Equalization Method and Implementation of Loudspeaker System Based on Adaptive Pre-filtering Algorithm
MA Dengyon · Audio Engineering · 2014
To improve the frequency response performance of the whole system including the power amplifier and loudspeaker box,the frequency response equalization method and implementation based on adaptive pre-filtering algorithmare presented. Combined the source signal with the feedback signal,the serial pre-filter responses can be calculated in sequence using the adaptive iteration method. The inverse filtering effect can be achieved via the real time system frequency response compensation using the multiple pre-filters.
