-     * Effect process function. Takes input samples as specified (count and

-     * output buffer. If the buffer descriptor is empty the function must use
-     * either the buffer or the buffer provider callback installed by the
-     * setConfig command.  The effect framework must call the 'process' function
-     * after the 'enable' command is received and until the 'disable' is
-     * received. When the engine receives the '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 INVALID_STATE status.
+     * Set up required transports for passing audio buffers to the effect.
      *
-     * Output audio buffer must contain no more frames than the input audio
-     * buffer. Since the effect may transform input channels into a different
-     * amount of channels, the caller provides the output frame size.
+     * The transport consists of shared memory and a message queue for reporting
+     * effect processing operation status. The shared memory is set up
+     * separately using 'setProcessBuffers' method.

+     * Processing is requested by setting 'REQUEST_PROCESS' or
+     * 'REQUEST_PROCESS_REVERSE' EventFlags associated with the status message
+     * queue. The result of processing may be one of the following:
+     *   OK if there were no errors during processing;
+     *   INVALID_ARGUMENTS if audio buffers are invalid;
+     *   INVALID_STATE if the engine has finished the disable phase;
+     *   NOT_INITIALIZED if the audio buffers were not set;
+     *   NOT_SUPPORTED if the requested processing type is not supported by
