Normalize the Master track

You can set the peak volume level for the master track of a sequence. Adobe Premiere Pro automatically adjusts the fader for the whole master track upward or downward. The loudest sound in the track achieves the value specified. Adobe Premiere Pro scales any keyframes on the master track upward or downward, in proportion to the adjustment made in overall volume.
Note: Adobe Premiere Pro does not allow a volume adjustment that would raise the peak higher than 0 dB.
  1. Select the sequence you want to normalize.
  2. Select Sequence > Normalize Master Track.
  3. In the Normalize Track dialog box, type an amplitude value in the dB field.
  4. Click OK.
