onepole~ newbie doubt (what is 0.052456 ?)
Nov 02 2016 | 1:11 am
Hi everyone, I'm a newbie and I'm studying [onepole~] object. In the help patch - in the highpass example - there's a curiously precise detail: the cutoff frequency is obtained with a slider that is the exponent of the base 2. Actually the exponent is the slider multiplied by a very precise number: 0.052456. It can't be a random number. So, my question is: why precisely that number? What does it mean?
My second question is about the basic example: the two [filtergraph~] objects describe amplitude response and phase response. What does it mean? That applying a lowpass filter it changes also the phase around the cutoff frequency? And if so, why?
Thanks a lot for your help!
