AudioLink
Download Page for audiolink-2.1.0-cluster.1.unitypackage
To use AudioLink, download the audiolink-2.1.0-cluster.1.unitypackage from the download page above and import it into your project.
Add the AudioLink.prefab from the Runtime folder to your scene and set up the AudioSource you want to reference in the world. If you want to change AudioLink parameters from a script, add a Scriptable Item to AudioLink.prefab and use AudioLinkHandle.
Because AudioLink reacts only to the in-world AudioSource referenced by its component, it does not respond to voice chat, emote sounds, system sound effects, and similar audio. In addition, as of April 2025, avatars, craft items, and accessories cannot use shaders that support AudioLink, so the effect is limited to objects in the world that use AudioLink-compatible shaders.
Cluster runs on multiple devices (Windows, Mac, Android, iOS) and with different UIs (VR and non-VR). If you use a shader that is not compatible with the graphics API of some devices, the appearance may differ from what you expect.
AudioLink signal processing is performed on each device. Therefore, depending on the time a user joins and the performance of their device, an object’s appearance may differ from that on other devices.
For more details about AudioLink, see the official README.

You can change how sounds sound in the world. It does not affect sounds generated by the Cluster app, such as voice. Also, settings such as Mixer Effects, which include Steam Audio Reverb, and SteamAudioSettings will not be reflected in the Cluster app.
