You can install Audio Units plug-ins from manufacturers other than Apple to process audio in Logic Pro, GarageBand, and Final Cut Pro. When installed, Audio Units plug-ins appear as individual components in the Library folders on your Mac:
AU or Audio Units are software plug-ins developed for the macOS and iOS operating systems. Like VST plug-ins, they may either generate sounds, as in the case of instrument plug-ins, or process them, as in the case of effects plug-ins. AU plug-ins are system-level plug-ins that utilize the Core Audio system in Apple operating systems. The vst effect is meant to combine old styles of pitch shifting with the quality you expect from modern plug-ins. The result is this pitch pedal simulation that has most of what is great about guitar harmonizer pedals, and still preserves the signal's integrity.
