MP3Pro didn't do that well in a public double blind listening test done by the
German c't. Ogg Vorbis came out 1st at 64 kbit, and plain MP3 last.
At higher rates things were much less clear; people started to confuse a lot of
the compressed material with the uncompressed.
I remember that at 64 kbit there also was some confusion between Ogg and WAV.
But th edifference is clearly audible, but more of a stereo imaging nature than
something easier to pinpoint.
Ogg is variable bit rate by the way. See
http://www.xiph.org/ogg/vorbis/index.html . Free to use for any purpose, no
license fees apply - neither coder, decoder, hardware or software.
Takes a bit more CPU than MP3 though.
For the c't result in German:
Translated quote: "especially at 64 kBit/s, Ogg Vorbis excelled and left the
whole competition behind. At and above 128 kBit/s, the niticeable differences
between formats are smaller, and WMA, RealAudio, MP3Pro and also MP3 were hard
to distinguish for most ears."
