Abstract  Abstract

A device which generates a sound source vector has a pulse vector generating unit having N (N>/=1) channels which generates pulse vectors, a storage unit in which M (M>/=1) channels which generate pulse vectors, a storage unit in which M (M>/=1) types of diffusion patterns are stored for each channel, a selection unit which selectively takes out the diffusion patterns corresponding to each N channel from the storage unit, a diffusion unit which performs calculation of superposition of the taken out diffusion patterns and the generated pulse vectors for each channel to generate N diffusion vectors, and a sound source vector generating unit which generates a sound source vector from the generated N diffusion vectors.
