Working with audio
About 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.
To work with audio in Premiere Pro, you must first import it into your project or record it directly to a track. You
can import audio clips or video clips that contain audio. The clips can contain different numbers of channels—mono
(one audio channel), stereo (two audio channels), or 5.1 surround (5 audio channels plus an additional
low-frequency effects audio channel).
After the audio clips are in your 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,
or 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 Audition 2.0, you can use the Edit in Adobe Audition command to send an audio file to Adobe
Audition for advanced editing.

About audio tracks in a sequence
An Adobe Premiere Pro 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 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.
