Can anyone suggest a utility that takes an audio file as input, and can output to a text/CSV file various data (RMS, peaks, dominant frequencies, etc.) per each N ms of the input, for both time and frequency domains?

Windows is my main target, but *nix as well.

It seems SoX has a few features in this direction, but not flexible enough (e.g., data per N ms, frequency domain resolution).

As a free alternative to MATLAB I'd suggest to try Python + Numpy/Scipy. I've never used it myself, but there is also a scikit for audio processing around.
