Is it possible to use Voicemeeter with OBS Studio to add voice on game sounds? Usually when I record, I check two tracks in Recording, and in the mixer portion of OBS Studio, in Advanced Audio Properties I check mic for track 2 only. So the game audio gets recorded on track 1 and mic audio gets recorded on track 2, I get two separate audio tracks in VLC. Apart from Handbrake I don't have any encoding software, so I don't know how to add mic audio to game audio and balance their levels so that mic audio gets precedence when I'm speaking and after that game audio gets back to 100% volume when I'm not speaking.

Is it possible to use Voicemeeter to mix mic audio and game audio on different track, like track 3 and configure it in such a way that game audio automatically gets decreased in track 3 when there is noise from mic, and what is spoken through mic gets recorded a little more loudly on game audio on track 3?

I don't know what is Audio Monitoring in Advanced Audio Properties, is this setting something I can use to achieve what I want without using Voicemeeter?

Thanks

PS: What is the difference between Voicemeeter and Voicemeeter Banana? And which one should I use?
 
You can configure the Compressor in OBS to perform this action, it's known as Ducking or Sidechain compression. If you aren't going to be using editing software you might as well do it in OBS.

Add the Compressor filter to the Desktop audio source, set the Sidechain Source to your Mic.

If you set a super high ratio you can use the attack and release to tune the sidechain effect.

* Attack time is a ramp in, it is how quickly it goes from 1:1 to 32:1 compression. Think of it as a fade out time for your desktop audio, the longer the attack the more gradual the volume decrease will be
* Release is the opposite, how quickly the audio comes back to normal volume. You want a shorter attack and a longer release to make it sound more natural

Threshold is the level your mic input needs to be to trigger the sidechain, lower values will cause it to duck earlier

Start with something around the above, both the attack and release time are set longer to avoid the volume drastically changing levels, play with the threshold to have it sidechain earlier by lowering it

Hey, thanks a lot for this. It helps me so much. Will this get recorded on audio track 1 or track 2? I want to have two audio tracks, one with game audio only and another track with my voice and game audio. What threshold and attack would you recommend for me?

How do streamers or uploaders usually do this? What encoding software do they use?
 
The only problem with doing it this way is it will be recorded to track 1, so you will hear it ducking without the microphone from track 2. Sadly I don't know of any way to record an unfiltered version of the desktop onto another track

No problem. You were still of a lot of help. I'll add three tracks and add Desktop to track three and add compressor as you suggested in track 3 and see.
 
So this is what I did, in Audio Settings, I set Desktop Audio Device 2 to Default, so I got three tracks. So in the mixer, I did what you suggested for Desktop Audio 2 track but I didn't hear my voice. My voice was on the Mic track though, I'm a little confused about Threshold, I used -30.70 as shown in your screen, will reducing it to -60 make sidechanneling take effect more quickly or will increasing it -15. I tested at -50 and in track 3 game audio decreased but my voice was not there. Do I need to check Mic/Aux on Track 3 to make this happen. Thanks
 
On that video I used -35dB as my threshold but as you can hear my microphone input is quite strong to begin with. If your input isn't as loud then you would want to lower it even further to say -45dB or so, or make your mic input louder.
 
And yeah I didn't think about that, you can add a second version of your desktop using Desktop Device 2.

Streaming defaults to Track 1, so what I would do is set

Track 1 to be Desktop Device 1(With compressor filter) and Microphone combined.
Track 2 Microphone only
Track 3 Desktop Device 2 (No filter)

You don't need to worry about doubled up audio on stream because they can only hear Track 1. Set your recording to record 1, 2, and 3, which will give you exactly what you need
