| 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. |
