What is an STAP file?
File created by Soundtrack Pro, an audio production application used for film and videos; supports both multitrack and waveform editing in the same project and can be synchronized to video; includes references to audio clips as well as any editing decisions.
Soundtrack Pro has been replaced by Apple's newer Final Cut Pro X software.
NOTE: STAP files are forward compatible but not backward compatible with incremental versions of Soundtrack Pro.
