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.
