Hello !
Thanks a lot everyone. Thanks for the book info Vadim.
I was not notified that this thread was going on, so I forgot it.
I managed to make something work, but sonically speaking, it was far from a
moog filter :-)
The appearance/disappearnce of the resonance effect was pretty brutal, and

So... how do you do a resonance in a lowpass circuit? :-) not the
math, not the code, just the architecture.
There are many different ways to create resonance in a lowpass circuit

In the physical world, resonance can generally be observed as the
frequency-dependent cyclic exchanging of energy between potential (stored) and
kinetic (active) forms. A pendulum is a basic example: at either end of its
swing a pendulum exhibits purely its maximal stored potential energy while

A HHR performes both simple reflection and self oscillation. At the
beginning of the triggering phase the sound runs into it and is
reflected at the inner walls. A little part of the sound comes out
through the hole while a larger part is reflected creating steady waves
as known in all rooms

Resonance is just delay with feedback. Resonance occurs when you delay a
signal and then feed it back with some gain to the input of the delay "in
phase" with the original input, which means the delayed signal adds
together and boosts the input level to the delay. If you use a normal
digital delay
Resonance is the characteristic of some systems to store and release energy
at particular frequencies. It's not limited to filters, mechanical systems
like springs or pendulums have resonance (get on a swing at the park and
try to change your frequency and you'll feel the effects of resonance).
The resonance in low pass filter with an order greater than 2 is basically just
a feedback from the output to the input. You need to switch the polarity of the
signal, in other words, you subtract the output from the input, in order to
place the feedback point to the point, where the phase
Hi all,
I follow the llist for a while, but I am not a DSP programmer, I do DSP
audio apps for about 20 years now, for sonic core plateform "Scope" and
Xite". I begin with other things like juce or flowstone, but so far,
scope is still far superior in terms of sound results. Too bad there is no
