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. Anyone running this on a Quadra 840AV with the 68040? -- Astrid Sato "There are 14 nodes and only 10 countries. Count again."
