Patent ID: 8331575

Claim:
A data processing apparatus for simulating acoustic characteristics of an acoustic space in which a sound emitting point for emitting a sound and a sound receiving point for receiving the sound emitted from the sound emitting point are placed, the data processing apparatus comprising: a sound receiving point orientation specifying portion for specifying the orientation of the sound receiving point in the acoustic space; a sound path calculating portion for calculating a plurality of sound paths along which sounds travel from the sound emitting point to the sound receiving point; a distribution ratio defining portion for defining, on the basis of an entering angle of each of the calculated sound paths which enter the sound receiving point with respect to the orientation of the sound receiving point, distribution ratio of audio signals for at least three or more channels, the distribution ratio being defined for each of the sound paths; and a distributing portion for distributing a plurality of audio signals on the sound paths among the channels in accordance with the defined distribution ratio.
