An acoustic signal processing apparatus includes an acoustic signal input device, a frequency resolution device, a two-dimensional data generating device, a graphics detection device, a sound source candidate information generating device, and a sound source information generating device. The sound source information generating device generates sound source information including at least one of the number of sound sources, the spatial existence range of the sound source, an existence period of the voice, a frequency component configuration of the voice, amplitude information on the voice, and symbolic contents of the voice based on the sound source candidate information and corresponding information which are generated by the sound source candidate information generating device.
