fact of having or not frequencies above 22.05kHz, even if they are linked.
In a 24/88.2 file from Qobuz, made from a 24/88.2 master, you get 88200 true samples each second, easy.
In an 24/44.1 MQA file made from a 24/88.2 master, you have 44100 samples each second, but from where come the 44100 other samples once the first unfold is done ? Do they are in the MQA information inside the file ? if Yes, do they are lossless or lossy ? Do they are interpolated samples ?...
This is the thing I would like them to explain, more than talking about having or not frequencies above 22.05kHz
