EXAMPLE PIANO TEACHING SET-UPS
1. Two cameras and easy audio
Video
-
A laptop webcam pointed at the teacher's face; and
-
An overhead camera showing the teacher's hands on the keyboard. The overhead camera is an iPhone 7 running the Epocam HD app which converts the iPhone into a webcam.
Audio
A USB headset records the teacher's voice and the sound of the instrument in the room. Not perfect, but means you do not need a mixer/audio interface.
2. High quality stereo audio
The following setup produces a high quality STEREO sound. Note that "stereo sound" must be enabled in Zoom.

Audio
-
Left and right feed from keyboard goes to a Digital Audio Interface, in this case a Focusrite Scarlett 4i4.
-
Teacher's voice captured by a lapel mic which also goes through the audio interface.
-
Audio is routed to a "virtual" audio interface called "Zoom mix", using Loopback software by Rogue Amoeba. This enables you to route any audio source on your computer to Zoom.
-
In Zoom, the microphone is set up to be "Zoom mix". In the screenshot below, the teacher's mic is in input 1, the stereo keyboard is in channels 3 and 4.
