Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes. By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. Make sure you install the 32-bit Enabler on older IIci machines running System 7.1! -- Renata Watanabe | rwatanabe@pipeline.com PGP Key fingerprint: 56AA C294 4C6E B152 "Keep the channels open."

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