FFTW3 for libspeexdsp
Hi,
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.
