Question / Help Multiple audio tracks

[NoriMori]

"Added the ability to save multiple audio tracks with different mixer configurations on a single recording in advanced output settings"

I honestly don't understand how this feature works or what it's supposed to do. I checked multiple tracks in the advanced output settings, and there were no discernible effects or results. What is the outcome of using this supposed to be?

Also, what is the use of the "Audio Input Capture" source? What is this supposed to do?

I guess I'll have to make a tutorial for this.

1) Assign your audio sources to respective tracks in Advanced Audio settings.
2) Go to Settings > Output
3) Set Output Mode to Advanced
4) Go to the Recording tab
5) Change the output file type to something besides FLV
6) Select which tracks should be included in the recording
