ignoring the subtleties of things like ambisonics and filtered
channels for the time being, am i right in thinking that surround
panning is just simple math? my mental model is:
total_distance = 0
foreach speaker
speaker.distance = speaker.compute_distance (pan center);
total_distance + speaker.distance
foreach speaker
speaker.pan_gain_coefficient = speaker.distance/total_distance;
i think there is more to it than this. i know that this doesn't work
for stereo, for example - it doesn't produce an equal power pan.
can someone point me at some good references?
