Oversampling algorithm at FuncShaper

[ortseam]

Hi, Robin!

I use your FuncShaper for many years and I find it the best shaper (not just among the free ones) for me. I like it's sound -
сrisp, transparent and concrete.

I've made some measurements and I saw that aliasing suppression is brilliant. But I also know some other well antialiased products that have same spectral picture but different sound (more vague and dirty) with the same upsampling rate.

As I guess, the difference is in the LP filters used during upsampling and downsampling.

I understand that my next question will be cheeky but yet let me ask: what filters have you used in FuncShaper oversampling algorithm?

Sorry for being so plain at my interest and feel free to point the right place for me to go to

Thanks anyway!

ok, this post is a lot of years old, but since i think it might still be relatable to some people, like me, because i feel the same about funcshaper, i would like to point everyone, who reads this, to this part of rs-met's webpage, which has papers written by the developer, also about filter design. http://www.rs-met.com/tutorials.html

maybe we can find something about oversampling in there as well.
