Abstract

For the dereverberation of acoustic channels or the rendering of a specific sound field, the inversion of acoustics is a central problem and generally involves multichannel techniques. In this paper, we introduce a subband approach to the adaptive solution of this equalization problem. The presented method generally allows for faster convergence at lower complexity. We also address limitations of the subband technique, potential error sources, and design specifications. Simulations are presented underlining the use of our method.
