A Flutter Sound Pool for Playing Short Media Files

soundpool

A Flutter Sound Pool for playing short media files.

Sound Pool caches audio tracks in memory. This can be useful in following scenarios:

  • lower latency between play signal and actual playing of the sound (audio does not need to be read from disc/web),
  • the same sound may be used multiple times.

Inspired by Android SoundPool API. This also means that multiple optional features are supported on Android only.

Example:

    import 'package:soundpool/soundpool.dart';

    Soundpool pool = Soundpool(streamType: StreamType.notification);

    int soundId = await rootBundle.load("sounds/dices.m4a").then((ByteData soundData) {
                  return pool.load(soundData);
                });
    int streamId = await pool.play(soundId);

DOs and DON’Ts

  • DO NOT create the Soundpool instance multiple times; DO create a Soundpool for logically connected sounds (ex. sounds for level, sounds with the same streamType),
  • DO NOT load the same file multiple times; DO load it once (ideally while the application is starting), store sound id and use play(soundId),
  • DO NOT leave sounds loaded in memory when no longer used; DO call release() or dispose() when sounds are no longer useful,
  • DO NOT play music files; DO use plugin that is intended for that.
