Hello all !<br>I&#39;d like to make a 2pole notch filter.<br>I found a few topics about notch filters on this list but I didn&#39;t understand everything.<br>I read that I could make one with biquad~ but this object is somehow obscure to me.
<br>I don&#39;t know how to deal with the 5 parameters. In maxmsp, you have the filtergraph~ object which &quot;translates&quot; your Freq, Q and so on for use with biquad~ but in pd I just don&#39;t get it... The filtergraph pd objects are also difficult for me to understand.
<br>Could someone explain me how I can make a notch with biquad~ (or with any other native pd objects) please ?<br>Thanks.<br><br>_y<br>
