This is a test of MP3 quality using RealPlayer to make the file from Lindos CD2 and then play back via Yellowtek PUC USB 'soundcard'

Good noise and dist but note the 11kHz rolloff. This appears to be the same performance as the basic free RealPlayer.
The CD can be considered 'perfect' as it was made using noise-shaping from 24-bits. The noise out is that of the PC convertor used for replay. MP3 encoding has not been found to add noise to the original.
