Continuing with the open project, expand the view of the Audio 3 and Audio 4 
tracks by clicking their Collapse/Expand Track triangles.

On Audio 3, right-click the clip Medieval_dialog_hero.wav, and choose Audio 
Gain. Notice the four options for adjusting the gain of the clip:
t
Set Gain to
: The default value is 0.0 dB. This option allows you to set the 
gain to a specific value. This value is always updated to the current gain, 
even when the radio button is not selected and the value appears dimmed.
t
Adjust Gain by
: The default value is 0.0 dB. This option allows you to 
adjust the gain by + or - dB. Entering a value other than zero in this field 
automatically updates the Set Gain to dB value to reflect the actual gain 
value applied to the clip.
t
Normalize Max Peak to
: The default value is 0.0 dB. You can set this to any 
value less than 0.0 dB. For example, this clip has a peak amplitude of –3.3 dB
(as shown in the next figure). Normalizing this clip to 0 db will raise its gain 
by an adjustment of 3.3 db. According to the Adobe Premiere Pro Help 
file, “For a multiple-clip selection, the clip with the maximum peak will be 
adjusted to the user-specified value, while the other clips will be adjusted 
by the same amount, preserving their relative gain differences. For example,

assume clip one has a peak of –6 dB, and clip two has a peak of –3 dB. Since 
clip two has the greater peak value, it will be adjusted by +3 dB to boost it 
to the user-specified gain of 0.0 dB, while clip one also will be adjusted by 
+3 dB, boosting it to –3 dB, and preserving the gain offset between the two 
clips in the selection.”
