A moving-picture reproducing system has a flat panel display, a flat panel speaker group provided at the front thereof, and low-audio speakers. A video reproducing device reproduces a video from a moving-picture file and displays the same on the flat panel display. An acoustic sound reproducing device reproduces an acoustic sound and allows the flat panel speaker group and the low-audio speakers to output the same. When acoustic data reproduced from the moving-picture file by the acoustic sound reproducing device are synthesized, the synthesized data is separated into a high-frequency audio range and a low-frequency audio range by a filter. The acoustic sound of the high-frequency audio range is played back by the flat panel speaker group, and the acoustic sound of the low-frequency audio range is played back by the low-audio speakers. A sound source position reproducing device sets temporal and spatial thresholds to designate a speaker to be reproduced with a change of a speaker and performs reproduction free of uncomfortable feeling.
