Multichannel audio data processing device for automobiles

Abstract

Multichannel Audio Data Processing Device for Motor Vehicles. The invention relates to the field of audio processing for motor vehicles. It allows for phase alignment correction between various frequencies for each row of the vehicle with limited computing power. Unlike the Stage algorithm or manual adjustment of all-pass filters, this solution is based on metrology; phase problems in the car are measured, and correction is performed using a measurement system. Furthermore, this correction can be customized, balanced between the first and second rows, or centered on the first or second row, albeit at the expense of the other row.
