Add visualisation / simulation of multichannel audio in dome

[Tunkali]

In some cases it would be helpful to test multichannel audio with physical positions in dome. There could be different setups like the seating options (eg. stereo, quad, surround 5.1, 7.1. dolby atmos, spatial soundwave with 32 speakers).

I would also be very interested in the possibility of multichannel audio output, especially the playback of first-order Ambisonics audio.

Unfortunately, I only work with Unreal Engine; otherwise, I would have tried to implement it myself. Many thanks for your work, and greetings from Berlin.
