# Overview of Usage and API

> Create audio mixers from scripts via the AudioMixer API.

The Audio Mixer is a self-contained asset with a [streamlined API](/engine/6000.6/script-reference/unityengine/audio/audiomixer.md).

You can find music-related demos in the [audio demos](https://github.com/Unity-Technologies/AudioDemos) repository.

The [native audio plugin](https://github.com//Unity-Technologies/nativeaudioplugins) repository provides the official SDK for developing custom extensions, as well as examples involving complex routing, custom processing and custom generation of audio in the mixer.
