Do we have a fast (using SSE and all if possible) FFT available for kotlin (or java)?

It uses commons-math algotithm, so is available only for JVM. You can also use commons-math algorithm directly

[altavir]

Kmath API is made for streaming transformation. I can add examples if you want.

I'm using commons math for now yeah

[bjonnh]

I don't really need streaming and datasets fit in memory

[bjonnh]

just that I have a lot of them

thanks

Then it is OK to use CM. I was thinking about adding some plain buffer-processing functionality, but I have my hands full right now.
