Hi,
Has anyone got an “N-Path” filter made in Nyquist?
I have an interest in making one, but it would be grand if someone has crossed those boundaries already.
Thanks,

Not that I know of.
Other than making one as a programming exercise, there really wouldn’t be much point as there are much better and easier ways to band-pass filter audio frequencies. (It could be quite fun to do as an exercise 
)
Yes Steve it is of “Fun Value”,
But what interests me about it is that it filters a Fundamental and all Harmonics up to a point.
And that point can be determined by the complexity of the “N” in the “N-path”.
Even some forms of simplicity of design can select to only “see” odd harmonics.
Doing that with a fixed bandwith for all harmonics…
It is of interest to me is the removal of an instrument from a song…
With the possible replacement of that instrument with another, or even a voice.
Take a song… Remove the Bass guitar and replace it with a Baritone Sax.
Or the replacement of a drum with something else interesting.
The thing that seemingly needs to be done to make this work is to make a Table to use as one uses in the (osc command.
Still gotta learn that trick.
So many fun things to learn.
Thanks,

Thanks,
That is very on-point.
I might need to soften the square edges of the windowing function with a hanning or hamming window to avoid aliasing.
But that is a great place to start out.
