Instead, take some time to figure out how to get your computer to merge two separate audio inputs-your microphone, and your computer audio-into a single output, which would go into your video stream. Or maybe you were hoping that the computer would just let you switch back and forth easily-ha, if only! Maybe you are planning to play a recording over external speakers, which the microphone will then pick up and put back into your video-but this will distort the audio significantly. As you think of putting your classes online amid the COVID-19 safety measures, you may be imagining that you’ll make videos or other media in which you talk into your computer microphone as well as play music into that same microphone.
