Instance Property

calibratedLatency

The user-calibrated latency for the current screen.

Declaration

@property(nonatomic, readonly) CFTimeInterval calibratedLatency;

Discussion

Use this property when you need to manually synchronize video playback with custom audio. For example, you might correlate this value with the latency property of a Core Audio unit when writing custom video-playback software. The value of this property is 0 until the user explicitly calibrates their display.
