PROBLEM TO BE SOLVED: To use an impulse response measured in a real space so as to calculate a sound waveform in more detail with a calculation amount smaller than that of a conventional method. SOLUTION: The sound processing apparatus is provided with a space configuration data storage section 12 for storing data with respect to a configuration of a virtual space and with an impulse response segment data storage section 14 stored with segment data of an impulse response of a sound wave actually measured in a real space equivalent to the virtual space, an amplitude/delay calculation section 13 calculates respective amplitude/delay amounts for a direct response and a reflection response on the basis of the space configuration data, an impulse response composite section 15 generates a composite impulse response on the basis of the amplitude delay data produced by the amplitude/delay calculation section 13 and a convolution section 16 convolutes the composite impulse response to sound source sound data. |
