2.0.4 recorded stereo mix and mic split audio

I recorded audio that was streaming online, i only wanted stereo mix but it recorded from 2 sources my mic and my laptop, when i play the recording back i can hear both stereo mix and the outside recording, how do i split these so i can just hear stereo mix, i dont want to hear what the mic was recording. if its too late to split the audio, how do i at least make it so it sounds better quality and so i cant really hear the streaming audio and not the stupid mic recorded one?
thank you :ugeek:

I believe that’s selected in the Windows Sound Control Panels. That’s not an Audacity setting.
