hello
I'm using the [vcf~] filter quite a lot these times
of course, when you raise the Q factor, as the peak narrows, the volume
decreases
I would like to set up something automatic that tunes automatically the output
volume of vcf~ in function of Q
For example, something simple like output_lev = input_lev * k * Q (if Q > 0)
where k is a multiplicative factor
I don't know about this "k" factor ; I could find it empirically, but isn't
there a more serious way of determinating it ? (assuming the input signal is
white noise)
Also, when Q = 7, for example, what is the bandwidth of the filter ?
thanks a lot for your help
