Final Cut Pro: How To Change Audio Levels in the Viewer

The Viewer has audio controls that allow you to control audio levels. When you open the Audio tab in the Viewer, you will be able to view the audio level overlay and pan overlay. This is a good way to edit audio that was recorded using the Audio Mixer in Final Cut Pro. This guideline will go over the five audio controls that are accessible through the Viewer and the affect that these controls have on your clip.

Level Audio Controls

You can adjust audio levels using the Level slider, which is located at the top of the Audio tab. By dragging the slider to the left or right, you can decrease or increase the audio levels. Next to the Level slider is the Level field. You can enter numeric values into the Level field to change the audio levels. The Level field allows you to enter negative numeric values, as well. To do this, type a minus sign before the number.

Audio Level Overlay

You can also change audio levels by dragging the audio level overlay. To change audio levels by dragging the audio level overlay, place your mouse over the audio level overlay. The audio level overlay will appear as a pink line in the Viewer. Your mouse pointer will change to an Adjust Line Segment pointer when you are over the audio level overlay. To decrease or increase the audio levels, all you have to do is drag the audio level overlay down or up. While you are dragging the audio level overlay, a box will appear on your screen that will display a numeric value of the new audio level.

Modify Menu

The Modify menu can also be used to change audio levels in the Viewer. In order to use the Modify menu to change audio levels, you will need to position the Timeline's playhead over the clip whose audio level you wish to change. Once that is done, go to Modify and then Audio. The submenu will display Gain items. The Gain items are various figures that are used to modify the audio level. When you choose a Gain item, the audio levels will automatically be changed.

Keyboard Shortcuts

The final way to change audio levels in the Viewer is to use keyboard shorts. To increase the audio level by 1 db, press Control and =. To decrease the audio level by 1 dB, press Control and -. To increase the audio level by 3 dB, press Control and =. To decrease the audio level by 3 dB, press Control and [.

Affect of Audio Controls

If you have no audio keyframes set in your clip, the audio levels for your entire clip will be changed when you use the Level slider, Level field, or when you drag the audio level overlay. If you do have audio keyframes set in your clip, the Level slider and Level field will only change the audio levels of the keyframe that the Viewer playhead is positioned over.
