Chapter 9: Audio
In Adobe Premiere Pro, you can edit audio, add effects to it, and mix as many tracks of audio in a sequence as your
computer system can handle. Tracks can contain mono, stereo, or 5.1 surround channels.
Working with audio
About audio
To work with audio, you must first import it into a project or record it directly to a track. You can import audio clips
or video clips that contain audio.
After the audio clips are in a project, you can add them to a sequence and edit them just like video clips. You can
also view the waveforms of audio clips and trim them in the Source Monitor before adding the audio to a sequence.
You can adjust volume and pan/balance settings of audio tracks directly in the Timeline or Effect Controls panels,
and you can use the Audio Mixer to make mixing changes in real time. You can also add effects to audio clips in a
sequence. If you are preparing a complex mix with many tracks, consider organizing them into submixes and nested
sequences.
If you have Adobe Soundbooth, you can use the Edit In Adobe Soundbooth command to send an audio file to Adobe
Soundbooth for advanced editing.

About audio tracks in a sequence
A sequence can contain any combination of the following audio tracks:
Mono (monophonic) Contains one audio channel.
Stereo Contains two audio channels (left and right).
5.1 Contains three front audio channels (left, center, and right), two rear or surround audio channels (left and
right), and a low-frequency effects (LFE) audio channel routed to a subwoofer speaker.
You can add or delete tracks at any time. Once a track is created, you can’t change the number of channels it uses.
A sequence always contains a master track that controls the combined output for all tracks in the sequence. The
master track’s format is specified in the Default Sequence options of the Project Settings dialog box (choose
Project > Project Settings
> Default Sequence). The Sequence type must be set when creating a new project or
creating a new sequence and cannot be changed once created. The Project Settings dialog box also specifies the
default number of audio tracks in a sequence and the number of channels in the default audio tracks.
