ABSTRACT:
Audio reproducing apparatus reproducing an audio signal corresponding to a picture which localizes a sound image in a direction corresponding to the picture by processing an audio signal in a real-time fashion is supplied with an audio signal from a general-purpose signal source such as a laser disc a digital vibratory gyroscope detects a rotational angle of a listener's head. In response to the detected rotational angle, the audio reproducing apparatus subjects the audio signal to a predetermined signal processing in a real-time fashion. Thus, a sound image is localized in the direction corresponding to the picture projected on a screen from a projector.
