Classification: CPC G  H | IPC H

Claim 0:
1. An audio signal processing method comprising:
detecting a position, in a sound space, of a sound source that generates an audio signal, the sound space being divisible into a plurality of areas;
generating an initial reflected sound control signal by convolving (i) an impulse response of an initial reflected sound linked to a first area corresponding to the detected position of the sound source to (ii) the audio signal of the sound source without (iii) convolving an impulse response of an initial reflected sound linked to any of the plurality of areas of the sound space other than the first area of the sound space corresponding to the detected position of the sound source to (ii) the audio signal of the sound source; and
setting a representative point in each of the plurality of areas in the sound space,
wherein the first area includes a representative point having a shortest distance between the representative point and the detected position of the sound source.
