Adjust audio volume levels

When you use footage containing audio, the default audio level for playback is 0 dB, meaning that the level is unadjusted in After Effects. Setting a positive decibel level increases volume, and setting a negative decibel level decreases volume.

Note: Double-clicking an Audio Levels keyframe activates the Audio panel.

The VU meter in the Audio panel displays the volume range for the audio as it plays. The red blocks at the top of the meter represent the volume limit of your system.

For more precision in setting audio levels by dragging sliders, increase the height of the Audio panel.

In the Audio panel, to adjust volume, do one of the following:

To set the level of the left and right channels together, drag the center slider up or down.
To set the level of the left channel, drag the left slider up or down, or type a new value in the levels box at the bottom of the left slider.
To set the level of the right channel, drag the right slider up or down, or type a new value in the levels box at the bottom of the right slider.
