is there something in pd that does basic equalizing?

i just read about fir~ ...is that the only option???

I suppose you can use lop~ and hip~.

I used them for 3 band equalizer and they worked rather well (for my ears), but I think their sounding wasn’t perfect.

Is fir~ - the finite impulse response filter? That kind of filters is best for equalizing.

iemlib has various types of filters that might make it easier to do EQ - i think i used them once for simple bass/treble controls (using low and high shelving filters).

what about Yves Degoyons external [filterbank~] it's a set of several band pass filter. Could be download at:
