Multiple Audio Track Recording Guide

Setting your audio sources to record to multiple tracks is useful when working with an editor after you are finished recording in OBS Studio. It is important to note that all standard video players will only play back one audio track at a time so if you are not planning on processing every video through an editor before publishing it, send all of your audio sources to track 1 like you see in the example below.

Instructions

In the Audio Mixer dock, click the gear icon at the bottom left to open up the Advanced Audio Properties window Note: you can also access this from Edit in the menu bar
Assign each of your audio sources to its own recording track. In this example, each source is assigned to track 1 to ensure they all pla yback when watching in a standard video player and tracks 2-6 are used to separate the rest of the audio
Go to the Settings → Output window and enable the tracks that you would like to record
