Adaptive Loudspeaker Systems: Correcting for the Acoustic Environment
Loudspeaker designers have long recognized the influence of the acoustic environment on the perceived quality of an audio system. The availability of powerful digital signal processor (DSP) integrated circuits has created interest in the application of adaptive digital filtering techniques to the equalization of loudspeakers in rooms. A review of some recently proposed implementations is followed by a discussion of the issues which must be considered in order to address the problem successfully. Results obtained from an experimental system are presented.
