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. Anyone running this on a Quadra 840AV with the 68040? -- Diego Moreau | dmoreau@kiae.su PGP Key fingerprint: 6D48 9997 3A35 D4C6 "Keep the channels open."
