Abstract

A fast iterative algorithm, with computation based on the fast Fourier transform (FFT), is presented. It can be used to control a soundfield 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 traditionnal FFT-based deconvolution methods with an equal number of coefficients in the inverse filters.
