Review answers

1 Using the Audio Mixer, you can easily adjust the audio balance and volume for

diff erent tracks in your project. You can refi ne the settings while listening to audio

tracks and viewing video tracks. Each track in the Audio Mixer corresponds to an

audio track in the Timeline or Sceneline, and is named accordingly. You can access the

Audio Mixer by clicking the Mix Audio button or choosing Window > Audio Mixer.

2 Each clip in the Adobe Premiere Elements Timeline has a yellow volume graph that

controls the keyframes of the clip. To add keyframes, you Ctrl-click the line. You must

have at least two keyframes with diff erent values to automatically change the volume

level of an audio clip. You can also use the Audio Mixer to set keyframes to change the

volume of your audio clip over time.

3 First, select the clip that contains the eff ect you want to adjust in the Timeline.  en, in

the Eff ects view, click the Edit Eff ects button. In Properties view, expand the property

by clicking the triangle next to the property name (if available), and then drag the

slider or angle control.

4 Normalization boosts the audio volume of all samples of an audio clip the same

amount, stopping when further volume increases would produce distortion in the

loudest sections of the clip. Compression increases the volume of lower-volume

regions while ignoring the loudest regions. Normalization is a tool that can be used

nearly universally to boost volume, while compression should be used only when

necessary to make a specifi c audio track more distinct.
