Optimum Equalizer Design for Desktop Loudspeakers

Article Preview

Abstract:

Loudspeaker equalization aims at mitigating the distortions introduced in the process of audio reproduction. Conventional equalization schemes focus mainly on the axial room impulse response, and thus cannot fulfill the requirements of near-filed applications such as desktop loudspeakers. This paper describes a novel equalization scheme, in which the problem is partially solved by taking the binaural perception difference into consideration.
