-//      Effect control interface
-/////////////////////////////////////////////////
-
-// The effect control interface is exposed by each effect engine implementation. It consists of
-// a set of functions controlling the configuration, activation and process of the engine.
-// The functions are grouped in a structure of type effect_interface_s:
-//    struct effect_interface_s {
-//        effect_process_t process;
-//        effect_command_t command;
-//    };
-
-
-// effect_interface_t: Effect control interface handle.
-// The effect_interface_t serves two purposes regarding the implementation of the effect engine:
-// - 1 it is the address of a pointer to an effect_interface_s structure where the functions
-// of the effect control API for a particular effect are located.
-// - 2 it is the address of the context of a particular effect instance.
-// A typical implementation in the effect library would define a structure as follows:
-// struct effect_module_s {
-//        const struct effect_interface_s *itfe;
-//        effect_config_t config;
-//        effect_context_t context;
-// }
-// The implementation of EffectCreate() function would then allocate a structure of this
-// type and return its address as effect_interface_t
-typedef struct effect_interface_s **effect_interface_t;
-
-
-// Effect API version 1.0
-#define EFFECT_API_VERSION 0x0100 // Format 0xMMmm MM: Major version, mm: minor version

-// - When used for effect type and the engine is implementing and effect corresponding to a standard
-// OpenSL ES interface, this ID must be the one defined in OpenSLES_IID.h for that interface.
-// - When used as uuid, it should be a unique UUID for this particular implementation.

-//    Function:       process
-//
-//    Description:    Effect process function. Takes input samples as specified
-//          (count and location) in input buffer descriptor and output processed
-//          samples as specified in output buffer descriptor. If the buffer descriptor
-//          is not specified the function must use either the buffer or the
-//          buffer provider function installed by the EFFECT_CMD_CONFIGURE command.
-//          The effect framework will call the process() function after the EFFECT_CMD_ENABLE
-//          command is received and until the EFFECT_CMD_DISABLE is received. When the engine
-//          receives the EFFECT_CMD_DISABLE command it should turn off the effect gracefully
-//          and when done indicate that it is OK to stop calling the process() function by
-//          returning the -ENODATA status.
-//
-//    NOTE: the process() function implementation should be "real-time safe" that is
-//      it should not perform blocking calls: malloc/free, sleep, read/write/open/close,
