@raphlinus with you background (e.g. in low latency audio processing), do you happen to have any ideas on software (development) for realtime band/choir rehearsals? A lot of choirs that started using zoom (because of its original sound setting) are missing the singing together.
It's something I've thought about a little, but there are so many challenges up and down the stack - device audio, codecs, network latency. I hope people are working on good solutions!
