Re: Version 2003

I have four slides. Advance slide on click. Start with previous ......
#1 "no sound" selected, no tune, no audio ......
#2 tune "A" repeat till end of slide (insert sound method)
#3 tune "B" loop until next sound (transition loop method)
#4 tune "B" adopted from #3 (i.e. sounds across slides) plus action button
to stop previous sound.

Everything is fine and behaves exactly the way I want it going FORWARD.

However, I have a problem going BACKWARD "tunewise." From #4 to #3 is fine
because both have tune "B." When #3 is displayed, the tune restarts from the
beginning and I have expected that.

Problem: From #3 to #2

Two effects when #2 was displayed:-

(1) No tune if I selected stop previous sound even though I used the insert
sound method.
(2) Tune "B" (instead of tune "A") if I selected no sound.

I want tune "A" for slide #2 when going backward.

Please be reminded that I use two different methods for #2 (insert sound
i.e. animation) and #3 (transition loop) respectively. Is this the culprit?
Can't have interface between two methods?

Please note that this is my first experiment on applying sound to slides.
Please bear with me.

Appreciate advice, guidance, comments ......

When you go backwards, PPT goes to the *end* of the slide. You need to go to
the slide before and then move forward to slide #2. This is often
accomplished with a hyperlink to a dummy slide (set a 00 second auto
transition) before the real slide.

Unfortunately, I can't find the FAQ on this -- I think it explains a bit
better.

Thanks Echo and Steve. I am glad I asked. I heard you and I read the FAQ,
but I am still confused. Going backward **did work** for slide #4 to #3
(same tune). Why is this problem not consistent? Do we only have problems
going backwards when the tune is different? Is it because I use the
"transition loop" method for slide #4 and #3? Is there an explanation for
all this? Just wondering. Don't want to spend much time on this as it is a
known problem. I prefer to focus on the following. Appreciate any insight.

Between the two methods (insert sound and transition loop), I vote for
transition loop based on my little experiment.

I have two problems with the insert sound method but not with the transition
loop method.

(1) Using the same WAV file and the same hardware, the repeat of the tune
sounded abrupt with the insert sound method. I could tell when the repeats
happened. With the loop method, it was so smooth.

(2) I sent the ppt file (described in my first post) as an email attachment
to my own email address at yahoo.com. When I opened the attachment and ran
the show using the same PC where the wav files were located, I had no problem
hearing both tunes. When I used a different PC (where there were no wav
files) to open the attachment and ran the show, I only heard tune B but not
tune A. As I described earlier, tune A was included using the insert sound
method whereas tune B was included using the transition loop method.

I wonder why the above happened. Appreciate your comments. What is the
vote among MVP's? It is unfortunately that transition loop method is limited
to wav files.

Thanks!

The sounds are behaving differently because of the two different insertion
methods.

Since the transition method does what you want, I'd recommend you go ahead
and use it. The one drawback is only WAVs can be added to transitions. So if
you're using an MP3, you'll need to convert to WAV.

Also, WAVs inserted on the slide will be embedded only if they are smaller
than the size indicated in Tools|Options|General| "link sounds with file
size greater than XXX kb." You can put up to 50000 in there, which is ~50MB.
You have to do this before you insert the sound on the slide, though.
http://www.echosvoice.com/gotchas.htm (head to Sound Advice) has quick
straightforward info on this in particular. Sounds/Movies don't play, images
disappear or links break when I move or email a presentation
http://www.pptfaq.com/FAQ00155.htm has information on all kinds of other
links if you're interested. <rant> Grrrr. I always use the keywords "links
break" (without the quotation marks) to look for this FAQ on the PPTFAQ
site. And of course the results are NOT showing it today. I'm beginning to
really dislike Google. I don't know what they're doing to individual site
searches, but they're increasingly unreliable, and, well, they pretty much
suck. And I can't even find anyplace at Google to complain! </rant>

I can't remember if there's a limit to the size of WAVs added into
transitions or not.

Echo,

Thank you so much for helping me solve my sound problems. I enjoyed reading
"sound advice" on your web site. It is rich and easy to understand and more
importantly it answers my questions (asked and to be asked).

For my experiment, tune B (WAV file) played while tune A (WAV file) didn't
when I opened the email attachment (PPT file) on another computer. Guess
what, tune B was 99.5 KB while tune A was 103 KB. Bingo!! Tune A was above
the default. It was so amazing that I accidentally picked the two tunes with
such good sizes for an experiment. I knew nothing about size prior to this.
For some reason, I always seem to have an affinity with anomaly and that's
why I am able to find bugs that others may not find and I learn a lot because
of this. Of course, without an expert like you helping me, I won't learn so
much.

Thanks again for your guidance.

I think this is the one Echo was looking for:

Thanks, Steve. I read the article and I have a follow-up post.
