Instance Property

isMeteringEnabled

A Boolean value that specifies the audio-level metering on/off state for the audio player.

Declaration

var isMeteringEnabled: Bool { get set }

Discussion

The default value for the meteringEnabled property is off (Boolean false). Before using metering for an audio player, you need to enable it by setting this property to true. If player is an audio player instance variable of your controller class, you enable metering as shown here:

[self.player setMeteringEnabled: YES];
