AB  - In order to improve the spatial fidelity of automotive audio systems by means of digital signal processing, the authors investigated means to objectively assess the spatial perception of reproduced stereophonic sound in car cabins. It implied choosing a convenient binaural microphonic system representative of real listening situations and metrics to analyze interaural time differences under 1.5~kHz in those binaural recordings. Frequency-dependent correlation correctly showed the frequencies at which the fidelity was improved and allowed to quantify the improvement. The time-domain correlation seemed to be a good indicator of the apparent source width, but failed at giving the perceived azimuth of the virtual sound source. Therefore that metric must be refined to be used efficiently during audio tunings.
