Signal processing for loudspeaker evaluation and equalization
This paper presents some possibilities of digital signal processing for the loudspeaker measured impulse response. The linear distortion of a loudspeaker can be described using cumulative-decay spectrum (CDS) and energy-time curves (ETC). Some applications are presented. The implications on CDS and ETC of digital crossover alignments are analyzed. We consider a non minimum phase loudspeaker impulse response and the phase distortion is analyzed using digital equalization networks. A two-stage digital equalizer is presented.
