[comp.sys.mac.hypercard] help with sound transfer to disk

TMARX@auvm.auvm.edu (07/27/90)

I'm new at hypertalk and in a stack that I just created, when I transferred
the stack to a disk, the sound quality of some of the imported sound effects
deteriorated considerably. Why is this and what can I do about it? I use a SE
with 2.5 mb and the stack with Hypercard on it (I need to include it on the dis
k) takes up 774k. Is this the problem?         Tom Marx, American U, D.C.

The sound driver and the floppy disk driver don't like each other.  When you
play sound in a HyperCard stack on a floppy disk it sounds bad.  Putting a
'wait until the sound is "done"' command after the play command helps a bit by
reducing disk access while the sound is playing, but about the only thing I've
ever been able to do to solve the problem completely is to set the volume to 0
(with an XCMD), play the sound, set the volume back to what it was and play the
sound again.  This works because HyperCard keeps the sound in memory, as long
as it's short enough.  Obviously, this is not a very good solution in many
cases, but we does what we cans....
