ar cross2 ain1, ain2, isize, ioverlap, iwin, kbias
This is an implementation of cross synthesis using FFT's.
isize - This is the size of the FFT to be performed. The larger the size the better the frequency response but a sloppy time response.
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.
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.
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).
