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. Make sure you install the 32-bit Enabler on older IIci machines running System 7.1! -- Elaine Moreno Tape trading list upon request. SASE required for international mail.
