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! -- Mike Silva Tape trading list upon request. SASE required for international mail.
