Final Cut Pro X: View and correct audio levels
The audio meters show the audio levels of clips in Final Cut Pro and warn you if a particular clip or section of a clip reaches peak levels, which may result in audible distortion.
When an audio clip is approaching peak levels during playback, the level color changes from green to yellow.
When an audio clip exceeds peak levels, the level color changes from yellow to red, and the peak indicator turns red for the respective audio channel or channels. The peak indicators are reset when you stop and start playback.
To avoid having clip volume exceed peak levels, adjust the volume. Although the proper level for a clip depends on the mix, it’s important to make sure that the combined level for all concurrent clips doesn’t exceed 0 dB during the loudest sections.
Show the audio meters
To show the larger meters, do one of the following:
Choose Window > Show in Workspace > Audio Meters, so there’s a checkmark next to the menu item.
Click the audio meters icon below the viewer.
You can drag the edges of the meters to see an expanded view with additional information.
To hide the larger audio meters, choose Window > Show in Workspace > Audio Meters, or click the audio meters icon below the viewer.
Note: The number of audio meters you see depends on how many channels are configured for the clip you’re playing. For example, when you play back a surround clip in the browser, six surround audio meters are displayed, but if you drag that same clip into a stereo project in the timeline, Final Cut Pro automatically mixes down the surround audio into stereo, and only two audio meters are displayed. For information about changing a project from stereo to multichannel surround sound, see Modify a project’s settings. For information about channel configurations, see Configure audio channels.
Reset and correct peak levels
Note: If you add a clip with mono audio to a stereo project, Final Cut Pro plays the single mono audio in both left and right channels, visible in the stereo audio meters for the project.
