Fecha de publicación: 27/09/1995 Fuente: Wipo "digitalization" An audio reproducing device such that the memory capacity can be small, the signal processing speed is high, and the reproduction is not affected by sound collecting conditions. This reproducing device is equipped with convolution integrators (5, 7, 9 and 11) which perform convolution integration in real time of a pair of impulse responses digitally recorded in a memory (35) and containing the correction characteristics of a sound source and a headphone used at the time of measuring the impulse responses based on digital signals from a multichannel digital stereo signal source (2) or digital signals obtained by converting analog signals from a multichannel analog stereo signal source (2) by means of an A/D converter (3) and based on the angle of the head of the listener (23) with respect to a reference position.
