#X text 10 357 This is the form of pulse train used in the Phase Aligned
Formant (PAF) algorithm. It has the neat property that its amplitude
spectrum drops off as a perfectly exponential function of frequency.
This algorithm is protected by French and US patents. contact Vincent
Puig to learn what restrictions may apply.;
#X text 11 457 On the other hand \, there are rumors that exp(-X*X)
actually sounds better than 1/(1+X*X). To compute exp(-X*X) efficiently
you will want to employ tabread4~ with a stored bell curve. I don't
want to know you're doing this. However \, the first Pd user who e-mails
me the correct formula for the output spectrum wins a free CO2 fire
extinguisher.;
