Mumble is fantastic for voice chat. Its text features are very basic, though, so people fleeing Discord would probably want something additional to handle that. Maybe Matrix.
A single location is a good selling point. Being able to jump into a voice chat, and still post things in a shared text chat is a good feature. Mumble should work a bit on that.
Since I don't know stream audio programming, C++ or gUI programming but am well versed on the shortcomings of mumble vs discord, perhaps I can bust out the llm.
