Changing the pitch of an audio clip is relatively simple.

First, highlight the audio clip you want to change the pitch of using the selection tool.

Next, go to the top of the screen, click on “Effects” and then scroll down to where it says “Change Pitch“. Click on “Change Pitch“.

Here is where you will change the actual pitch. The left drop down box lets you choose a starting pitch (what the pitch of the selected clip currently is), the right drop down box lets you choose an ending pitch (what you would like the pitch to be after having been changed). There are other settings, but adjusting the starting and ending pitch is the simplest way to change the pitch of a sound. You don’t necessarily need to know what your starting pitch is. If you’re not familiar with music, the best way to make the pitch higher is choose a note and then that note as a sharp (starting pitch: A ending pitch: A#). The best way to make the pitch lower to choose a note and then that note as a flat (starting pitch: B ending pitch: B♭). Select your starting and ending pitch and then click OK in the bottom left of the dialog box.

All done! After clicking OK the dialog box should disappear and the pitch of your selected clip should be altered.
