flutter_ogg_piano

Put sound and adjust pitching with Android internal codes in Flutter

Getting Started

Implementation

To implement this plugin in Flutter, add this line in dependencies section in pubspec.yaml

flutter_ogg_piano : ^1.0.2

Example

Before you using this FlutterOggPiano class, you always have to call init method first. There is maximum number of sounds which can be played for Android, default is 128 and you can change this value Be aware that this plugin can't hold sound longer than 5 seconds duration.

FlutterOggPiano fop = FlutterOggPiano();

//In somewhere of codes...
fop.init();
//With maximum number of sounds
fop.init(max: 64);

This example shows how you use FlutterOggPiano with sounds file saved in assets folder. In pubspec.yaml file...

assets:
  - assets/123.ogg
  - assets/456.ogg

You can load sound file like this,

//In somewhere of codes
rootBundle.load("assets/123.ogg").then((ogg) {
  //If you want to overload already existing sounds...
  fop.load(src: ogg, index: 1, forceLoad: true);
  //If you want to load it normally...
  fop.load(src: ogg, index: 1);
});

rootBundle.load("assets/456.ogg").then((ogg) {
  fop.load(src: ogg, index: 0);
});

//Keep going for more sounds

When you make it play sound, you have to put note value. 1 value difference is 1 semitone difference. Negative value for lower pitch and positive value for higher pitch. Zero for same pitch with source sound.

//Somewhere of codes...
fop.play(index: 1, note: -1) // 1 lower semitone with 123.ogg sound
fop.play(index: 0, note: 3) //3 higher semitones with 456.ogg sound

Don't forget to release it after using this class

fop.release();

It will automatically prevent playing/loading sound with released state, but you can simply check if it's released by calling this

fop.isReleased().then((r) {
  //Do something
})
