embedded wav file will not play

[djkost]

I created a PP Show ( v.2002 ) with 1 mp3 sound file ( 3 miinutes in length )
linked. This is 26 slides of multiple images with animation and the sound
file ( music ) synced to each slide transition and images within each slide.
It worked perfectly. Sound and show in one desktop file as recommended for
linking.

Now - I copied it all to a 2nd desktop folder and deleted the sound file and
then using the wav'fiying process I converted the sound file to .wav and
successfully embedded it in the 2nd presentation. However, upon testing via
" view show " , the sound will not play at all or occassionally magically
starting up much later than programed to automaticcally ( i.e. sound
commences on slide 3 rather than on initiation of slide 1 ). I can
successfully right click on the sound object embedded and click play sound
and get the music in an individual slide test. I'd like to send the PP show
with embedded sound file and realize it needs other things for portabiblity -
but first I'd like to try to get the embedded sound file to at least work in
sync with the show on my own computer.
Thanks

 

[How to embed a wav file to a Power Point]

I have just received a slide show with 18 slides of pictures and sound.
Instead of inserting the wav file using menu Insert, Movie& sound, Select
the FIRST SLIDE, ADD the wav file into the menu Slide Show, Slide transition,
Modify Transition,
in speed - choose slow
in sound - add your wav file
in Advance slide, select: on mouse click

In all others select the option NO SOUND, in Modify transition.

The slide show will play the song through out all slides after the first
click on the first slide.

I have been through the same problem. In my case, when I changed the MP3
file to a WAV file, the application jumped from 150KB to 38 MB, what is still
unacceptable to be send by e-mail. I don't know how to keep the application
in a small size like everybody else does and send to me. Do you know ?
Thanks, Denisa

Thanks for the input.. I'll try that technique. As for keeping things
small... I am not of much help there. I am burnign all this to CD and
mailing it out to recipeints thorugh I'd rather just e-mail it. 60 MB too
big though.

For small, try lowering the <whatever -- my mind just blanked> Hz of the
file. For example, if it's set to 44100, drop it down to 22050. You may be
able to go lower, just depends on the sound in question.

Also, if it's stereo, make it mono.

Not sure what you just said,,,, but I'm interested in knowing how to
make wav files smaller for including in a PP show. Could you maybe say
this again in dummy language for me. Thank you.

LOL! That's fair, em. Sorry I was about as clear as mud earlier.

Let's see if I can explain.

Sound files have a sample rate. (That's the term I blanked on.) 48,000 Hz is
DVD quality sound. 44,100 is CD, 20,050 is radio, I think, and 11,025 is
telephone.

If you open your sound file in sound editing software, you should have a
"resample" option somewhere. Resample the file to 11,025 Hz and see how it
sounds. It may be fine. Or it may not be. If it's not, hit Undo and try
resampling to 22,050 KHz. If your file started at 44,100, and you resample
to 22,050, you'll halve its size again.

You should also have an option to make the file stereo or mono. Change it to
mono if it isn't already, and that will halve the size right there.
Actually, I'd probably do this first thing before making any other changes.

You can also change the bit-depth from 16-bit to 8-bit. Some sound files do
okay with that change, others become really nasty.

All in all, the amount of sample rate change you can get away with really
depends on your sound file. Same with the bit-depth.

Sound editors:
Audacity http://audacity.sourceforge.net/

Sound Forge Audio Studio (yay! So glad they brought this back!)

Gold Wave http://www.goldwave.com/

Finally--and I can't remember if this was discussed earlier or not--you can
actually save the sound files as MP3 and create fake WAV headers to fool PPT
into thinking the sound is a WAV. You'd use something like CDex
http://cdexos.sourceforge.net/ or RIFFMP3
http://www.studiodust.com/riffmp3.html to do this.

Thank you, Echo. That was helpful.... sunk in a bit better... *s* I
HAD learned before from reading this board about adding that header to
MP3s to make them "pretend wave files" with CDex and now I know how to
compress those wav files using my Windows Sound Recorder. I'm still
trying to figure out the best choices from the Recorder menu for
compressing and still be able to hang on to a reasonable sound
quality... trial and error, I guess.

Another question I have is related to CDex. From what I read about it,
I understand that you can reduce the bitrate of MP3s with the program
but, again, I've found nothing in "dummy" language that lets me
understand it enough to do it. If anyone can kinda give me a
"step-by-step" hint, it would surely be appreciated.

Thank you again... this board is a great way for an old woman to learn
new things... or try, at least..

Cheers !!!

P.S.. thanks for the links.. I'll have a look at those too.
