Hello
I don't know much about this topic, but im interested in what can be made on a sample to sample level in pd. Does anyone know what different things can be done? I know you can make custom filters, but I was wondering if anyone could point me to a place where I could learn about this topic

You will see that @katjav chips into that thread.
You will find more information from her here....
https://www.katjaas.nl/home/home.html .... with great explanations of the Fourrer Transform among other things.... and her site will help understanding of the maths involved.

Also.... fft.zip

thank you very much
The first part looks useful... the fft part is not the same "per-sample" thing right?

@mezko I am fairly certain that in Pd fft objects will be used in small sample filters so an understanding is useful.
It is not my subject so I could be talking rubbish....
However..... https://www.katjaas.nl/minimumphase/minimumphase.html

ok thank you very much again... I think it looks complicated so not sure I will understand what's on the site, but will save the link for maybe later Do you know what other applications you can use this thing for except for filters?

Ive got a bunch of files maybe for what you need I did some files for adjusting all the numbers in an array because everyone always wants to multiply the entire set..

@willblackhurst thank you! I actually found all your code on that side a couple of days ago. The array zoom file was very helpful to me... although I don't understand how to transfer changes from the zoomed array unto the original one...

well the zoomed array probably has less numbers left to right and isnt any different really, its just a shorter list so it looks larger.
