Optimal PPS Size - Auto Run CD

I have a PPS that's about (45) slides which plays for a little over (3)mins.
It has a wave music file linked. I am making it into a auto-run CD.
Presently it's about 75MB is this too large a file? The wave file is about
50MB. Does the wave file need to be this large, if I use a smaller file will
PP continuously loop it. The PPS plays with no problems on (3) different
computers... Just was wondering about the wave file. If I remember correctly
it's about 5 minutes long. I have another one of the same music that's
smaller and plays for about 1.5 minutes. Can you use the smaller one even
though the show plays for 3 minutes?

Many Thanks!!!

Couple of questions to answer here.

Wav file size is a function of sound quality, number of channels and length
of recording. A Wav file that records silence for 2 minutes will be the
same size as a Wav file that records the minute waltz twice if the quality
and mono/stereo/surround settings are the same.

A larger wav file will take a little longer to retrieve from the CD
(depending on CD speed and a host of minor other speeds). If you want to
reduce the size of the WAV file, you will need to reduce the sound quality,
change it mono, or shorten it's time.

I was a little unclear if the number you said, 75 megs, included just the
PPS file or was everything. If it was everything, then --- the viewer
accounts for about 2 megs, the sound file about 50, this would leave you
with a PPS of about 23 megs. So, you either have a show that is 23 or 75
megs.

In either case, this is a bit large for a 45 slide show. You may want to
look at two different FAQ's for some tips in reducing this file size.

Bill,

First, thanks kindly for your response.

Here's a little better info. The wave file was created using a program
called Total Recorder. I basically recorded the music from the companies
website that I'm doing the presentation for. The first was recorded for
around (5)minutes 50+megs, the second for little over a minute, around
13+megs. I did a test auto CD using PowerLink Plus and the total file size
is about 63megs... So I guess taking off the 50megs for the file size and
the viewer, that leaves about 11megs for the (45) slide show... Does that
sound better?

I guess my question really should have been... If I use the smaller wave
file of 13megs that plays for a little over a minute, will PowerPoint loop
or continue to play it even though the presentation last for (3) minutes?

Many Thanks!!!!!

Sure, you can loop a smaller sound file several times. You will need to set
a couple of options to allow it to do this.

1) Record the smaller sound file.
2) In PowerPoint, Insert | movies and Sounds ... | Sound from File ... |
navigate to the saved Wav file and insert
3) The following varies a little from version to version of PowerPoint, but
the basics are the same. Select the object | SlideShow | Custom Animation |
{select these options} Stop Playing after 999 slides & Continue slide show &
Loop until stopped.

Look at this FAQ for more details:

11 megs for a 45 slide show is still a big large, unless you use an awful
lot of graphics. I would still recommend checking to see if the pictures
can be better optimized (see previous posted links).

A .wav file is a very large file format. If you know the presentation will
be run on a fairly up-to-date computer, consider converting to an .mp3
format. The file size will drop to under 10 megs (most likely under 5 megs).

If sticking with a .wav format, resample to a lower quality. The key issue
is how is it going to be listened to (type of speakers: internal laptop
speakers, desktop speakers, surround sound speakers with high-end sound
card)? Is it background audio and sound effects or narration that needs to
be crisp and clear?
If background music (which it sounds like from your description), open it in
an audio editing program and set the following parameters - this will reduce
the file size to at least 20 megs (or less):
Format = PCM (uncompressed)
Hz = 22,050
Bit Depth = 8
Channels = mono
There is a considerable difference in quality when comparing the two, but
when used as background music in a presentation I doubt anyone will take
notice of the lower quality.

Additionally, PPT can embed a wav file. This is really my primary reason for
using .wav audio files. You can embed .wav files up to 50 megs, but you need
to change PPT's default embed size. Go to TOOLS >> OPTIONS >> GENERAL tab >>
make the "link sounds with a file size greater than _____ kb" to 50,000. Now
insert your (newly optimized) .wav file - it will be embedded in the
presentation and eliminate the need to assure the .wav file is distributed
with the presentation.
