Which means you'll need a lot of IRs. So it's more efficient to
separate the filtering and the delay. Once that's done, you can
probably find a parametric description of the filtering in function
of the angle of the driver. It doesn't need to be exact - a lot of
what a Leslie produces is there not by design but by accident.
