Abstract
The basic audio quality of 5.1 multichannel audio reproduction was evaluated subjectively under different technical conditions. The resulting database of subjective responses was used to develop a multichannel audio quality expert system. There are three aims of this development: 1) to predict audio quality as a function of individual channel bandwidth; 2) to predict audio quality as a function of selected down-mix algorithms; and 3) to find the optimum band-limitation algorithm or down-mix algorithm for a given total transmission bandwidth of a multichannel audio signal. Results indicate a close correspondence between predicted and actual quality ratings. It is intended that the final version of the quality expert system will be suitable as a decision-making aid for broadcasters and codec designers.
