About Soundtrack Pro
Soundtrack Pro provides a streamlined workflow for editing everything from individual audio files to large multitrack sound projects, including synchronizing audio and video, editing sound in place, working with automatic dialogue replacement (ADR), analyzing and fixing common audio problems like clicks and pops, and creating stereo and surround sound design.
Soundtrack Pro features two types of projects: audio file projects and multitrack projects. You use audio file projects to edit individual audio files. You can easily share media projects between Final Cut Pro and Soundtrack Pro. When you send a sequence from Final Cut Pro, your audio files and a compiled video file arrive in a Soundtrack Pro multitrack project.
Soundtrack Pro can be found in Macintosh HD > Applications > Sountrack Pro.
