# com.apple.developer.coremotion.head-pose

An entitlement that enables someone’s head movement to determine the orientation of spatialized sound output.

## Discussion

This entitlement changes the orientation of spatial audio output to match the person’s head pose via compatible AirPods for the following APIs:

- <doc://com.apple.documentation/documentation/AVFAudio/AVAudioEnvironmentNode>, when you set the <doc://com.apple.documentation/documentation/AVFAudio/AVAudioEnvironmentNode/isListenerHeadTrackingEnabled> property to `true`
- <doc://com.apple.documentation/documentation/AudioToolbox> (see <doc://com.apple.documentation/documentation/AudioToolbox/1390073-auspatialmixer-parameters>), when you set the <doc://com.apple.documentation/documentation/AudioToolbox/kAudioUnitProperty_SpatialMixerEnableHeadTracking> property to `true`
- <doc://com.apple.documentation/documentation/PHASE/PHASEListener>, when you set the new <doc://com.apple.documentation/documentation/PHASE/PHASEListener/automaticHeadTrackingFlags> property to orientation

Add this entitlement to your app by enabling the Head Pose capability in Xcode.
