- [Instructor] In addition to video,
we can also add audio to our PowerPoint presentations.
Now, we can add audio using the insert menu.
And if we go over to media, you'll see video,
audio, and screen recording.
Now, with audio we can either use an existing audio file
or we can record our own.
So, if I select audio on my PC,
you'll see we have a number of different audio files,
but actually I'm going to record my own.
So, let's go into audio, record audio.
Now, this gives me a little dialogue here,
that I can use to name the sound.
And so, I'm just going to call this Drone Market.
And I already have my microphone setup.
So, I just need to hit the red button to start recording.
The drone market is expanding by 25% per year.
And then I hit stop, and OK.
And this little speaker icon shows up,
and it's just another object in the scene,
and we can make that bigger so that way we can see it
a little bit better.
And once it's in the scene,
we'll also have audio tools here.
So we can format the audio so that way
we can make that icon more apparent.
But I'm going to leave that alone and go over to playback.
Now, this is very similar to what we have with video.
We can trim the audio and in this case,
I did have a little bit of space before I started talking.
So if I hit play,
"the drone market,"
you'll see that up to about here is silence.
So I'm going to trim that off here,
and then also trim it off towards the end.
Now, if you look closely, you can see the wave form here.
And so that can be used to guide
where you create your edits.
So I'm going to click OK.
And we can also fade in and fade out.
We can change the volume,
and we can change where it starts.
So I'm actually going to make this automatic.
We can also play it in the background.
So if you have a piece of music
that is going to be constantly playing
that you would talk over or something like that,
you can do that.
Now this is not something that we would do for that.
So let's go ahead and go to slideshow,
from current slide, and see how our audio sounds.
The drone market is expanding by 25% per year.
And there we go.
So audio is pretty easy to bring into your presentations.
Typically you'll do stuff like music or sound effects,
but you also can do narration.
