Audio filters are used for a variety of purposes, from audio cleanup to special effects. Filter
parameters can be copied, pasted, automated, and adjusted in real time.
The goal of audio mixing and processing is to create a believable sonic environment that
is not distracting. Audio filters can help to remove distracting frequencies, reduce loud
sounds, and add ambience to a sonic space. Generally, filters are much better at removing
components of a mix than they are at adding something that wasn’t in the original
recording. An audio engineer with a thorough understanding of how sound works and
how filters affect sound can produce excellent results with just a few equalizer and
compression filters.
Final Cut Pro includes a set of audio filters that you can use for equalization, compression
and expansion, adding reverb, vocal cleanup, and noise removal. Final Cut Pro uses the
Mac OS X Audio Units plug-in format.
