Sounds greater than 100 KB[/h]By default, if sounds are greater than 100 kilobytes (KB) in size, they are
linked (linked object: An object that is created in a source file and inserted into a destination file, while maintaining a connection between the two files. The linked object in the destination file can be updated when the source file is updated.) to your file rather than
embedded (embedded object: Information (object) contained in a source file and inserted into a destination file. Once embedded, the object becomes part of the destination file. Changes you make to the embedded object are reflected in the destination file.) in it. Only *.wav (waveform audio data) sound files can be embedded — all other media file types are linked.
You can change the default for *.wav files to be more or less than 100 KB by changing the number in the
Link sounds with file size greater than box on the General tab (Tools menu, Options command). Although you can raise the maximum size to 50,000 KB, remember that extra size makes the file size of your overall presentation bigger.
Changes made to this setting are not retroactive, so any sound files that were linked before you increased this threshold must be removed and reinserted into your presentation if you want them to be embedded. Correspondingly, any sound files that were embedded before you reduced the threshold must be removed and reinserted into the presentation if you want them to be linked.
Also remember, when your presentation contains linked files, you must copy the linked files as well as the presentation if you give the presentation by using another computer.
