PowerPoint linking to narration sound file

I am having a lot of trouble using a linked sound file as a background for an entire PowerPoint slide show. Anybody ever do this?

I was able to successfully do this with an embedded file, but I have files that are over the 50M limit for embedded files.

The files are too big to embed, so I linked a file. The linked file will play as a sound on the slide it’s attached to but I can’t get it to continue playing when I move to the next slide. The dialog boxes for animations are different for embedded vs. linked files, and the option to continue playing for x slides isn’t there with the linked file.

The sound file is a soundtrack from a video of a trainer, and I want to use it as the background for his slides in PPT.

My first choice would be to find a way to compress the sound file, e.g. to an MP3. When streaming a song if you hit a lull in the connection, you could have nada.

However, if it’s like a regular sound file, the option is to go to

Slide where it starts
Click Custom Animation
Double Click on the item on the right hand side

That brings up the choices for Start Playing/Stop Playing under the Effect tab. Set the number of slides you want.

I did this to reduce size, but PPT can’t read MP3 files, just WAV files. There is a utility available that puts a WAV wrapper on an MP3 file, and it seems to work here for linked files, but not embedded files. The smallest file I have is a 12M MP3, which is 90M as a WAV.

I am not streaming a file over the network, it is linked to a file in the same disk directory as the PPT file.

I did all this for embedded file, but this only works for embedded files, not linked files. As you see in the OP, the dialog is different.

Have you thought of converting the Powerpoint presentation to Flash, and then add in the audio?

No. Have never generated a Flash animation, don’t have the developer’s kit. How big is the startup effort?
