RE: Read the link I provided

I mention Nyquest in an attempt to bound the discussion to reality. Inevitably someone will come along and say "Well Nyquest says...." and proceed to incorrectly cite Nyquist.

ALL digitization schemes lose some of the original audio content and the overwhelming majority of discussions of digital music are blind to this fact. The terms "lossless" and "lossy" are misleading. NO digitizing method records 100% of the original music.

In my work I use a 10 Gs/sec digitizing O'scope to look at 1 MHz waveforms. That is 4 orders of magnitude greater than the original waveform. I find it to be sufficient for my work even though some portions of the original waveforms are lost. To compare that to audio, the harmonics of some instruments can extend high 10's of kilohertz. Ignoring the mixing that will occur, to sample 4 orders of magnitude higher than 100 kHz would require a 1 Gs/sec sampling rate. I am not aware of any digitization method used for audio files that high.

Am I asserting that MQA is "good", or "sufficient" or excellent"? Nope. I am asking questions and participating in a discussion and appreciate your input.
