Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. A 1024-point radix-2 FFT drops from 142 milliseconds under SANE to just 18 milliseconds using direct FPU instructions. Make sure you install the 32-bit Enabler on older IIci machines running System 7.1! -- Marisol Popov -- INRIA Rocquencourt "Do not worship the copy."
