So the problem has to be with OBS,
Uh, no, that is NOT what that means.
but I can't see anything in its settings that obviously need changing. Any helpful thoughts?
One issue you may come across is that the Windows Audio sub-system is basically pathetic
With a good mic, I'm guessing you are using ASIO and/or a DAW?
But typical DAW won't output to Windows Audio (again, 'cuz windows audio), but some do, and there are workarounds (some better than others)
The common refrain you will hear is to do your audio adjusting outside of OBS Studio, and then after all audio processing input into OBS Studio (vs using OBS Studio's audio filter/effects, etc).. ymmv
So,
1. don't ignore the pinned post regarding OBS Studio log when asking for help/support (link in my .sig). Personally, I advise checking it yourself, and first/foremost making sure all audio using same sampling rate
2. Share with the community your specific physical and software audio path
3. if top-notch audio quality is important to you, you may want to look into adding Core AAC audio encoder to your computer for OBS Studio to use
OBS Studio is a powerful, complex tool. Expect to take some time to learn its nuances. I am much more of a person who learns by reading vs watching a video, so from a non-gamer perspective, the StreamGeeks (PTZ Optics) free OBS Studio eBook may be a good starting point
Also,
- hopefully you have come across OBS Studio's Advanced Audio Properties and understand the difference between Monitor and Output.
- and then there is the basic of which audio device are you using to pick up your mic? In OBS Studio Settings, I disabled ALL global audio devices, and then added (and learning difference between referenced and duplicated sources) specific Audio source for my mic (from mixer) to appropriate Scene(s)
