I need a Linux tool to analyze Audio files for their Loudness. Maybe the average for each 100 milliseconds.

output like: (0=>-12,100=>-18,200=>-24,300=>-55) Any Ideas

I can give you a quick and hacky solution with sox that can be easily installed on any Linux distribution.

sox in.wav -n trim 0 0.1 stats : newfile : restart 2>&1 | grep 'RMS lev dB' | cut -d' ' -f 7

This will return RMS levels for each 0.1 second chunk. Change in.wav to the input file and 0.1 if you require a different frame length.
