Instance Property


The audio gain to apply to the processed Live Photo.


@property float audioVolume;


Values must be between 0.0 and 1.0, inclusive. A value of 1.0 (the default) leaves the audio content of the Live Photo unchanged. A value of 0.0 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.
