I have tried to use table to create a sine and cosine as I tried cycle~ and it is using up too much CPU and causing my software to glitch. I have yet to get the table object to work. I have about 48 different number streams coming in from my hardware device and the CPU for my total patch is 95%! Is there an good place to find an equal-power pan that doesn't require cycle~? Or does anyone have any ideas about how to efficiently perform equal-power panning? Any help would be most appreciated. I have included the subpatch that I am working on.

hello,

in this patch you'll find three different ways of panning. two equal power and one equal amplitude. it outputs values between 0 and 1 that you can use to control the amplitude of the left and right signals. you might want to smooth things a little bit using a line~ or you can just use sig~ to convert the floats to signals.

if efficiency is an issue, a lookup might be preferable over running the math on the fly. in that case you could use for example table or coll. look at the help files for these objects.

i normally use the external cppan~ by Nathan Wolek. it just works and it's efficient because it uses a lookup table.

hope this helps.
