Choppy mic audio

[Key19]

Howdy!

I just recorded about 30 mins of footage using two mics connected to an M-Audio M-Track Duo. Both mic tracks sound very choppy, kind of like if you had a Noise Gate applied and it was too strong (or that the mics were recording at a different sample rate than OBS was, but I also double checked that and they were both 48k). The starts and ends of words abruptly cut in and out as mic input rises and falls with comments.

I had just recorded a single mic recording prior to this and the single mic sounded fine (same primary mic, and then a secondary mic was added for the two-mic recording). So I'm not sure why the mic capture issue started when I introduced the second mic.

Here is my log from the choppy audio recording session: https://obsproject.com/logs/22CAK5XOW5AwRf6Z

Here is a brief sample of the bad audio: https://youtu.be/0tJOlwmGBK4

I double checked to make sure there weren't any filters applied to the mic sources and there were not. So I'm not sure why it sounds the way it does. But the audio quality is unusable as it stands right now. I would like to resolve this so that I can do a re-take recording of the session.

Thank you for your help!

I made a new recording just now and the issue seems to be resolved. Originally (with the bad recording), I had added my two mics as two separate Audio Input Capture sources and used those. I deleted both of those, then I went into Settings -> Audio and disabled both the Mic/Auxiliary Audio and Mic/Auxiliary Audio 2 Global Audio Devices. I applied this change and hit OK. Then I went back into Settings again and added Line 1/2 (M-Audio M-Track Solo and Duo) into both the Mic/Auxiliary Audio and Mic/Auxiliary Audio 2 Global Audio Devices. This created two fresh mic inputs in my Audio Mixer. I panned my primary mic to the left and panned my secondary mic to the right and then selected the Mono checkbox for both. I then tested and the mics sound great (like normal when I was only using one mic).

The only thing that I can theorize is that if you use Audio Input Capture to create Sources for two mics that are using the same audio interface device, it glitches the sound quality for some reason. Assigning the mics as Global Audio Devices seems to eliminate the issue.

Hopefully this helps anyone else with the same issue.
