DESCRIPTION

This is an implementation of cross synthesis using FFT's.

INITIALIZATION

isize - This is the size of the FFT to be performed. The larger the size the better the frequency responce but a sloppy time responce.

ioverlap - This is the overlap factor of the FFT's, must be a power of two. The best settings are 2 and 4. A big overlap takes a long time to compile.

iwin - This is the ftable that contains the window to be used in the analysis.

PERFORMANCE

ain1 - The stimulus sound. Must have high frequencies for best results.
ain2 - The modulating sound. Must have a moving frequency response (like speech) for best results.
kbias - The amount of cross synthesis. 1 is the normal, 0 is no cross synthesis.amp

EXAMPLES:

        a1    oscil    10000, 1, 1
        a2    rand     10000
        a3    cross2   a2, a1, 2048, 4, 2, 1
              out      a3

If ftable one is a speech sound, this will result in speaking white noise. ftable 2 must be a window function (Gen20).
