# just_waveform

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



## Usage

```dart

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.

  }

});

```
