rundown

this utilizes AVPro's ability to ingest and decode 6-channel audio separately per audio source, we export each filter to a single track and use AVPro to control which sources get which audio

Unity Audio has not been tested and is likely not to work, AVPro is generally a better choice in every circumstance

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

channel layout

[!NOTE] this channel layout will be customizable in the future, this information is highly volatile

layout

currently, the channel layout is as follows:

channel	response	AVPro mode
0	left [mono]	Mono Left
1	right [mono]	Mono Right
2	mids (bandpass)	Three
3	none	Four
4	lowpass	Five
5	highpass	Six

details

• channels 0 and 1 receive the original, unedited left and right channels of the input source
• channel 2 takes the left channel, applies a combination of lowpass and highpass to isolate a frequency range
• channel 3 is unused (refer to the footnote)
• channel 4 takes the left channel, applies a lowpass filter and an optional tremolo LFO
• channel 5 takes the left channel and applies a highpass filter

while all of these channels ingest the left channel, it is important to remember each channel is mono and will not be panned left or right by STIR or OBS

footnote

• the Stereo Mix AVPro mode is a mix of channels 0 and 1 and cannot be edited manually
• channel 3 does not receive audio due to AVPro applying its own in-built lowpass filter upon runtime; it has been tested but it sounds like bass played through a glass of water
• 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 encoder support
