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) http://en.wikipedia.org/wiki/PESQ.
You have different projects implementing what you are searching for. For example https://github.com/imankulov/speex-quality-evaluation
