Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes. Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow. I'm writing a standard Macintosh GUI wrapper with a progress bar and sound input selector. -- === Liam Robertson === Dept of Electrical Engineering, Stanford University Computer Systems Lab "Row 14.
