View audio levels in Final Cut Pro for iPad
The audio meters on the right side of the timeline show the dynamic audio levels of your video during playback. When audio channels in a clip approach the maximum safe volume (0 dB), the vertical meter bars change color from green to yellow to warn you that audible distortion (clipping) may occur.
When the audio level exceeds 0 dB, the bars change from yellow to red, and a clipping indicator above the bars turns solid red until you stop and then restart playback. (You can also manually clear the clipping indicator by tapping it.)
To prevent the audio channels in a clip from clipping, reduce 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 in the loudest sections during playback.
Show the audio meters
In Final Cut Pro for iPad, open a project.
Tap Options in the top-right corner of the timeline.
Tap Appearance, then turn on Audio Meters.
To hide the audio meters, tap Options, tap Appearance, then turn off Audio Meters.
Note: To show expanded audio meters with a numeric clipping indicator, tap Volume in the lower-left corner of the screen.
Correct audio clipping
In Final Cut Pro for iPad, open a project.
In the timeline, select the clip that’s clipping (peaking into the red zone in the audio meters).
Adjust the volume, then play back the clip again to test for clipping.
The clipping indicator shows the peak loudness level in decibels (dB). Reduce the volume so that the peak level (the loudest sound) in the clip is 0 dB.
As you adjust the volume of a clip, sections of the waveform (along the bottom of the clip) that are approaching clipping levels turn yellow. Sections that are clipping turn red.
