Soundtrack Pro

Soundtrack Pro is an audio editor developed by Apple and included as part of the Final Cut Studio suite.

History
The software originated as Soundtrack, targeted towards the editing and assembling of pre-existing audio tracks. It was not a full (DAW) and lacked the MIDI capabilities of GarageBand and Logic. However, it featured the ability to edit to a reference movie with more precise control. Soundtrack 1.5 was included with Final Cut Express HD along with over 4,000 royalty-free instrument loops and sound effects.

The Pro version, which was bundled with Final Cut Studio and Logic Studio, included over 6,000 sound effects, music beds, and music loops, with over 1,000 of them in.

Discontinuation
Soundtrack Pro was discontinued as some of its features were migrated into Final Cut Pro X and Logic Pro X. It no longer functions in macOS High Sierra (10.13) and later.
