[Bug] extracting few audio files in same time about just_waveform

[ryanheise]

That could be a good idea, although I doubt it is a good idea to be decoding multiple files at the same time since it is very resource intensive. Why not decode the files one after the other?

How can I decode one by one?

You could try something like this:

final fileNames = ['file1.mp3', 'file2.mp3', 'file3.mp3'];
for (var fn in fileNames) {
  await JustWaveform.extract(audioInFile: File(fn), audioOutFile: File('$fn.wave')).last;
}

That's the basic idea, anyway, modify it as needed to get the audio files from different input locations and store the waveform files in different output locations.
