We give music lessons via Zoom calls and achieve good quality sound by using a mixer as the "microphone" in Zoom.
One of our students wants to have the same setup, however, I've hit a snag in my mind for what to tell him. The three components are microphone, guitar, and backing track. All three go into the mixer, and then we USB out from the mixer to the computer and use that as the microphone in the Zoom settings. Simple.
The problem comes in with the backing track. We use a software program called Band in a Box, and we play the backing track from a separate laptop. So the audio out from that laptop goes to our mixer. The audio out from the computer where the zoom call is running, goes to speakers for the teacher to hear the student on the other end of the call.
So the problem in my mind currently, is how does the student achieve the same end result with only one computer? In other words, the audio out from his computer would need to carry both the audio from band in a box, and the audio from the other end of the Zoom call. This particular student is located in Europe; I can figure out what mixer to recommend to him, but is there any type of device that would address the audio out problem? Maybe I'm missing something obvious... Thanks for any suggestions.
