Patent ID: 8520871

Claim:
A device for processing parameters representing Head-Related Transfer Functions, the device comprising: a splitter configured to split 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, wherein the splitter is further configured to split 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; and a generator configured to generate 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, wherein the generating is further configured to generate 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, wherein the generating is further configured to generate a third parameter representing a phase angle between the first frequency-domain signal and the second frequency-domain signal per sub-band; and wherein the generating is further configured to generate the Head-Related Transfer Function parameter representing the Head-Related Transfer Function by the first parameter, the second first parameter, and the third parameter.
