now that we've added some audio files to
our presentation we need to edit them a
little bit so they'll play back
correctly on the first slide I added
some intro music but the song is over a
minute long and I really only need a few
seconds to fix this we'll need to trim
it make sure that the audio icon is
selected and then go to the playback tab
and trim audio
and now you can use the green and red
markers to change the start and end
points
to preview it click the play button
and I'm going to be adding a fade in and
fade out so when I'm done the beginning
and end will sound a lot smoother
and you can adjust the fade in and fade
out on the playback tab I'm going to do
Oh point seven five seconds for the fade
in and I want the fade out to be a
little bit longer so I'll do three
seconds if you want to be able to jump
to a specific point in the song you can
add a bookmark click on the timeline
where you want the bookmark to be
and then click add bookmark and this
little circle will appear and during
your presentation you can just click on
it to jump to that spot
if I played the slideshow right now I
would have to click on the audio icon to
start the music
but I would prefer if it started playing
automatically you can change this by
going to the audio options group on the
playback tab and where it says start on
click you can change this to
automatically
and there are some other options that
you can change here you can have the
audio file loop continuously until you
stop it you can rewind it after it's
done playing you can hide the audio icon
and you can adjust the volume
and now I'm going to start the slideshow
to test the intro music
and it starts playing automatically and
it fades out nicely
if you want to change the appearance of
the audio icon just select it and go to
the format tab and here you can make any
kind of adjustment that you want or you
can even use one of your own pictures in
the adjust group click the change
picture command
and then find the picture that you want
to use and click insert
then you can resize it if you want to
and I'm also going to change the color
so it matches the slide
Audio can add a lot of excitement to
your presentation and by using the
format and playback tabs to customize it
you can make it even more impressive
