Can audio and video be recorded separately?

I am try to see if I could record audio and video at the same time but it is only recording video in my videos folder and then audio is posted somewhere else on my computer.

Have you found where the audio is going? If not, and it's not in the video file, then you're probably not recording it. That's a different question.

OBS doesn't create separate files. It puts everything in one file. Everything that you've enabled, that is.

Another possibility is that you actually do have the audio that you want, on Track 2 or something other than Track 1, and the player that you're testing with only does Track 1. Try VLC, if you haven't already.

Exactly
OBS Studio composite sources into a single output (by default/typically). So your composited 'video' file is the video and audio source(s), in one file.

*IF* your audio is NOT in the video file, then typically that means you changed a default audio setting
- Beware distinction in OBS Studio's Advanced Audio Properties for Monitor and Output.. .ie if you Monitor only, then you told OBS Studio to NOT record the audio. And then there is the sophistication Aaron refers to with Tracks. hopefully you didn't mess with/adjust Track recording options. if you did, the OBS Log per pinned post in this forum when asking for help, and possibly some screen shots, may be required to help you get back out of whatever you did. or reset OBS Studio settings and start over (depending on how complex your adjustments to the defaults were)

and...since OBS records both audio & video into 1 file, can you go in and separate audio from video in post, for editing either separately? thnx

Yep, I use Avidemux for that as you can copy & save any/all of the audio tracks that may be contained in the video.

Any video editor worth its salt can do that. If yours doesn't...we generally regard those as toys.
Likewise for reading the safe recording container - MKV - directly with no need for MP4 at all.

Here's a good free one that does both, and the one I use:

I believe using Shotcut requires a re-encode, just like all NLE's. Avidemux is just remuxing that audio into a WAV or AAC container.
Yes, but if you're editing anyway, then you're re-encoding anyway. Might as well only do that once, and use the same tool for the entire process.

If you just want to extract it, then yes, it's better to remux the same data into a different container.
