Drew, Powerpoint has a setting for embedding. embedding means the sound file
becomes part of your PPT file. If the sound file is larger than the embedded
setting the file will become linked. if that happens you will need to keep
the sound file with your PPT file if you play it on any other computer other
than the one you created it on. If you end up linking the sound file I would
like to recommend that you put your sound file within the same folder as your
powerpoint file before adding it to the slide. This way when you move your
pressentation and sound file onto another computer the sound will play
properly no matter what drive letter it is located on.
In PP 2003 tools > options > general tab allows you to change the embedded
file size. I recommend at least 1500 kb.
In PP 2007 I have only found one way to open up the option ribbon to change
the embedded sound file size. Maybe someone here has a better way but here
is my way. Place any sound file onto a slide. Now with the sound icon
selected the option ribbon will be avalable. If the ribbon is not selected
select it. Here you will see the maximum sound file size setting. Also set
this to 1500 kb.
If you have a large sound file it is recommended that you link it however if
you know the size and don't want it linked just bump this value up to a
little over the size of your sound file.
If you need a video on how to change the sound embedded file size you can
see one here; Copy and paste this URL. Sorry I don't know how to make the
URL link in this window.
