What I've done to evaluate the effect of bit rate reduction is to
take a fine example of nature sound (a bit of a Gordon Hempton CD),
transfer it digitally to an MD, then transfer that back, again
digitally, to PCM.
I can then do blind A/Bs between original and MD copy with my ABX
setup. No one has been able to distinguish the recordings yet. And I
can subtract the original and the encoded-decoded, resulting in a
difference file that is what the encoding took out. An interesting
experiment.
