PURPOSE:To provide a method capable of securing the continuity of the moving feeling of a sound source even though a speaker interval is wide and the moving speed of the sound source is slow by controlling the total sum of acoustic energy or sound pressure in a listener position at a constant. CONSTITUTION:A controller 3 considers the arrangement and the number of plural speakers 5, calculates gain for original sound source signals so that the total sum of the sound pressure or the acoustic energy emitted from the respective speakers 5 in the listener position become constant or similar thereto based on the signals of a position information signal source 2 and convolutes it to the signals of an original acoustic signals source 1 to be inputted. Then, acoustic signals to which position information is convoluted are delivered to respective acoustic channels 4 and reproduced by the speakers 5. By the constitution, the method for imparting the moving feeling of the sound source provided with a function capable of adjusting the envelope of emitted sound waveforms from the speakers so as to impart the continuous moving feeling to a listener even though the speaker interval is wider and the moving speed is slower can be obtained. |
