- Audio picked up by Open Broadcast Software
- Two microphones picked up by Open Broadcast Software
- Game Audio through both commentators' headsets
- The microphone of whichever headset you're not wearing through the one you are wearing, allowing for both commentators to clearly hear when and what each other are saying.
Step One: Acquire Virtual Audio Cable
You can do so right here. It costs $25US if you don't want the ability to complain to the dev if something goes wrong. Less if you sail the high seas. This is the only investment we'll be making.
After installing VAC, right-click on your volume icon and take a look at your Playback and Recording devices.
|That's it there at the bottom. It's in the Recording tab as well.|
|Run it as an Administrator, just to be safe.|
Step Two: Preparing your Virtual Cables
Obviously we need two headsets. The two I am using are a mix of Triton and Logitech. We need to put these through one of our new virtual cables. I use Line 1.
To do so, go to your list of Recording devices, find one of the microphones you're using and right-click > Properties.
From here, we want the Listen tab. Check the (most likely unchecked) box labelled Listen to this Device and select Line 1 as the device to play the microphone back through.
Repeat the process with the second microphone.
In order to have full control on where the main game and application sound goes, we'll be shoving that all through Line 2. We can't use Listen functions, so we shall instead go to the Playback tab, right-click on Line 2 and set it as our Default Playback (and Communications for safety's sake) Device.
Step 3: Configuring the Headsets
Return to your Virtual Audio Cable start menu. We need to use a program it provides to tell what all our headsets are going to be picking up from our fake cabling.
|Make sure you're using MME, not KS for this. Don't forget to run as Admin!|
This will bring us a new configuration tool. We need the Wave In option to be Line 2 (our main audio). We need Wave Out to be one of our headsets.
In order to hear only the other microphone, we need to fire up another instance of this Audio Repeater. This time we want the Wave in to be the name of that microphone while the Wave Out stays the same as above.
Then simply repeat this process with your other headset. You'll end up with four copies of the Audio Repeater like so.
And there you have it! Run some test recordings of your combined audio + microphones to make sure it's all working then enjoy speaking with each other! If you need to adjust the game volume, use your good ol' Windows Audio Mixer by right-clicking that sound icon.
I hope this all makes sense to you. If not, shoot me a comment and I'll edit this piece accordingly.
