Want to stream normally, but have a high-quality multitrack audio recording for later use? Well, you can leave your stream settings as normal and have a pure-audio recording output for OBS. Unfortunately, it’s not true “audio-only”, but it’s almost exactly that. With normal multitrack support, you can add audio with an even higher quality than 320kbps if you wanted!
