   MODULE  : MFW_AUD

   PURPOSE : This module contains the definitions for the Audio Riveria Interface.

    HISTORY:
	Mar 31, 2006   ER: OMAPS00067709  x0pleela
	Description: Voice Buffering implementation on C+ for PTT via PCM API
	Solution: Added new field play_stopped to voice buffering data to keep a check before
			calling play stop during end call

	Mar 15, 2006   ER: OMAPS00067709  x0pleela
	Description: Voice Buffering implementation on C+ for PTT via PCM API
	Solution: Defined new macro for PTT number length
			Defined new Enumeration "T_VOICEMEMO" (which defines different types of voice memo)
					and "T_VOICE_BUFFERING_STATUS" (Voice buffering status)
			Defined new structure "T_voice_buffering" to handle diferent scenarios during voice buffering
			Added prototypes of functions set_voice_memo_type, get_voice_memo_type,
					set_voice_buffering_rec_stop_reason.
