Enhance audio in Final Cut Pro
Final Cut Pro includes several powerful tools for automatically analyzing and enhancing the
audio in your projects, including:
• Loudness: Improves the main audio signal and makes it more uniform.
• Background Noise Removal: Reduces background noise.
• Hum Removal: Reduces common electrical hum noise at either 50 or 60 Hz.
All enhancements are designed to correct most common audio problems automatically or
with minor adjustments.
You can let Final Cut Pro analyze audio and adjust these problems in your audio clips
automatically, or you can make manual adjustments in the Audio Enhancements section of
the Audio inspector. You can also analyze and fix audio problems when you import a clip.
(See
Audio analysis options in Final Cut Pro.)
Note: When you import a clip with the “Analyze and fix audio problems” import option
selected, only severe audio problems are corrected. If the clip contains moderate
problems, these appear in yellow next to Audio Analysis in the Audio Enhancements section
of the Audio inspector after the clip is imported. To correct these problems, you need to
automatically enhance audio in the Audio inspector.
1. In Final Cut Pro, select an audio clip or a video clip with audio in the timeline.
Important: Audio enhancement works on the component level, not the clip level. If your
audio clip has more than one audio component (for example, a dual mono clip), select
an individual component, then proceed with the enhancements.
2. Do one of the following:
• Choose Modify > Auto Enhance Audio (or press Option-Command-A).
• Click the Enhancements pop-up menu below the viewer and choose Auto Enhance
Audio.
• In the Audio inspector, click the Auto Enhance Audio button next to Audio Analysis
in the Audio Enhancements section.
