View audio data
To help you view and edit the audio settings
of any clip or track, Adobe Premiere Pro provides multiple views
of the same audio data. You can view and edit volume or effect values
for either tracks or clips in the Audio Mixer or in a Timeline panel.
Make sure that the track display is set to Show Track Keyframes
or Show Track Volume.
In addition, audio tracks in a Timeline panel contain waveforms,
which are visual representations of a clip’s audio over time. The
height of the waveform shows the amplitude (loudness or quietness)
of the audio—the larger the waveform, the louder the audio. Viewing
the waveforms in an audio track is helpful for locating specific
audio in a clip.
To view a waveform, expand the audio track by clicking the triangle
next to the audio track name.
Click triangle to expand audio track and view audio waveform.
View audio clips
You can view an audio clip’s Volume, Mute,
or Pan time graphs and its waveform in a Timeline panel. You can
also view an audio clip in the Source Monitor, which is useful for
setting precise In and Out points. You can also view sequence time
in audio units instead of frames. This setting is useful for editing
audio at smaller increments than frames.
Do any of the following:To view the audio waveform of a clip in a
Timeline panel, click the triangle to the left of the audio track
name and click the Set Display Style icon 
under the
Toggle Track Output icon 
. Then
choose Show Waveform.
To view an audio clip in the Source Monitor when
the clip is in a Timeline panel, double‑click the clip.
To view an audio clip in the Source Monitor when
the clip is in the Project panel, drag the clip to the Source Monitor.
If a clip contains video and audio, you can view its audio in the
Source Monitor by clicking the Output button 
and
selecting Audio Waveform.
View time in audio time units
In the Audio Mixer, Program Monitor,
Source Monitor, or Timeline panel, choose Show Audio Time Units
from the panel menu.
