Abstract:
1. An apparatus for generating a reverberation sound from an input sound with use of an impulse response based on an instruction, the apparatus comprising: a first storage section that stores first impulse response data representative of a first impulse response; a second storage section that stores second impulse response data representative of a second impulse response which is different from the first impulse response represented by the first impulse response data; a new data creating section that operates based on the first impulse response data and the second impulse response data for creating new impulse response data representative of a new impulse response in accordance with the instruction; and a reverberation sound generating section that generates reverberation sound data representative of the reverberation sound by filtering input sound data representative of the input sound with use of the new impulse response data, such that the generated reverberation sound is featured by the new impulse response, wherein the new data creating section divides the first impulse response data into a sequence of first blocks along a time axis, divides the second impulse response data into a sequence of second blocks along the time axis, and creates a sequence of blocks of the new impulse response data arranged along the time axis in correspondence to the sequence of the first blocks of the first impulse response data and the sequence of the second blocks of the second impulse response data.
