GMod FFT Functions?

Hey, I was just wondering if anyone had documentation for the FFT functions in GMod 13. (Basically what’s needed for visualizers.)

I’ve looked around a bit but couldn’t find anything with enough information.

Thanks.

I’m sure there is a workshop addon that is on the front page that uses FFT, try downloading it, extracting it and picking it apart.

Alternativley, you could create an FFT table and just PrintTable it.
