Digital Signal Processing System to Improve the Sound Quality of a Car Cabin 890258

A digital signal processing system has been developed in order to investigate algorithms for improving sound quality of car audio systems. This system, with external program memories, is able to implement different algorithms by simply changing its programs. Functions of sound field compensation and sound creation are realized by this system. As a result of examination of the system, it was confirmed that our phase compensation method is effective for improving frequency characteristics in automobile interiors.
