On the Design of a Sparse Adaptive Room Equalizer

Adaptive room equalization is a technique which compensates for the modification of a sound signal caused by the impulse response of the room in which the sound is played. Room impulse responses as well as the impulse response of the equalizer are generally sparse in nature. However, traditional adaptive room equalizers are not designed to make use of this sparseness. In order to utilize the sparse nature of the scenario, this paper proposes a sparse adaptive room equalizer. The proposed scheme has been shown through a simulation study to provide improved room equalization over conventional methods.
