From the developer:
FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). Developers believe that FFTW, which is free software, should become the FFT library of choice for most applications.
You may want to check out more software for Mac, such as Objective Basic, Pleinpot or PLCEdit, which might be similar to FFTW.
