# wave_generator
A dart package to generate audio wave data on the fly.
## Usage
To use this plugin, add `wave_generator` as a [dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).
### Example
``` dart
import 'package:wave_generator/wave_generator.dart';
() async {
var generator = WaveGenerator(
/* sample rate */ 44100,
BitDepth.Depth8bit);
var note = Note(
/* frequency */ 220,
/* msDuration */ 3000,
/* waveform */ Waveform.Triangle,
/* volume */ 0.5);
var file = new File('output.wav');
List bytes = List();
await for (int byte in generator.generate(note)) {
bytes.add(byte);
}
file.writeAsBytes(bytes, mode: FileMode.append);
});
```
Or string together a sequence of Notes
``` dart
await for (int byte in generator.generateSequence([note1, note2, note3 /* etc */])) {
// ...
}
```
### Features
* Sin, Square, Triangle waves
* 8 Bit depth
