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.
