[SciPy-User] EPD and fast FFT?

Hello All,

Anyone have any hints on speeding up the FFTs on EPD?

I've just started to do some larger 1-d convolutions, and am finding the crunching to be somewhat slow for my data sets (Room Impulse Responses * Audio Files).

I don't seem to think the EPD installation comes set up with FFTW... and, my first thought is that's what's needed to speed things up.

Any advice?

Thanks in advance.



My best,
