> Attached is a patch which enables FFTW3 to be used by libspeexdsp. Using
> SSE, the FFT code is more than twice as fast, and it's 50% faster even
> without SSE. To enable the library, you'll need to call configure with
> '--with-gpl-fftw3'.

> Based on the benchmarking we did, this also changes the default FFT to
> smallft for floating point implementations when not using FFTW3.
