Transform domain adaptive audio equalizer for active contorl of sound field

摘要

We have reported the osund recrodign and reporduction systme using adaptive FIR filters.Recent work has demonstrated tha tmulti-channel inverse filter may be designed which enable substantial improvements tob emade in the kcharcteisitics of multi-channel sound reporduction system.The approach taken in our work is to use the Mutliple Error LMS (ME-LMS) algorthm to adaptively design a matrix of FIR inverse filters which oeprates on multi-channel recroding system.
