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. Make sure you install the 32-bit Enabler on older IIci machines running System 7.1! -- Natalia López *PLONK* filter active for trolls.
