A Software Tool for Real Time Modeling and Simulation of Car Audio Systems 2001-01-3236

This paper presents a new software tool that is able to model, store, reproduce and compare car audio systems. The software uses a discrete-time, linear, time-invariant MIMO model, implemented by a matrix of FIR filters. To identify the model parameters a MLS based estimation method is employed while the effects of the acquisition and reconstruction devices (microphones, headphone, etc.) are reduced using an inverse filter adaptively designed. The simulator is able in real time to compare different audio systems, to change seat and select a head pan and tilt within a number of fixed positions. To make the listening experience more effective, a novel visual feedback has been added to the audio simulator, i.e. it is possible to be “virtually seated” in the car seeing the interior from the proper point of view.
