Enumeration Case


So-called factory presets (as opposed to user-configured presets) are ones supplied with an audio unit by the manufacturer. You choose the active preset by setting the kAudioUnitProperty_PresentPreset property.


kAudioUnitProperty_FactoryPresets = 24


A read-only CFArrayRef array of AUPreset structures.

When obtaining a factory preset array from an audio unit with the AudioUnitGetProperty function, you own the reference to the array and are responsible for later releasing it by calling the CFRelease function.
