Not a ready made multi band equalizer, but the 'else' library also has a biquad coefficient generator, which offers more options than the ggee library (see else/bicoeff). Else also has ready made filters that don't require biquad~ and take audio signals to control all the parameters (ie. [else/eq~], [else/lowshelf~], [else/highshelf~], etc).

I thought about making a ready made parametric in else, but you can easily build it your own. For the lowest and highest band you need to use lowshelf and highshelf respectively. Then use "eq~" for the mid bands.

have a look at the "ggee" library!
there are a couple of objects which mimik the usual EQ filters and output coefficients for [biquad~].
besides [lowpass], [lowshelf], [highpass], [highshelf], [bandpass] and [notch] there's also a [equalizer] object which is a typical peeking filter with settable center frequency, bandwith and gain.

Betreff: [PD] parametric equalizer

Hello dear pd lovers,
I wonder if someone as implemented a parametric equalizer similar to the ones you find on mixer : like three band LOW MID HIGH, with -/+ X dB so that when everything is +0 dB, the output is flat and similar to input.And eventually with Q/curve/spectral transistion parameters ?
I know this is a very large question and that there might be a lot of different implementations, but I wondered if there are "standard" solutions.Vanilla preferred or stable libraries...

Thanks !
