摘要
1. The art that the invention defined in the claims ; will present invention relates to a spatial impulse response control device for controlling the sense of space and distance of the stereo sound. ; 2. SUMMARY OF THE INVENTION The attempt to resolve ; The present invention is by controlling the direct sound and early reflections envelope positioning during the reference period of the source of the impulse response, and to control the spatial distance of the stereo, spatial impulse Its purpose is to provide a response that controls. ; 3. Solution subject matter of the invention ; This invention provides a control device for controlling the distance the impulse response of the sound source by controlling the impulse response, the impulse response the direct sound, early reflection period and a late reverberation interval analysis means for dividing the impulse response; Early reflection envelope control means for updating the envelope of the direct sound and early reflections interval outputted from the impulse response analysis means, and outputs the impulse response of the direct sound and early reflections update interval; Synthesizing means for synthesizing an impulse response that is the direct sound and the updated impulse response of the impulse response and the late reverberation period of the early reflection period; And the impulse response comprises means for convolving the filter input from the stereo composite impulse response with the sound source output from the combining unit (convolution) filtering to. ; 4. An important use of the invention ; The present invention is being used for virtual surround sound environment system.
