PROBLEM TO BE SOLVED: To provide a sound field effect controller than utilizes information reflecting on a sound source position of a multi-channel audio source signal so as to enable a listener to hear reflected sounds close to an initial reflection sound in an actual acoustic space. SOLUTION: An initial reflection sound generating section 100 receives 4 channel audio source signals SLF, SRF, SLR, SRR that outputted from plurality of speakers so as to allow a listener to hear a sound generated from a prescribed virtual sound source position. This initial reflection sound generating section 100 generates a plurality of channels of initially reflected sound signals ERLF, ERRF, ERLR, ERRR, corresponding to the initial reflection sounds to be heard by the listener, when the virtual sound source sounds into a prescribed sound space from audio source signals of a plurality of channels. The initial reflection sound signals are given to adders 21-24, which provide the signal to original audio source signals. |
