Yes it is. If it doesn't depend on a state, it is simple function composition. Just like saying that you can't compute tan() directly because you have to compose cos and sin with multiplication

I liked it enough that I added oversampling and a DC blocker, hope you don't mind. I will do my best to mirror any updates if you wish.

Cool, thanks.
EDIT: error message: Can't find st-oversampler.jsfx
EDIT2: In the meantime I implemented the HQ mode, I will compare with your solution.

Comparison of the HQ modes.
Input is a sinus tone, 500 Hz, -10 dB.
(click to enlarge, analyser: Voxengo Span)
CPU usage: sault 4x AA is slightly better than HQ mode in my version.
Latency: HQ mode in my version introduces a delay of 9 samples. I will not activate PDC, because Reaper always rounds up to buffer size (256 or 512 samples).

Sorry, my bad, I imported the wrong oversampler library. File updated. Bugfixes courtesy of Tale. He has a slightly tweaked version of his own in the Cockos discussion thread. Our versions will probably start to diverge a little.

No problem, I think I will rename my version to wuff_cs or something, so everybody can take the version he likes.sault wrote: Our versions will probably start to diverge a little.
