## Discussion

If <doc://com.apple.documentation/documentation/Swift/true>, your application can read the [`outputMeterLevel`](/documentation/GameKit/GKVoiceChatService/outputMeterLevel) property to monitor sound level of remote participants. If <doc://com.apple.documentation/documentation/Swift/false>, the value of the [`outputMeterLevel`](/documentation/GameKit/GKVoiceChatService/outputMeterLevel) property is undefined. Default is <doc://com.apple.documentation/documentation/Swift/false>. When your application doesn’t need to monitor remote participants, it should set this property to <doc://com.apple.documentation/documentation/Swift/false> to improve performance.
