How to embed music in your presentation
If you want the music to be embedded in the presentation you will need to follow a couple of steps.
1. Make sure your music is in WAV format (mp3 files can only be linked and not embedded)
2. Increase the value in the Link sounds with file size greater than box to a value greater than the file size of the MP3 file. For example if the file size is 4.5MB then you will need to include a value higher than 4500. A good general purpose size that should incorporate most song files is 6000 as most mp3 files are less than 6MB. Be careful as some classical music tracks could be longer than this.
The only downside is that the file size of the final file could be quite large.
There is a 50 Mb limit for embedding WAV files. For eample if you had two WAV files of 34 MB the you will be able to embed them, but it would make your file size over 68MB.
