I’m experimenting with spat5.pan~ knn and vbip on a 26 speaker dome, and would like diffusion to switch from a point source to either the whole dome or the lower ring. What would be the most convenient way to achieve that?
I tried using spread, but am not getting the desired results. I would interpret the /spread/mode omni and azim to be made for that with
- whole dome: source position 0 0 0, spread mode omni, spread 100
- lower ring: source position 0 0 0, spread mode azim, spread 100
instead, the output is silent, until I wiggle the source position a little bit. Then 2. looks ok but 1. has some silent channels. I must be missing some basic understanding or some parameter like spread “radius”.
Thanks for your hints!
