I have few wav files that I can use either of the following command line mentioned here https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20%28join,%20merge%29%20media%20files to concatenate
ffmpeg -f concat -i <(for f in ./*.wav; do echo "file '$f'"; done) -c copy output.wav ffmpeg -f concat -i <(printf "file '%s'\n" ./*.wav) -c copy output.wav ffmpeg -f concat -i <(find . -name '*.wav' -printf "file '%p'\n") -c copy output.wav anyone know how to convert either of them to work with python's subprocess module, it would be better if your solution is platform independent . -- https://mail.python.org/mailman/listinfo/python-list
