The audio gain to apply to the processed Live Photo.
- iOS 10+
- macOS 10.12+
- Mac Catalyst 13.0+
- tvOS 10+
Values must be between
1, inclusive. A value of
1 (the default) leaves the audio content of the Live Photo unchanged. A value of
0 mutes all audio in the output Live Photo.
Setting this property does not process the Live Photo content; instead, it sets the audio gain to be applied when you later process the Live Photo using one of the methods listed in Processing an Editing Context’s Live Photo.
