| description | PURPOSE: A method for synthesizing artificial indoor impulsive response function is provided to obtain natural reverberation effect by an artificial indoor impulsive response function having efficient reverberation density. CONSTITUTION: A method for synthesizing artificial indoor impulsive response function includes a first step(200) of synthesizing an artificial indoor impulsive response function by an artificial indoor impulsive response function synthesizing module, performing a convolution of the artificial indoor impulsive response function to an original sound to increase a reverberation density by hours without periodicity, and catching an arrangement(h£len|:len is length of arrangement) to initialize the arrangement value(h£1|=1,h£n|=1 (n is not 1)), a second step(201) of determining parameters(nd: integer between 1 and len, g1 and g2: real number of which absolute value is below 0.5) for synthesizing the artificial indoor impulsive response function, a third step(202) of generating a random integer(d) between 1 and 2nd, a fourth step(203) of adding g1h£n| to n+dth arrangement value h£n+d| and g2h£n| to n+2dth arrangement value h£n+2d|, and repeating the above steps by increasing n by 1 until n exceeds the len to obtain an artificial indoor impulsive response function arrangement h£n|. |
