MP3 files cut off at end in PowerPoint

[David Fox]

I'm creating a presentation in Mac Office for OS X. I'm using MP3 for a
bunch of narration files. I've noticed that around the last 1/2 second of
sound is not playing on most of the files. The files themselves are fine,
but double-clicking on the sound icon in the presentation, or letting the
presentation run, results in the same behavior each time.

I did some experiments using different compression rates. It seems that the
lower the compression rate, the more of the end is cut off (e.g.,
32kbps/24Khz is pretty bad, 128kbps/44Khz is hardly noticeable). So, my
assumption is that the last chunk of data is being ignored. For lower bps
files, this equates to 1/2 a second. For higher ones, it's a fraction of
that.

I also tried compressing them in different programs (Itunes, Cleaner) and it
doesn't make a difference.

When I transfer the presentation to a PC, all the files play fine.

Any ideas? Sure sounds like a bug.

Please reply to me directly as well as to the newsgroup.

Thanks,

David

Hi

Try trashing PowerPoint's preferences. If that doesn't fix it (which it
probably won't but it's at least worth a try) then use the feedback feature
under the Help menu to let Microsoft know about the problem.
