In the last years, automotive audio applications have been receiving increasing interest: due to traffic congestion and growing distance from home to workplace, car is nowadays the most used audio listening environment. In this context, audio equalization is a relevant and challenging issue because of the car cockpit is far from being an ideal listening environment. In this paper, a valid approach comprising fixed and adaptive equalization (implemented on a PC platform) is presented, offering a custom graphical user interface the user can interact with. To validate the proposed approach, the system has been installed inside a real car with professional audio equipment. Simulated and real in-car tests have been performed and their results will be reported.
