I recorded a some audio files on my powerpoint presentation. This was done in two ways: (1) for some slides I used the record narration feature of powerpoint (the audio on each slide was recorded separately) and, (2) for others I used audacity to record the audio, which I imported into powerpoint.

I need to extract the audio file from each slide. I need to send just the audiofiles to someone. Is there a way I can extract the audiofiles?

Thanks

Save your .ppt or .pptx file as "web page" (.htm,.html) with a new name. PowerPoint will create a file with the new file name, and an .htm extension. It will also create a new folder, called yourfilename_files, containing all the embedded objects including sounds in your presentation. Open this newly created folder and you will see all the audio files listed. If your file is in .pptx format, you can also rename it as filename.pptx.zip and you can browse the sound and image files inside the zip file.

Edit: For Mac, you can use File Juicer to extract sounds from your PowerPoint file. See the relevant page for more info.

I did this, however, there are no audio files in the folder. In case it is relevant, I am using the Mac version. Thanks –  user37473 May 18 '10 at 19:21

Thanks Mehper. File Juicer worked well, although not completely. It extracted the audiofiles that were saved using the powerpoint's record narration. It did not extract the audio files that I had recorded in audacity and had been imported in powerpoint. Fortunately, I found these. –  user37473 May 20 '10 at 1:11

Just use 7-zip! (or 7-zip CabTools,if the first isn't working)
Install 7zip and then Right Click to your file->7-Zip->Open as archive.
It also works for .FLV,.DOCX,.XSLX, and for many types of files, which use some compression/archiving. Sometimes it works on EXE files, but it's another story;)
Hope, this helped you.

Use this method without resorting to 3rd-party software:

Duplicate the .pptx file and change the extension to zip.

Unzip the resulting file. You'll see 3 folders and an .xml file.

Open the ppt folder to see more subfolders.

Look in the media folder.

Voilá!
