My partner and I are running Manjaro and very new to it. Trying to switch as much as possible over to daily use with Manjaro. We have pipewire, not pulseaudio
We record multiple times a week on OBS, and my partner and I are in the same room. We have two mics side by side both inputs going into my PC. Linux, and therefore OBS, are recognizing the two mic inputs separately as you might expect.
OBS can set up both of these separate inputs, but the issue is we’re having significant problems with echo and the noise suppression/noise gates are not sufficient.
This was not an issue on windows, where we used Voicemeeter to combine our inputs into one mic for OBS. I am looking to emulate that on Linux to see if it solves our problems.
We have tried a mic merge sink, but it creates an OUTPUT device, not an input device.
SOLUTION: QPWGraph was the answer (or something like it, Helvum was also recommended) While it looks intimidating at first you just need to understand it’s a series of outputs and inputs and you play mix and match. This allowed us to take the outputs of the mics and connect them directly to a single OBS mic source. This 100% did all that Voicemeeter was doing for us, and the results were also the same.
We do not experience echo, overlap, feedback, or any of the issues we were having by adding the two mics separately in OBS. Our issue was NOT the setup, as some people focused on here. As soon as we got the mics going into that same input, all was good and we successfully ran a recording session 100% in Manjaro.
In the end, this did everything we wanted from Voicemeeter + MORE, as I can now isolate different outputs as well. So for instance in recordings I can manage the volume of discord and the background music separately. So this was an amazing solution and the result was exactly what was needed, and ultimately was much easier than Voicemeeter.
Thank you to those here that recommended it, and the people at the Manjaro forums.
I can think of some commercial audio processors that can help with that, but they are super pricey.
I can’t think of a linux application that has this capability. If there is something out there that offers AEC (acoustic echo cancellation) on linux with two mic inputs, id also be interested.
One way to help with this as far as inexpensive hardware is to make sure you’re using cardioid dynamic microphones, and not omnidirectional condenser microphones. Cardioid dynamic mics generally pick up audio directionally, like from the “front”. You have to be right up on the mic in order to have it record any type of audio. They generally wont pick up environmental sound from anything more than a few feet away. You can just point them away from noise you don’t want to pick up.
Yes, I’m sure there are multiple professional software solutions that are expensive but can do it. Reconfiguring the equipment is much cheaper.
Even basic stuff like teleconferencing software can do it, like do y that when Zoom is playing audio it doesn’t pick it back up through a desk mic, unless the feedback is really bad.

The room is not professionally treated for sound, but we do have one wall (behind the mics) 90% covered with 2" sound dampening foam. Lots of stuff on the other walls, rugs, etc. It is not a bare-bones room. Our mics are good quality cardioid mics and while our setups are not 180° back-to-back, the mics point away from each other when in use. I don’t know if I can explain well enough with words, but we sit side-by-side with the mics between us on arms. They swing down between us, stretch out towards us, and point away from each other. They are about 1.5 to 2 feet apart from each other, pointed away, when in use.
