You probably know this, but if one changes the header info in the
resource fork of the sound file to another number, when you drop the
file into a PT/Logic TimeLine, the playback rate is changed analogous
to slowing or speeding up tape speed. Here's the simple process from
the Soundhack manual
This would be the closest process to changing "tape speed" I know
of. Its instantaneous, reversible and has no adverse affect on
quality. Rob D.
