Examining audio characteristics
Audio editing is similar to video editing. It uses most of the same tools, and you 
apply transitions and effects in much the same way.
But audio has some characteristics different from video that affect the way you 
approach editing. In this exercise, you will be introduced to the basics of audio 
editing. You’ll explore more advanced audio-editing topics in Lesson 13.
1
Start Adobe Premiere Pro, and open Lesson 12-1.prproj. Double-click the 
Completed sequence to open that in the Timeline. This is one of the projects 
that you worked on in Lesson 5. This project has multiple audio and video 
files—you’ll examine the characteristics of some of them, as well as a 5.1 
surround sound file added for analysis purposes.
2
Open the audio bin. Double-click Medieval_Sword Swipe – mono.wav to open 
it in the Source Monitor.
A waveform appears in the Source Monitor. The peaks and valleys indicate 
volume levels.
3
Play the audio by clicking the Play button at the bottom of the Source Monitor.

LESSON 12
Acquiring and Editing Audio
4
Scrub the audio by click-dragging your pointer across the waveform in the 
Source Monitor.
5
Experiment with zooming in and out on the waveform vertically (the amplitude) 
by dragging the vertical zoom bar located at the right edge of the Source Monitor. 
This is helpful for observing more detail in the amplitude of the waveform.
