# Audio Generator
|
||
|
|
|
||
|
|
This is a demo showing how one can generate and
|
||
|
|
play audio samples from GDScript.
|
||
|
|
It plays a simple 440 Hz sine wave at 22050 Hz.
|
||
|
|
|
||
|
|
Language: GDScript
|
||
|
|
|
||
|
|
Renderer: GLES 2
|
||
|
|
|
||
|
|

## How does it work?
|
||
|
|
|
||
|
|
It uses the `push_frame()` method on an [`AudioStreamGeneratorPlayback`](https://docs.godotengine.org/en/latest/classes/class_audiostreamgeneratorplayback.html)
|
||
|
|
object, which is inside of an
|
||
|
|
[`AudioStreamPlayer`](https://docs.godotengine.org/en/latest/classes/class_audiostreamplayer.html)
|
||
|
|
node, to generate audio frame-by-frame based on `pulse_hz`.
