By default, OBS likes to cram all your audio into one big stereo file. That’s fine, until it’s not. But what if your game audio sounds like a jet engine compared to your voice, or everyone on Discord decides to whisper like a ninja? Don’t spend hours attempting to adjust volumes in post (spoiler: you’ll lose). Do record your audio tracks separately. Trust me, editing those levels later will be a walk in the park.

Yeah, let’s set things up so that never happens again.


ADVANCED AUDIO PROPERTIES

Right-click in the Audio Mixer and select “Advanced Audio Properties.”


TRACK SELECTION

Choose the tracks you want to record. In this example, I’m recording game audio on track 3 and microphone on track 2.

Note: Track 1 (the default mixdown track) remains selected for live streaming.


ADVANCED OUTPUT

Now head to Settings > Output > Output Mode and change it from “Simple” to “Advanced.”


RECORDING TRACKS

With Advanced Mode enabled, you’ll see a “Recording” tab. Select the tracks you want to record in the “Audio Track” section and click apply.


ADJUSTING LEVELS IN POST

If everything went according to plan, your recorded video will boast two independent audio tracks for easy post-production adjustments. But wait, there’s more! OBS allows for recording up to 5 stereo channels or 10 mono tracks, giving you plenty of room to get up to something nefarious.


VERDICT

Recording multitrack audio in OBS is inevitable, so why not set it up now? Don’t worry, when (not if) you lose a few hours of recording due to a bad audio mix, this guide will still be here to help you out.
