Solved: PP2007 Embedded narration

[Paul_Hossler]

I have a PP2007 slideshow with the narration embedded within the PPSX. It's kind of big, so I recreated it with the WAV narration files linked in.

As long as the WAV files are in the same folder, as the PPSX, everything's fine.

However,

1. I was looking for flexibility, and there doesn't seem to be anyway to convert embedded to linked, and vice versa (all at once).

2. There doesn't seem to be any way to get to the properties of an embedded WAV file (rt-click will bring up 'Piture Format' and 'Sound Options'. If I want to change the file, the only way seems to be delete the original, and insert new file, or re-record narration.

Is there anyway to get to the properties of these files either via VBA or some menu I'm missing?

I don't think there's any way to change embedded sound to linked or vice versa without delete and re insert.

You can embed mp3 files to get smaller files though.

John, sorry to bother you again, but you had said ...

According to PP2007 help it sort of implies that only WAV files under the adjustable size limit can be embedded



By default, only .wav (WAV: A file format in which Windows stores sounds as waveforms. Such files have the extension .wav. Depending on various factors, one minute of sound can occupy as little as 644 kilobytes or as much as 27 megabytes of storage.) (http://javascript<b></b>:AppendPopup(this,'IDH_ofdefWAV_4_4')) (waveform audio data) sound files under 100 kilobytes (KB) each in size are embedded in your presentation. All other media file types (http://vbaexpress.com/forum/ms-help://MS.POWERPNT.12.1033/POWERPNT/content/HA01230325.htm) and .wav files greater than 100 KB are linked. If you want the .wav sound file to be contained inside the presentation, you can increase the size of the embedded file (http://vbaexpress.com/forum/ms-help://MS.POWERPNT.12.1033/POWERPNT/content/HA01230307.htm#IncDecrease) to a maximum of 50,000 KB (50 megabytes). However, raising this limit also increases the overall size of your presentation and may slow down its performance.



I created a presentation, inserted an MP3, (Insert Sound, Sound From File), and it played.

When I renamed the MP3 on disc, it no longer played, which imples that the was linked. The Sound Format dialog (lower right corner) shows that it's linked.

I have a prog to convert WAV to MP3, so if I insert or record narration and link to the WAV's I can convert them to MP3's

I wrote a macro to delete the WAV links and replace them with links to the MP3 file of the same name, but I still have a whole lot of files in the presentation folder. Would be nice to have a single PPSX file.

Am I missing something, or did I mis-understand?

No, there's a trick to it!

Well ... that was certainly interesting. and keeping with the round-about way of doing things

1. After I .Exported using a hidden method

http://skp.mvps.org/ppt00040.htm

2. I found a free prog to batch convert WAVs to MP3's

http://www.shuangsoft.com/Shuangs_WAV_to_MP3_Converter.asp

3. Used a macro to insert the MP3 as a link.

4. Now if cDex adds the 'WAV' header, I can re-embed the fake WAV sound files

BTW CDex can convert from wav > headered mp3 directly or from wav > normal mp3 . Just check out conversion options. I've also found that mp3 files that don't for some reason work in PPT can be "fixed" by converting to wav and back again.
