PHASE R-L [z]


Roll-off above 16kHz is almost the same as for the 128ks/s test, and is a feature of the MP3 encoding, since tests using WAV files give a flat response to 20kHz out of the PUC. Artifacts on music will be reduced, at higher bit rate, but in practice 128kb/s sounds just about indistinguishable from the original, and is the best compromise to use.
