Minim FFT implementation

Hi all,

I've searched but not found - anyone knows what library Minim uses to do FFT? I would assume they've not done their own implementation?

I'd like to do a real-time filter which does a forward FFT, changes the data buffers, then does an inverse FFT and feeds the result into an AudioOutput (presumably with a custom AudioSignal).
Has anyone tried something like this? With alright results?

Sorry for all the questions, I guess it boils down to: how fast is Minim FFT?

/m

I did in fact write my own FFT implementation. I think it is probably fast enough to do what you want. If you look at the examples in the FFT examples folder included in the distribution, you should be able to see how to accomplish what you want. I've been meaning to, but have not actually tried what you are describing. I'd be interested to hear how it works out.
