Overview of Audio Filters

Filters in Final Cut Pro are always nondestructive, meaning they are applied to clips but not to the media files themselves. You can disable or remove filters at any time, so you can experiment without worrying about altering your media.

The most useful Final Cut Pro audio filters can be separated into five broad categories:

Note: You can install additional third-party Audio Units plug-ins as needed.

Filter parameters can be viewed and adjusted in the Filters tab of the Viewer. Apply an audio filter to an audio clip, then click the Filters tab. You can also double-click a filter in the Effects tab to view its parameters in the Viewer, but you won’t be able to hear any changes you make because the filter is not applied to a clip. For more information about applying filters and adjusting parameters, see Applying Filters to an Audio Clip and Making Real-Time Audio Filter Adjustments.

Filters can be added to any audio clip in a project. You can add filters individually or in groups. When you add filters to a clip, they appear in the Filters tab of the Viewer when that clip is opened in the Viewer. How they appear depends on whether the audio clip in the Viewer is a stereo pair.

Each filter also has a unique set of controls. These controls usually include sliders and number fields that let you adjust the filter’s parameters.
