Select specific window's audio to rec


New Member
Hi, I am an university student and I would like to record my lessons and in the meanwhile to watch the old one's, but I can't because OBS records the audio of the player over the audio of the lesson. How can I tell OBS to record the audio from only one window at a time (the window of the lesson)? Thanks in advance (Sorry for my english, but I am not a native speaker). Mattia
