VRChat.World Usage

overview

AVPro is the primary supported audio implementation in VRChat. STIR utilizes AVPro's ability to ingest and decode 6-channel audio separately per audio source, where we export each filter to a single track and use AVPro to control which sources get which audio.

Unity Audio is not supported.

usage

• locate (or add) a VRC AVPro Video Speaker component attached to an Audio Source.
• use the Mode dropdown to assign a channel to the selected speaker.

AVPro's channel layout is as follows:

channel	AVPro mode
1	Mono Left
2	Mono Right
3	Three
4	Four
5	Five
6	Six

important notes

• the Stereo Mix AVPro mode is a mix of channels 1 and 2 and cannot be edited manually.
• if you are using a 5.1 or higher channel configuration, channel 4 will be affected during runtime by AVPro applying its own in-built lowpass filter; it has been tested but it sounds like bass played through a glass of water. your mileage may vary.
  • this does not occur on 4-channel (4.0) or lower configurations.
• 8-channel audio is technically supported as AVPro does expose two extra channels; this may become a feature in the future but currently is limited by decoder support.
