Recording source audio without interfering with the PC audio


New Member
Hi guys. I'm new here, as you can notice by my ignorance.

I would like to record a source, a video on a website, and record the sound of the said source without capturing at the same time my PC's audio. What is happening is that I get two sources of audio mixed together and that's obviously not good. What I have to do today is simply avoiding using my PC to let's say, watch a YT video at the same time that I'm recording a source on OBS, which is extremely annoying. Is that a way around that?

Thank you in advance.
