Cleaning up noisy audio Of course, it’s always best to record perfect audio at the source. However, some-
times you cannot control the origin of the audio, and it’s impossible to re-record
it, so you are stuck needing to repair a bad audio clip. To that end, the sample you
will work on is a real-world nightmare—a voice-over narration with a horrible
60 Hz hum and a cell phone ringing in the background—but don’t pull your hair
out, because Adobe Soundbooth is up to the task.
1 Open Lesson 13-6.prproj.
2 Double-click audio problem.wav to open it in the Source Monitor. Play the clip,
and notice the 60 Hz hum throughout and the cell phone ringing near the end.
3 Open audio problems fixed.wav in the Source Monitor, and listen to it. Adobe
Soundbooth was used to remove the hum and the cell phone without noticeably
affecting the voice.
4 Drag audio problems.wav to the Audio 1 track on the Timeline.
5 Right-click (Windows) or Control-click (Mac OS) the audio problem clip on the
Timeline, and choose Edit in Adobe Soundbooth > Render and Replace from
the context menu. Soundbooth starts and displays the clip.

Note: Adobe
Soundbooth is not
included with Adobe
Premiere Pro. You must
purchase Soundbooth
separately or as part
of Adobe Creative
Suite CS5. The basics
of Adobe Soundbooth
are included in this
book to demonstrate
its integration and easy
workflow with Adobe
Premiere Pro.
#
Note: A 60 Hz
or 50 Hz hum can
be caused by many
electrical problems,
cable problems, or
equipment noise.
#
Note: You can
also choose to edit
the source file if you
don’t need to keep the
original file. The Render
and Replace command
does not affect the
original file. Rather, it
renders a new copy of
the file and replaces it
automatically on the
Timeline, so the original
file is not changed.
