I've just had a quick go at it, very little in the way of testing so maybe it'll be of help. Below relies on ffmpeg-python, but it wouldn't be a challenge to write with subprocess anyway.
At the moment the time input file is just treated as pairs of times, start and end, and then an output name. Missing names are replaced as linecount.wav
import ffmpeg from sys import argv """ split_wav `audio file` `time listing` `audio file` is any file known by local FFmpeg `time listing` is a file containing multiple lines of format: `start time` `end time` output name times can be either MM:SS or S* """ _in_file = argv[1] def make_time(elem): # allow user to enter times on CLI t = elem.split(':') try: # will fail if no ':' in time, otherwise add together for total seconds return int(t[0]) * 60 + float(t[1]) except IndexError: return float(t[0]) def collect_from_file(): """user can save times in a file, with start and end time on a line""" time_pairs = [] with open(argv[2]) as in_times: for l, line in enumerate(in_times): tp = line.split() tp[0] = make_time(tp[0]) tp[1] = make_time(tp[1]) - tp[0] # if no name given, append line count if len(tp) < 3: tp.append(str(l) + '.wav') time_pairs.append(tp) return time_pairs def main(): for i, tp in enumerate(collect_from_file()): # open a file, from `ss`, for duration `t` stream = ffmpeg.input(_in_file, ss=tp[0], t=tp[1]) # output to named file stream = ffmpeg.output(stream, tp[2]) # this was to make trial and error easier stream = ffmpeg.overwrite_output(stream) # and actually run ffmpeg.run(stream) if __name__ == '__main__': main()
