In-Car Audio

These are the main topics addressed within this main research field:

  • Advanced Car Information System: In the last decade Car infotainment (i.e. the combination of information with entertainment features) systems have attracted many efforts by industrial research because car market is sensible to the introduction of innovative services for drivers and passengers. The need for an Advanced Car Infotainment System (ACIS) has been recently emerging, able to handle issues left open by CIS systems already on the market, and to overcome their limitations. Due to traffic congestion and growing distance from home to workplace, people spend more and more time in car, that hence becomes an appealing place to do many common activities such as listening to music and news, phone calling and doing many typical office tasks. Narrowing our focus to audio, the key role of the CIS is that it lets the driver concentrate on the road and at the same time it manages many different processing functions such as high quality music playback, hands-free communication, voice commands, speaker recognition, etc. Moreover, from the signal processing point of view, the wideband nature of the audio signal adds complexity while the requested quality calls for high precision signal processing, making in-car audio processing a very open research and development field. Therefore new architectures are needed to overcome the nowadays limitations. 
  • Professional Audio: Automotive audio system design has recently attracted many efforts by academic and industrial research: by considering the spectral, spatial and temporal characteristics of the vehicle listening enviroment, it is possible to define a complete set of solutions regarding the automotive amplifier scheme, loudspeaker design parameters and placement in order to set the desired level of listening pleasantness.
