Yes. What my concern about this is is actually the lower and higher frequencies in the mp3s. With these the loss was neglectable. I thought preserving the full range and quality was paramount with audio testing, but I'm not an expert or an audiophile, it was just my preconception. (Listening to an original .wav song with my headphones and then an mp3 of 192 or 320 kpbs quality, the difference seems obvious, but mostly at the low- and the high-ends.)

For most things, yes. There are some sounds that do not compress well, however. Harpsichords and trumpets in particular are pretty noticeable.

This is probably a failure of the major algorithms rather than a damnation of audio compression in general. I imagine even they will someday be basically imperceptible in difference.

Right now, though, I can score 100% on a blind ABx test on most horn instruments =\

Haha! Thank you! I wasn't paying enough attention (or not enough coffee).
