Patent ID: 8243969

Claim:
A method of generating a Head-Related Transfer Function parameter representing a Head-Related Transfer Function, the method comprising the acts of: splitting by a splitting unit a first frequency-domain signal representing a first Head-Related impulse response signal into at least two sub-bands of the first Head-Related impulse response signal; generating a first parameter of at least one of the two sub-bands of the first Head-Related impulse response signal based on an average root mean square value of the two sub-bands of the first Head-Related impulse response signal; splitting a second frequency-domain signal representing a second Head-Related impulse response signal into at least two sub-bands of the second Head-Related impulse response signal; generating a second parameter of at least one of the two sub-bands of the second Head-Related impulse response signal based on an average root mean square value of the two sub-bands of the second Head-Related impulse response signal; and generating a third parameter representing a phase angle between the first frequency-domain signal and the second frequency-domain signal per sub-band; and generating the Head-Related Transfer Function parameter representing the Head-Related Transfer Function by the first parameter, the second first parameter, and the third parameter.
