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:
 Equalization (EQ)
 Gain and normalization
 Dynamics (compression and expansion)
 Noise reduction
 Echo and reverberation
Note: You can install additional third-party Audio Units plug-ins as needed.
Filter parameters can be viewed and adjusted in the Filters tab in 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

on page 164 and “
Making Real-Time Audio Filter Adjustments
