Oh interest challenge of the definition of resonance. The typical textbook
diagram shows a little local bump at some frequency in a bode diagram, but
if you consider dc the resonant frequency, then the only way to show a bump
is by being higher than all the other frequencies (i.e. monotonically
This code is also dangerous "LGPL" :-)
Seriously, I'm afraid this is also too much for him. Code is not really
good to explain solutions. I prefer the clarification and let people
code themselves.
Let's try it this way:
1. Apply an anti aliasing filter with an edge frequency of about
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
How about freezing and stretching moments. Is this resonance?

I've been wondering about the connection that resonance and filter orders at
least 2. That's 2 delays (and feedback).
But if you're limiting the resonant frequencies to DC and Nyquist, then with a
one-sample delay digital filter, you can have something like "resonance".
Even if the
This solution, without using any low pass filters before and after the
desimation, will generate a lot of aliasing frequencies, Kjetil!
Here is another solution:

Yes. The term helmholz resonator should be a hint ;) Basically when a

frequency that corresponds to that delay amount. For very long echos we
don't hear it as a resonance, but for shorter delays it will boost higher

where is low pass filter?

Maybe this will give you an idea:
48khz -> 8khz:
float get_output_sample(get_input_sample){
static int i=0;
static float sample;
if (i % 6 == 0)
sample = get_input_sample();
i++;
return sample;
}
8khz -> 48khz:
float get_output_sample(get_input_sample){

Hi DSPers,
I would like to reflect a bit about creating (primarily music) synthesis
machines,
or possibly software, as sort of talking about a dream that has been of some
people
since let's say the first (mainly analog!) Moogs in the 60s. What is that idea

This is even more incomprehensible.
I'm looking for a simple example of code and explanation how to convert
signal of 48Khz freq samples to 8Kh ,do processing of signal and convert
8Khz to 48Khz freq samples.
Thanks,
Alex

Hello all
Is "feedback with delay" really resonance? I recognize many people describe the effects of "room resonanes this way", but to my understanding these are no resonances in the basic meaning but reflections. A resonance is a self standing oscillating system like a guitar string or an
