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).

Another alternative might be Praat, that has basic scripting capabilities and allows to easily extract low to mid level audio features.

No, I'm not aware of the specifics of SciPy/NumPy. Sounds like the plot thickens, at least with shared webhosting.

I also wasn't aware initially of SoX's restart command.

Praat is intriguing. I wonder why they seem very intent on not showing any screenshots in their site. smile.gif
