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

Check out this demo on the asset library: https://godotengine.org/asset-library/asset/526

How does it work?

It uses the push_frame() method on an AudioStreamGeneratorPlayback object, which is inside of an AudioStreamPlayer node, to generate audio frame-by-frame based on pulse_hz.
