[FFmpeg-user] Convert audio to CSV

[inhahe]

I don't know much about FFmpeg and don't know if it could make a .csv file
(it seems unlikely to me, but then, I've been surprised by how much it can
do in the past), but I would do it by writing to a .wav file and then
reading at converting the samples to C code in Python using the 'wave'
module and the 'struct' module, as in https://stackoverflow.com/a/5281240 .
If you'd still have to use CSV for some reason, Python has the 'csv' module.
