  • Python, ffmpeg split list of audio files

    24 novembre 2020, par emil

    I know how to split one single audio file with python and ffmpeg :

    


    command = "ffmpeg -i a.wav -f segment -segment_time 60 -c copy out_dir/output%09d.wav"
command = shlex.split(command)
subprocess.run(command)


    


    For my current task, I have a list of several hundred .wav files I want to split.

    


    My current solution is :

    


    def parse_and_split_dir(directory, out_dir):
  files = [x for x in os.listdir(directory) if ".wav" in x]
  print(files)
  cntr = 0
  for wav in files:
    wav = wav.replace(" ", "\ ")
    temp_dir = os.path.join(out_dir, str(cntr))
    Path(temp_dir).mkdir(parents=True, exist_ok=True)
    temp_dir = os.path.join(temp_dir, "output%05d.wav")
    command = "ffmpeg -i {} -f segment -segment_time 60 -c copy {}".format(os.path.join(directory, wav), temp_dir)
    command = shlex.split(command)
    subprocess.run(command)
    cntr += 1




    


    I list all .wav files, and for each file I create a directory where I store the split files into. This implies that file naming start with index 1 for each new file.
E.g. folder 1 contains files ...1.wav to ...9.wav, folder 2 contains ...1.wav to ...13.wav and so on.

    


    In short, I ideally want to parse the whole directory with a single command, while keeping the naming continually from file to file, e.g. when the last wav saved its last split with ...10.split, the next split for the next file should be saved as ..11.split.

    


    I thought about first concatenating all the single files to one file, and then splitting them again (which introduces massive overhead), and unnecessarily consumes memory and disk space. An alternative I thought of was using a *.wav wildcard, but ffmpeg found no file called *.wav(which is expected).
