An NSArray of NSNumbers that specify the volumes of audio channels sent through the connection.
The values are between 0.0 and 1.0 for normal volume, or greater than 1.0 for boosting the audio gain. This attribute determines the individual volumes of audio channels sent through the connection. Applications that need to set the master volume of all channels can set the QTCaptureConnectionAudioMasterVolumeAttribute attribute. This string value can be used in key paths for key-value coding, key-value observing, and bindings.
