Iterative Algorithms for Multichannel Equalization in Sound Reproduction Systems
Mathieu Guillaumé, Yves Grenier, Golden G. Richard · 2006
A fast iterative algorithm, with computation based on the fast Fourier transform (FFT), is presented. It can be used to control a sound field at several control points with a loudspeaker array from multiple reference signals. It designs an equalizer able to invert long FIR filters and which achieves better performance than traditional FFT-based deconvolution methods with an equal number of coefficients in the inverse filters.
