I know I'm late to this discussion, and there have been some good suggestions, so I'll just add this comment. I'd go with octave's (https://octave.org/) DSP tools and read the audio file into an octave matrix; it can read wav and aiff files natively (and possibly mp3, but I haven't used that.) You can then access any particular audio sample or group of samples, and use octave's version of the C functions printf or fprintf to write the selected samples to a csv (or any other) file, in whatever format (int, float, etc) is suitable. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
