1. One tool that lets you see the audio is you go and click on the square on the very left. This is the speaker icon. It allows you to view the audio. If you want to preview the audio, hit the period key on the keyboard.
2. Markers allows you to preview the audio at certain spots. It is on the right and it has a little arrow. As you drag them across, they will have numbers on them.
3. Two audio effects are delay and backwards. Backwards plays the tune backwards and delay just plays it normally.
4. You create audio to keyframes by right clicking on the audio clip, then go to keyframe assistant, and then go convert audio to keyframes.
5. An example of how you use keyframes and expressions to create audio driven effects are by hitting the u key. Then once you play it, the numbers bellow resets get much bigger.
