Use of Digital Inverse Filtering Techniques for Improving Car Audio Systems
This paper describes the theory and an experimental application of digital inverse filtering applied to the correction of the response of sound systems in car compartments. The aim of this correction is not simply to equalize the frequency response of the transducers by a proper implementation of the inverse filters, it is possible to create a "virtual acoustics" system, which makes it possible to move the apparent position of the sound sources. This way, the original sound field inside the car is substituted with a very different one, coming from measurements taken in brilliant concert halls, or even from numerical simulations of non-existing spaces.
