Gain generally refers to the input level or volume in clips. Volume generally refers to the output level or the volume in sequence clips or tracks. You can set gain or volume levels to make levels more consistent among tracks or clips, or to change the volume of a track or clip. Keep in mind, however, that if the level of an audio clip was set too low when it was digitized, increasing the gain or volume might simply amplify noise. For best results, follow the standard practice of recording or digitizing source audio at the optimum level; this practice allows you to concentrate on adjusting track levels.

You use the Audio Gain command to adjust the gain level for one or more selected clips. The Audio Gain command is independent of the output level settings in the Audio Mixer and Timeline panels, but its value is combined with the track level for the final mix.

You can adjust the volume for a sequence clip in the Effect Controls or Timeline panels. In the Effect Controls panel, you use the same methods to adjust the volume that you use to set other effect options. It’s often simpler to adjust the Volume effect in a Timeline panel.

You control track output levels in the Audio Mixer or a Timeline panel. Although you control track levels primarily through the Audio Mixer, you can also do so using audio track keyframes in a Timeline panel. Because track keyframes represent mixer automation settings, they affect output only if automation is set to Read, Touch, or Latch.

In Premiere Pro CS5.5 and later, the Audio Gain dialog applies the same gain to each of the component audio clips in a merged clip. If individual audio channels need to be adjusted separately, the user can use the clip volume rubberbands on the component clips.

You can adjust the master volume control for an entire sequence with the Normalize Master Track command.

1. Do one of the following:

   • You can 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.

   • To adjust the gain of just one instance of a master clip already in a sequence, select the clip in a Timeline panel.

   • 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 Premiere Pro automatically calculates 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 to 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 option 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.

   Peak Amplitude

   The highest point of the audio waveform of a clip. This item is disabled when multiple clips are selected and will display a “-”.

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.

1. Expand the audio track view by clicking the triangle next to the audio track name.
2. In the audio track header, click the Show Keyframes button , and choose one of the following from the menu:

   Show Clip Keyframes

   Lets you animate audio effects for a clip, including Volume Level.

   Show Clip Volume

   Lets you change only a clip’s Volume Level.

   Show Track Keyframes

   Lets you animate many audio track effects, including Volume, Mute, and Balance.

   Show Track Volume

   Lets you change only a track’s volume level.

3. If one of the Keyframes settings is selected, do one of the following:

   • If Show Clip Keyframes is selected, choose Volume > Level from the pop-up menu at the head of the clip in the audio track.

   • If Show Track Keyframes is selected, choose Track > Volume from the pop-up menu at the head of the clip in the audio track.

     Volume adjustment is enabled by default.

     Note: When you have audio keyframes displayed, you cannot move the audio clip to a different position in a Timeline. Hide the keyframes or collapse the track to move audio clips.
4. Use either the Selection tool or the Pen tool to move the Volume level line up (increase volume) or down (decrease volume).

1. In the Timeline, adjust the volume of a single clip to the desired level.
2. Choose Edit > Copy.
3. Drag a marquee over the other clips you want to change.
4. Choose Edit > Paste Attributes.

1. Select an audio clip in a sequence.
2. In the Effect Controls panel, click the triangle next to Volume to expand the effect.
3. Do any of the following:

   • Enter a value for the level. A negative value decreases the volume level and a positive value increases the volume level. A value of 0.0 represents the original clip’s volume level without adjustment.

   • Click the triangle next to Level to expand the effect options, and then use the slider to adjust the volume level.

     A keyframe is automatically created at the beginning of the clip’s timeline in the Effect Controls panel.

4. (Optional) To change the Volume effect over time, move the current-time indicator and adjust the volume level graph in the Effect Controls panel.

   Each time you move the current-time indicator and make an adjustment, a new keyframe is created. You can also adjust the interpolation between keyframes by editing the keyframe graph. Repeat as needed.

1. Select a sequence that contains audio in two or more audio tracks.
2. Select Window > Workspace > Audio.

   The Audio Mixer panel appears in the central drop zone, with each audio track of a Timeline panel assigned to its own bus on the mixer.

3. Choose Latch, Touch, or Write for all the tracks in the Audio Mixer you wish to modify.
4. In a Timeline panel, for each audio track, click the Show Keyframes button . Then choose Show Track Keyframes, or Show Track Volume from the drop-down menu.
5. Toward the bottom left of the Audio Mixer panel, click the Play button to play the sequence and monitor its audio.
6. Move the volume slider for any audio track up or down to increase or decrease its volume as you monitor the sound.
7. Move the volume slider for the Master track up or down to increase or decrease the volume of the whole mix as you monitor the sound.
