Abstract: PURPOSE: A method for reproducing a stereophonic sound is provided to offer the effect of 3-dimensional sound image fixing to a listener by correcting a standard head transfer function according to a size of the listener's head. CONSTITUTION: An azimuth angle and an altitude angle based on real left or right ear are calculated from a standard head related transfer function database(11) measured by using a standard head sized dummy head(12). An index of the standard head related transfer function database(11) is corrected on the basis of the azimuth angle and the altitude angle(13). A position in a 3-dimensional space is inputted. An azimuth angle and an altitude angle are calculated on the basis of left or right ear of a listener from the position inputted(15). The azimuth angle and the altitude angle calculated on the basis of left or right ear of the listener are indexed. A head related transfer function corrected(16,17) is obtained from the standard head related transfer function database(11) corrected. An input mono signal is convoluted with the head related transfer function obtained(18,19). After that, an inverse proportion factor is multiplied according to the distance. Therefore, a stereophonic sound is reproduced.

Abstract: PURPOSE: A device for creating reverberations without tone variations is provided to produce natural reverberation sounds by designing a specific frequency's characteristics to be similar to an ordinary indoor reverberation characteristics and shortening the reverberation time for high pitch sounds. CONSTITUTION: A device for creating reverberations without tone variations is composed of reception, output, and synthesization. An initial reverberation sound generator(110) receives the sounds, which do not possess reverberations, creates an initial reverberation sound, adjusts the spacial sensation, and outputs the sound. A comb filter(120) receives a sound source that lacks reverberation, creates and outputs reverberation signals. A low-threshold passage all-pass filter(130) increases the comb filter generated reverberation sound's density and outputs the sound. The synthesizer(100) synthesizes the sound that has been output by the initial reverberation sound generator and the low-threshold passage all-pass filter's output signal. The synthesizer creates and outputs a reverberation signal that lacks tone variations.
