Abstract: A stereophonic sound reproduction system is aimed at synthesizing at a multiplicity of points (L) in the listening space. An auditory effect obtaining at corresponding points (K) in the recording space, to compensate for crosstalk (C21, C12) between the loudspeakers, the acoustic response of the listening space, and imperfections in the frequency response of the speaker channels. Each speaker channel incorporates a digital filter (H) with the characteristics of which are adjusted in response to measurements of the reproduced field. The digital filters are provided by an inverse filter matrix (H) of which the matrix elements (Hij) are determined by a least squares technique, applied so as to minimize the sum of the squared errors resulting from the difference between the actual system impulse response and a desired impulse response. A full bandwidth signal is transmitted by a bypass route for combination with the output signal (9) from the filter, the bypass route including a delay means (F).
