Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes. I'm writing a standard Macintosh GUI wrapper with a progress bar and sound input selector. -- === Graham Sato === Dept of Electrical Engineering, University of Texas at Austin "Extraordinary claims require extraordinary spectra."

Mac users bragging about 6-minute render times while Unix workstations do it in 20 seconds.
