Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

Just Waveform is a Flutter/Dart package that extracts waveform data from audio files, enabling developers to visually render waveforms in their applications. Designed for music and audio apps, it processes audio files efficiently on Android, iOS, and macOS. The package provides raw amplitude data suitable for custom visualizations, offering flexibility without built-in UI components. It's ideal for creating audio players with real-time waveform displays or visualizers.

Audio player waveform visualization
Real-time audio waveform rendering
Music app development
Audio file analysis
Custom audio visualizers

Key features

Extracts raw waveform amplitude data
Supports Android, iOS, and macOS
Lightweight and efficient
No built-in UI components
Simple API for waveform extraction

Suitable for

Developers building audio players
Creators of music visualization tools
Apps requiring audio waveform analysis
Cross-platform audio applications
Projects needing lightweight audio processing

Considerations

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.
  }
});
