Michel Rouzic wrote ARSS (Analysis & Resynthesis Sound Spectrograph) and maintained it through 2008.

The ARSS project page says "ARSS is now superseded by Photosounder", his non-FOSS spectrogram editor.

This repo is a fork of ARSS 0.2.3.

Building

cd src; cmake . && make

Examples

(mono WAV) → (spectrogram as raw 32-bit float matrix columns)

cat foo.wav | ./arss-fork STDIN STDOUT --min-freq 500 --max-freq 20000 --height 100 --pps 100 --analysis --float32-columns > foo.matrix

Changelog

0.3 : 2010-09-28

• Support for reading from/to STDIN/STDOUT
• Alternate output format: raw 32-bit float matrix columns.

Notes

("STDIN","STDOUT") used instead of ("-"/"-") due to the original project's option parser.
