Comparing .wav samples from command line As a part of our project we should classify sound samples (stored as .wav files). All sample is the same, just pure speech (like a Skype test call). The process is the following: * a reference wav, this is the "high quality" sample * comparing approx. 1000 wav files * calculating divergence from the reference wav one by one Is there any Linux tool for that?

What I believe you are trying to measure (by stating _divergence_ ) is the **PESQ** , Perceptual Evaluation of Speech Quality, of each file. This is a standarized form ITU-T recommendation P.862 (02/01) <
