Normalize one or more clips

  1. Do one of the following:

    • If you want to adjust the gain of a master clip so that all instances of the clip added to a Timeline panel have the same gain level, select the master clip in the Project panel.

    • If you want to adjust the gain of just one instance of a master clip already in a sequence, select the clip in a Timeline panel.

    • If you want to adjust the gain of more than one master clip or clip instance, select the clips in a Project panel or sequence. In a sequence, shift-click the clips to select them. In a Project panel, shift-click to select contiguous clips, or Ctrl-click (Windows) or (Command-click (Mac OS) to select non-contiguous clips.

  2. Choose Clip > Audio Options > Audio Gain.

    The Audio Gain dialog box opens and Adobe Premiere Pro automatically begins calculating the peak amplitude of the selected clips, reporting the calculated value in the Peak Amplitude field. Once calculated, this value is stored for the selection. You can use this value as a guide for the amount you should adjust gain.

  3. Select one of the following, set its value, and then click OK:
    Set Gain To
    The default value is 0.0 dB. This option allows the user to set 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. For example, when the second option, Adjust Gain By, is used to adjust the gain by -1 db, the Set Gain To value would also update to show the resulting gain level. When the Audio Gain dialog is opened for selected clips that have already had their gain adjusted, the current gain value is displayed in this field.

    Adjust Gain By
    The default value is 0.0 dB. This option allows the user to adjust 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.

    Normalize Max Peak To
    The default value is 0.0 dB. Users can set this to any value below 0.0 dB. For example, a user may want to allow for headroom and set this to -3 dB. This normalization option adjusts the maximum peak amplitude in the selected clips to the user-specified value. For example, a clip with a peak amplitude of -6 dB will have its gain adjusted by +6 dB if Normalize Max Peak To is set to 0.0 dB. 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.

    Normalize All Peaks To
    The default value is 0.0 dB. Users can set this to any value below 0.0 dB. For example, a user may want to allow for headroom and set this to -3 dB. This normalization option adjusts the peak amplitude in the selected clips to the user-specified value. For example, a single clip with a peak amplitude of -6 dB will have its gain adjusted by +6 dB if Normalize All Peaks To is set to 0.0 dB. For a multiple-clip selection, each clip in the selection would have its gain adjusted by amounts necessary to boost them all to 0.0 dB.
