To embed sound into PowerPoint 2007, the sound file has to be in a “.WAV” format and not “.MP3”. If it is an mp3 file, the file will be linked rather than embedded. PowerPoint has no way to perform this conversion so to convert your .mp3 to a .wav file you will need a sound editing program.
Important. Sounds that are already in the slides will need to be reinserted, or will not be considered embedded.
Select the slide you would like the sound to be played on, or to start laying from, then follow these steps.
You’re done! This allows you to be able to send your presentation to colleagues without having to also send the sound file also, the sound is now included in the presentation.
If the file still isn’t being embedded its either not in .WAV format or the file size is too large.
To change the maximum file size allowed
1. Go to PowerPoint Options
2. On the Advanced tab, go to the “Save” section
3. Increase the Link sounds with file size greater than ___ Kb setting to a size just larger than your largest sound file, up to 50,000 KB (50 MB).
4. Click OK.
