Audio sounds horrendously choppy and distorted

Your logfile says you're running PipeWire. That's fairly new, so there might still be problems there.

Generally, it sounds like a mismatched sample rate, stretching a faster incoming stream to fit a slower outgoing rate, without actually resampling. So it sounds like a tape or vinyl slowdown. Pretty soon, it realizes that it's horribly out of sync, resets, and does the same thing all over again.

Your log says you're running OBS at 48kHz, which is the faster of the two common ones. The slower common rate is 44.1kHz. If ALL of your sample rates throughout the entire system (not just OBS, but everything) were matched, it probably won't do this.

You haven't given enough information to tell you how to check everything *else* on your rig, but make sure that ALL of it is running at 48k.

Well, changing the sample rate fixed the choppy-ness, but now the audio is a distorted mess.

It's still slow. Pitch down. Are you *sure* you found ALL of the sample rate settings? You might have just moved the problem to a different place that has a more frequent reset.

Also:
11:27:10.356: [Loaded global audio device]: 'Mic/Aux'
11:27:10.356: - filter: 'Noise Suppression' (noise_suppress_filter_v2)
11:27:10.356: - filter: 'Gain' (gain_filter)
11:27:10.356: - filter: 'VST 2.x Plug-in' (vst_filter)
What does the VST filter do?

I fixed the issue by reinstalling obs, then under pulseaudio using the gain filter to limit the aduio volume, then i limited the microphpne volume from the system settings thyemselves. I think the distorded sounds was because on a system level the mircophpone input is VERY loud and distorded as a result.

Clipping sounds different from that...unless you normally talk that slow and deep. There was definitely a speed issue in there somewhere, but if re-installing fixed it, good for you!
