1
Delete the MultibandCompressor effect.
2
Open the clip effect menu by clicking Volume: Level > Channel Volume.
3
Select Left.
4
Drag the yellow line, which now represents the left channel volume, up or down 
to change the left channel’s volume.
5
Click the Show keyframes button on the left side of the audio track, and then set 
it to Show Clip Volume. This causes the track to display the clip’s volume, rather 
than the track’s volume.
6
Ctrl-click (Windows) or Command-click (Mac OS) the yellow line to add a 
couple of keyframes, and adjust them by dragging them left or right along the 
graph line or dragging them up or down.
The advantages of clip-based effect and keyframe editing are that you can get a 
better overall view of the entire clip, and if you want to change only one or two 
parameters, you can easily access them. Some disadvantages are that you can’t 
change the parameters while the clip is playing, setting an exact parameter value is 
challenging, and changing more than a couple of parameters in the Timeline panel 
gets tedious.
Working with the Audio Mixer
There is a big difference in how Adobe Premiere Pro handles layered audio tracks 
and layered video tracks.
Clips in higher-numbered video tracks cover what’s below them on the Timeline. 
You need to do something to those higher video track clips—adjust opacity, create 
PIPs, or use specialized keying effects—to let clips below them show through.
Clips in audio tracks all play together. If you have ten layered audio tracks loaded 
up with a variety of audio clips and do nothing to them in terms of adjusting vol-
ume levels and stereo panning, they’ll all play as one grand symphony (or cacopho-
nous mess).
Although you can adjust volume levels by using each clip’s volume graph in the 
Timeline or Volume effect in the Effect Controls panel, it’s much easier to use 
the Audio Mixer to adjust volume levels and other characteristics for multiple 
audio tracks.

LESSON 13
Sweetening Your Sound and Mixing Audio
Using a panel that looks a lot like a production studio’s mixing hardware, you move 
track sliders to change volume, turn knobs to set left/right panning, add effects to 
entire tracks, and create submixes. Submixes let you direct multiple audio tracks to 
a single track so you can apply the same effects, volume, and panning to a group of 
tracks without having to change each of the tracks individually.
In this exercise, you will mix a song recorded by a choir in a studio:
