Open up your Basketball with Hoop
Download the sound file of a crowd cheering at the bottom of the page
Create a new layer and name it "Sound"
Go to File/Import to Library
Select the sound file and click "Open"
Your sound should show up in your library on the right side of your screen
Insert a blank keyframe at the same point where the ball goes in the basket
Go down to the Property Manager at the bottom of the screen, go to Sound and select the crowd sheering file
Insert a keyframe 5 frames down from where the sound starts. You will see the sound wave embedded within the frames
The sound never stops - let's fix that
Go to the Edit button on the properties manager at the bottom
Scrolling out, you'll notice that the sound lasts for more than 27 seconds - Let's reduce that.
Click on the line on the top at about the 1 second mark, a handle is created
Click on the line on the top at about the 2.5 second mark, a second handle is created
Pull that second handle to the bottom, this will create a "fade-out"effect.
Do this for the bottom sound window as well
Hit play on the edit window
This is one of a few ways to add sound.
To add sound, go to the sound website, download a file to your computer, Go to File/Import to Library and select your sound file.
