A subband implementation of a multichannel and multiple position adaptive room response equalizer
2021
Abstract This paper deals with a subband implementation of an adaptive multichannel and multiple position room response equalization system capable of improving the listening experience in a real environment. The main focus of the approach is the introduction of a subband identification procedure capable of estimating in real-time the magnitude responses of a system with a great accuracy and a quick convergence. These aspects are very important also for the equalization procedure to obtain a good accuracy and quick development of the equalization filters as function of the environment variations. Several experiments have been performed in a real scenario to test the performance of the algorithm and to show the beneficial effects of the subband identification on the equalization procedure.
