Subject: Objective Audio Quality Measurement
I wonder if there is a tool, a library , an application or something
similar which could help me to "find" an objective measure of the
quality of the audio without listening tests (i mean compare a
reference signal with a testing signal).
maybe the music-dsp mailing list is a better place to ask this.
Or comp.dsp.
I read ITU-R BS.1387 and some other documents about this problem,
and also tried "pqeval" but they seems incomplete and give
"strange" results ...
At higher mp3 bitrates, the difference is too subtle for objective
measures to be reliable as they are mostly designed for e.g. telephone
quality speech. And simple test signals don't tell you much because
the encoding can give better results with simple signals than with
speech or music.
