Introduction

You can record your live stream with multiple audio tracks in OBS. When you live stream via Muvi Live and OBS, you can select the multi-track audio recording option in OBS and record the live stream in multiple audio tracks. For example, you can use one audio track for your microphone and another track for your desktop presentation.

Note: When you live stream you can only select one audio track. However, for recording, multiple tracks can be selected.
