Can a 1989 Mac IIci decode a 40-minute LP in reasonable time?

By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes.
Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow.

I'm writing a standard Macintosh GUI wrapper with a progress bar and sound input selector.

Beware of System 7.5.1 memory leaks if you allocate large sample buffers in the application heap. Use NewPtrSys instead.
