Here are some ideas, software related at least if I recall.

Audio stereo streaming of GP (+video/webcam)

In order to provide a solution for the piano lesson of my childrens during the COVID-19 shutdown, I am looking for the best way to stream a GP stereo output possibly with a webcam (Skype, WhatsApp, realtime Youtube streaming, etc…) to the iphone or ipad of the piano teacher which as no particular computer skills. I started to test with Skype and could stream the GP audio output to my iPhone but if was not stereo and the sound was quite poor… Any other idea ?
