Title:
LOCALIZATION SOUND IMAGE GENERATOR
Document Type and Number:
Japanese Patent JP3197077
Kind Code:
B2
Abstract:
PURPOSE: To obtain a localization sound image with high quality and inexpensive and small scale of circuit configuration.
CONSTITUTION: Seven series of waveform data read from a waveform memory 1' are fed to a demultiplexer 3, from which the data are respectively given to multipliers 4a-4g. The supplied 7 series of waveform data are multiplied with multiplication coefficients GA-GG in response to a vertical angle θ supplied from a controller 2 at the multipliers 4a-4g, the results are added by an adder 5 and one waveform data are obtained. Then a reverberation tone is generated in a l' in response to a distance D from the added waveform data at multipliers 6a, 6b, and a delay time difference and an amplitude difference are given to an R-channel component and an L-channel component in response to a horizontal angle ψ at multipliers 8a, 8b.
