1. A sound signal processing method comprising:
receiving a sound signal from a real-world sound source;
generating an early reflection sound control signal that reproduces an early reflection sound and a reverberant sound control signal that reproduces a reverberant sound from the sound signal;
generating a direct sound control signal to reproduce a direct sound, by controlling a volume of the sound signal and then distributing the sound signal to output lines according to a distance between the real-world sound source and each of a plurality of speakers so that a sound image of the real-world sound source is localized at a position of the real-world sound source; and
mixing the direct sound control signal, the early reflection sound control signal, and the reverberant sound control signal to generate an output signal.
