|          Third-party FFT (fast Fourier transform) code
 | |
| 
 | |
| This directory contains the third-party one- and two-dimensional
 | |
| fast Fourier transform and related sinusoidal transform code written
 | |
| by Takuya Ooura.
 | |
| 
 | |
| Depending on your needs, there may be better choices than this
 | |
| package, e.g.:
 | |
| 
 | |
| 1.  David Talkin has written a fast and flexible radix-2 FFT class:
 | |
|       google3/speech/dsp/fft.h
 | |
| 
 | |
| 2. fftw (http://www.fftw.org/) likely offers speed advantages over the
 | |
| routines in this package and undoubtedly has a much larger user base.
 | |
| However, it's a much bigger and more complex package.
