"beep" is not exactly broken in Mac OS X, but it does have issues. In
particular:
1. "beep n" where n > 1 sounds like it only beeps once.
2. If the host application quits immediately after the beep, you
probably won't hear it. (This generally only applies to applets and
osascript.)
One problem is that "beep" plays the sound asynchronously -- that is,
the call returns immediately, and the system plays the sound on a
sub-thread while you're doing whatever. This is true even in Mac OS 9,
but X is a lot more efficient about it, so multiple beeps will pile on
top of each other so closely they sound like one.
The other problem is that sound output channels are considered
application resources in Mac OS X and are released when the application
terminates, even if they're not done playing. So the application starts
to play a beep, then terminates, and the sound gets cut off. If you're
lucky, you might hear a little click.
The workaround in either case is to put a little delay after each beep
to give it a chance to play. Neither problem applies to "say" because
it works synchronously -- the call doesn't return until it's done
speaking.
