Extracting and reinserting audio?

[Tim Murray]

I've been given a PPT file that has voice audio but with a low-frequency hum.
I have software that might be able to fix it, but is it possible to extract
audio from a PPT file and replace it later?

I could "play" the slides and record the audio using (for example) Audio
Hijack Pro, but if there is a more elegant extraction method I would prefer
it.

I don't know of a way to extract just the one sound object. However, one
option that should work:

Use File> Save As Web Page which will produce an HTML file along with a
folder with the objects included in a separate folder.


Also, if it is a .pptx you can duplicate the file then use StuffIt Expander
to disassemble the copy into its component parts in much the same way.

Whether using save as Web page or save as > HTML, I got everything except for
the audio objects.

I got a number of audioXX.bin files, where XX is a number, which VLC was able
to play. Thanks for the tip.

I found another solution as well: File Juicer (echoone.com). It takes a
number of file formats and splits them into components. With Juicer, I got a
number of .wav files.
