Output multiple audio tracks in OBS

Multiple-Audio-Tracks-OBS.md

1. First open OBS settings and select Output, then set the output mode to Advanced, then select the Audio tab. You can name your tracks here.

2. Next, switch your output mode to Simple, and in the Recording section, check all of the audio tracks you'd like to use

3. In the main view, select the 3 dot menu in your list of audio sources, then select Advanced Audio Properties. From here, you can select the checkboxes corresponding to the audio tracks you named earlier. For instance, if you named track 2 "Mic", you can check boxes 1 and 2 on your Mic input and leave the rest unchecked. That way, when you're done recording, your microphone output will live inside audio tracks 1 and 2 on your recording. It's best to have all tracks under 1 checked since that's the default track that goes to your streaming platform (e.g., Twitch, YouTube).

4. When you're done recording, you can open your video in VLC, right click on the player, and select the audio track you want to listen to.
