Hey all & perhaps the wizard @IvanC
I’ve been using the IIR filters and have them modified a bit and in separate files from the library. I’m now taking a look at the changes going between LP -> HP -> BP as a user.
With the LP & HP, when the Q is boosted the peak raises on the filter, whereas with the BP filter the peak stays uniform in volume and the filter (width) grows or shrinks. this means you get some level jumps as you move between them.
I’ve seen in other places people have them setup so the peak after the Q is uniform through BP / HP / LP, is there a change to the coefficients to make this possible, or are people simple adding some gain compensation after the BP filter processing to match all the peaks up. I saw two different equations for the BP in the filter cookbook stuff, but not sure if that’s what this is addressing?
