By default Premiere Pro plays the audio when you scrub any clip or sequence containing audio in the Source Monitor, Program Monitor, or the Timeline panel. You can change this setting if you prefer silent scrubbing.
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 Track 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 the Timeline panel.
You control track output levels in the Audio Track Mixer or the Timeline panel. Although you control track levels primarily through the Audio Track Mixer, you can also do so using audio track keyframes in the Timeline panel. Because track keyframes represent mixer automation settings, they affect output only if automation is set to Read, Touch, or Latch.
You can adjust the gain for an entire sequence with the Normalize Master Track command.
You can adjust the gain of a master clip so that all instances of the clip added to the 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 the 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.
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.
You can set the peak volume level for the master track of a sequence. Premiere Pro automatically adjusts the fader for the whole master track upward or downward. The loudest sound in the track achieves the value specified. Premiere Pro scales any keyframes on the master track upward or downward, in proportion to the adjustment made in overall volume.
Adobe Premiere Pro does not allow a volume adjustment that would raise the peak higher than 0 dB.
You can adjust the volume level of a whole clip or track, or have the volume change over time using the rubber band in an audio track of a Timeline panel.
- In the audio track header, click the Show Keyframes button , and choose one of the following from the menu:
If Show Clip Keyframes is selected, choose Volume > Level from the drop-down menu at the head of the clip in the audio track.
If Show Track Keyframes is selected, choose Track > Volume from the drop-down menu at the head of the clip in the audio track.
Volume adjustment is enabled by default.
When you have audio keyframes displayed, you cannot move the audio clip to a different position in the timeline. Hide the keyframes or collapse the track in order to move audio clips.
- Use either the Selection tool or the Pen tool to move the Volume level rubber band up (increase volume) or down (decrease volume).
If you want the Volume effect to change over time, place the current-time indicator at the location for each change, click the Add/Remove Keyframe button in the audio track header, and drag the keyframe up (louder) or down (quieter).
This procedure pastes all effects and attributes of the first clip selected, not just its volume settings.
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.
- (Optional) To change the Volume effect over time, move the current-time indicator and adjust the volume level graph in the Effect Controls panel.
You can use this procedure when automation isn’t applied to a track. If levels vary over time because track automation keyframes are already applied, you may be able to adjust the track level uniformly by sending it to a submix and setting the submix level.
Muting doesn’t affect pre-fader items such as effects and sends. Also, the state of the Mute Track button is subject to the automation settings in effect. If you want to silence track output completely, click the track’s Speaker icon in the Timeline panel.
You can set volume levels of two or more audio tracks, relative to one another, using the Audio Track Mixer. For example, you can raise the volume of a narrator’s voice on one audio track while simultaneously decreasing the volume of the background music on another track. Also, you can raise or lower the overall volume level of the complete mix, which contains the audio from all tracks selected. The Audio Track Mixer lets you make these adjustments in real time while you listen to playback from desired tracks. By default, the Audio Track Mixer volume adjustments made for each audio track are saved in Track Volume keyframes visible on that track in the Timeline panel. Volume adjustments made for the whole mix are saved in Track Volume keyframes visible in the Master audio track in the Timeline panel.
