//				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	//
//				respectively.												//
