From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How can we combine two audio recording inputs (mics) into one audio input source in Manjaro? (sh.itjust.works)

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.

Hardware isn’t the same as software so I feel like my point largely stands lol. There’s no way their room is treated either.

I’ve regularly run 2-5 person talking head recordings for years. Mic placement is everything. If they’re too close together there’s no solution. They need to be 180 to each other with hyper cardioids

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.

Then it’s not echo you’re getting, it’s bleed. Y’all should look into kill switches for each mic. There are really great set ups that allow you to kill the mic whenever you are releasing a button or pedal, so as long as you get used to the habit of only pressing down when you’re speaking (very doable) that is also an option. Discord also support push to talk if you want the free/more hassle version.
