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

Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow.
Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes.

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

The 68040 on the Quadra is a monster -- the on-chip FPU executes FFT butterflies in less than 4 milliseconds.

Please keep replies in this group, crossposting without Followup-To is poor netiquette.

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

Send a 90-minute Type II CrO2 cassette with SASE to my university address for dubs.
