* @brief Stonestreet One Bluetooth Stack Advanced Audio Distribution
* Profile Type Definitions and Constants.
*
* @section A2DP Programming Interface
* The Advanced Audio Distribution Profile programming interface defines the protocols
* and procedures to be used to implement A2DP capabilities. Because the
* Advanced Audio Distribution Profile is so heavily dependent on the
* Generic Audio/Video Distribution (GAVD) Profile which uses the
* Audio/Video Distribution Protocol (AVDTP), there are no additional functions
* required to implement this profile. The application programmer can simply
* use the GAVD Profile API in conjunction with the constants and MACROs that
* are defined in the Advanced Audio Distribution Profile API header file to
* implement the Advanced Audio Distribution Profile. It should be noted that
* most of the A2DP Specification deals with the implementation of the
* Subband CODEC (SBC). Stonestreet One provides a Subband CODEC library
* that can be used by application developers to manager
* SBC stream encoding and decoding. The programmer should consult
* the GAVD and SBC documentation, in addition to the core Bluetopia documentation,
* when implementing Bluetooth applications that conform to
* the Advanced Audio Distribution Profile Specification.
*
* The necessary SS1 Audio profile and Sub-System Headers can be included in an application
* as below.
