Final Cut Pro X: Add audio effects
In addition to enhancing audio using the built-in audio enhancement features, you can take advantage of 64-bit macOS built-in and third-party Audio Units (AU) effects for your audio processing tasks.
Final Cut Pro also comes with an extensive range of custom audio effects and professional Logic Effects, which are digital signal processing (DSP) effects and processors that are used to color or tonally shape existing audio recordings and audio sources—in real time.
Some of the most common processing options include noise reduction, pitch correction, EQs, dynamic processors, and reverbs. Further advanced features include delays, modulations, distortions, bass enhancement, and time-altering processors and utilities. Some custom effects included with Final Cut Pro combine multiple effects to create a particular sound environment, such as a cathedral.
Add audio effects to a clip
Click the Effects button in the top-right corner of the timeline (or press Command-5).
In the Effects browser, select an audio effect.
You can do any of the following to help make your selection:
Preview what an effect sounds like using the audio from the currently selected timeline clip: Move the pointer over the audio effect thumbnail.
Preview changing an effect’s primary control: Hold down the Option key while moving the pointer over the audio effect thumbnail.
Filter the list of effects that appear: Type text in the Effects browser search field.
Do one of the following:
Drag the effect to an audio clip (or a video clip with audio) in the timeline.
Double-click the effect icon to apply the effect to the selected clip.
Change the order of effects
After you apply audio effects to a clip, you can change the order in which they appear in the Audio inspector or the Audio Animation editor.
Copy all of a clip’s effects to another clip
You can copy effects and their settings from one clip to another. This can be especially useful if you’ve made adjustments to effects in a clip that you want to preserve and use with other clips.
Select the clip or clips you want to apply the effects to, then choose Edit > Paste Effects (or press Option-Command-V).
If a clip has more than one effect applied to it, all of the effects and their settings are applied to the other clip.
Copy selected clip attributes to another clip
You can copy selected audio attributes, such as settings and effects, from one clip to another. For example, you can copy pan settings, or any effects you’ve added to a clip, including any keyframe adjustments.
Select the clip or clips you want to apply the attributes to, then choose Edit > Paste Attributes (or press Shift-Command-V).
In the Paste Attributes window, do any of the following:
Apply all audio attributes from the source clip: Select the Audio Attributes checkbox.
Apply individual attributes: Select the checkboxes for the attributes you want to apply.
If you made any keyframe adjustments to the source clip: In the Keyframe Timing section, select either Maintain or Stretch to Fit. If you choose Stretch to Fit, Final Cut Pro adjusts the keyframes in time to match the duration of the destination clip.
