(1). the playback time cannot exceed 30 seconds
(2) the data must be in PCM or IMA4 stream format.
(3). It must be packaged into one of the following three formats: Core Audio Format (. caf), Waveform audio (.wav), or Audio Interchange File (. aiff)
Sound files must be placed under the Local folder of the device. Use the AudioServicesCreateSystemSoundID method to register this sound file.
