About Audio Filters
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 as opposed to 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 Express HD includes a set of audio filters that you can use for equalization,
compression and expansion, adding reverb, vocal cleanup, and noise removal.
Final Cut Express HD uses the Mac OS X Audio Units plug-in format. Audio filter
parameters can be adjusted in real time, so you can make changes to a filter’s settings
while the clip plays back.
