By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes. 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! -- Matthias Lindqvist Tape trading list upon request. SASE required for international mail.
