ParametricEQ.pd

This might be a very specific issue, but I've been trying to figure out the core of my issue, and I keep failing. I'm trying to create a band-pass filter using the 'biquad~' object given the logic below:

Given 'G', 'w0' and 'deltaw' are adjustable.

However, it seems like no signal is passing through the filter at all. I should disclaim I'm still rather new to PD, so there might be some obvious mistakes I fail to see.

Any suggestions would be greatly appreciated!

@buddybudbud It needs some audio input...... so this should get you going I hope..... biqu.pd
You had the wrong output of [readanysf~] connected.
You had disconnected audio from the output of [biquad~] by connecting [env~] which outputs a number (dB) and no audio.

Of course! Worked like a charm, highly appreciated!

Look up the order of coefficients used by biquad. I think it may be a1 a2 b1 b2 b3 ?

Edit: never mind, just saw you sorted it anyway

Thanks for your reply! Seems like the coefficients are put up correctly, I am however experiencing another issue regarding this you might be able to assist with: https://forum.pdpatchrepo.info/topic/10730/creating-a-bandpass-filter-using-biquad
