//              input samples can be found in the variables iChannel0LeftIn,//
//              iChannel0RightIn, iChannel1LeftIn and iChannel1RightIn      //
//              respectively. The processed data should be stored in        //
//              iChannel0LeftOut, iChannel0RightOut, iChannel1LeftOut,      //
//              iChannel1RightOut, iChannel2LeftOut and iChannel2RightOut   //
