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).

For the time-domain values, you could use something like this:
CODE
sox input.wav -n trim 0 0.012 stats : restart
(change 0.012 s = 12 ms into the desired block length). You are right, however, regarding the frequency domain; there is not much support for that.
