Virtual Audio Cable _best_
Standard software like Zoom, Skype, or Teams only allows you to record one audio track. If you try to record a remote guest, your voice and theirs are often mixed onto one track. If their dog barks, you can't edit it out without ruining your voice.
Standard screen recorders often struggle to record internal system sound. VAC allows you to set a virtual cable as the default recording device, letting Audacity, OBS, or Adobe Audition capture pure, high-quality digital audio from your browser or media player without any background noise. virtual audio cable
