it is always useful to have music signal related abstrations in full-signal available.

try to implement something simple and common such as a tremolo or vibrato to the paf~ external using data rate and you´ll see what i mean..

F12.paf.control.pd says that there is a paf~ external, but I can't find it. This page by Miller Puckette describes paf:

just use his patch, no need to look for an external,

the max external for example does not support signal input, therefore a custom patch is there also preferred.

neither poles and zeros nor fft filters are minimal phase, but FIR can be if you design them symetric.

short answer: because mpeg conversion also includes FFT at one point.

all of these things can be done with various combination of addition and multiplication.

there is no need to measure the RMS of a known waveform, since you can calculate it offline much more precise. the energy of a wave/halfwave/periodic vibration is the size of the geometric surface: 1 for square, 0.5 for tri and saw, 0.707 for sinus...

i just read the starting post again - and as it seems i did not do that before asking that question.

it would have been my next question why you do not use coefficients which somebody else made already.

no i havent tested those yet, but i might come back one day with proposals.

in my opinion the usual 16x oversampling is almost unavoidable for FM or PD synthesis.

the attempt to take care of the bandlimiting with prior components has to fail everywhere, where even sinewaves as sources will already hit the nyquist barrier.

oh, you can also make it shorter by writing 10^5

i wonder how you came up with the filter topology and settings and how you were deciding/balancing the filter curve precision vs the LR runtime difference/phase shift.

HRTF FIRs are a beast, and in my experience it already sounds terrible when you take it over to an fft filter.
