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 of inserting an audio watermark is provided to perform a WT(Wavelet Transform) while inserting a watermark, and to detect the watermark without original audio data, thereby inserting the watermark in real time and improving security. CONSTITUTION: A watermark generator(10) generates a watermark signal, and band-spreads the watermark signal by using a PN(Pseudo Noise) signal.

A modulator(20) modulates the band-spread watermark signal by using a predetermined frequency, and controls a gain of the modulated watermark signal by using the entropy. An IWT(Inverse Wavelet Transform) unit(40) inserts the gain-controlled watermark signal into the low frequency band, and performs an IWT process for the watermark signal of the low frequency band and an audio signal of the high frequency band, then outputs an audio signal inserted with an watermark.

Abstract: PURPOSE: An apparatus for eliminating computer noise by adaptive filtering is provided to eliminate noise by installing two additional mikes in a computer main unit and a monitor respectively and introducing an adaptive filtering technique. CONSTITUTION: The apparatus for eliminating computer noise by adaptive filtering is comprised of a mike(11), an adaptive filter(21), a subtraction part(22), and a mike(12). The mike(11) collects noise signals from a computer. The adaptive filter(21) optimizes the noise signals collected from the mike(11) so that they can be approximated to the audio signals a user listens to actually. The subtraction part(22) cancels noise by receiving the signals approximated to the audio signals, executing phase inversion for them, outputting the phase-inverted signals through a speaker(13), and generating a noise-cancelled area. The mike(12) collects the error signals generated through the speaker(13) and feeds them back so as to adjust the coefficient of the adaptive filter(21).
