Save Sounds That are Embedded in PowerPoint Slide Shows

If I receive a PowerPoint presentation that is already in the slide show format, how can I retrieve the music or sound files since they are embedded in the presentation?

Music or other sound objects that are embedded in a PowerPoint slide show can be extracted by converting the show file to an HTML document. This is the format used for Web pages. All the individual parts of the presentation will be extracted separately by PowerPoint and placed in a new folder. Here is how it is done.
