+/**********************************************************************
+
+ fft.cpp
+
+
+ This class is a C++ wrapper for original code
+ written by Dominic Mazzoni in September 2000
+
+ This file contains a few FFT routines, including a real-FFT
+ routine that is almost twice as fast as a normal complex FFT,
+ and a power spectrum routine which is more convenient when
+ you know you don't care about phase information. It now also
+ contains a few basic windowing functions.
+
+ Some of this code was based on a free implementation of an FFT
+ by Don Cross, available on the web at:
+
+ http://www.intersrv.com/~dcross/fft.html
+
+ The basic algorithm for his code was based on Numerical Recipes
+ in Fortran. I optimized his code further by reducing array
+ accesses, caching the bit reversal table, and eliminating
+ float-to-double conversions, and I added the routines to
+ calculate a real FFT and a real power spectrum.
+
+ Note: all of these routines use single-precision floats.
+ I have found that in practice, floats work well until you
+ get above 8192 samples. If you need to do a larger FFT,
+ you need to use doubles.
