just_waveform

This plugin extracts waveform data from an audio file that can be used to render waveform visualisations.

Usage

final progressStream = JustWaveform.extract(
  audioInFile: '/path/to/audio.mp3',
  waveOutFile: '/path/to/waveform.wave',
  zoom: const WaveformZoom.pixelsPerSecond(100),
);
progressStream.listen((waveformProgress) {
  print('Progress: %${(100 * waveformProgress.progress).toInt()}');
  if (waveformProgress.waveform != null) {
    // Use the waveform.
  }
});
