I’d like to see Meta create an external app for Mac/windows that broadcasts multichannel audio that can be accessed by gizmos inside a world. Each gizmo could select an individual channel or a stereo pair. The streams should have some password protection so they can only be used in worlds where the owner of the stream has granted permission. Stream gizmos could play audio as global world audio, or as point source audio with different projection patterns and range where they would function like an array of speakers.
This would be incredible for live music and DJ performances without the clunky work arounds and limitations of using a bot account on a PC which uses unnecessary CPU and bandwidth.
