A novel dual-band equalizer design for loudspeaker systems

Abstract

Many equalization methods based on DSP technology have been proposed during the past decade. However, nearly all the methods demand low-frequency components to be processed separately because of deficient resolution. A dual-band equalization method for loudspeaker systems is presented in this paper. In this method, the conventional equalization based on deconvolution of the system response and a recently introduced method based on warped filter design are combined, to achieve a refined performance in the whole audio frequency region with lower order filter. Computer simulations are given to demonstrate the effectiveness.
