PURPOSE:To move a sound image along a preliminarily determined movement route of the sound image. CONSTITUTION:A DSP 36 inputs signals, which are obtained by digitizing the left input signal of an input terminal 12 and the right input signal of an input terminal 13 by A/D converters 32 and 34, as the input and two-dimensionally moves the sound image based on the two-dimensional control signal from a CPU 46. The CPU 46 corrects data from a track ball 54 by mapping on a line 56, which is displayed on a display device 50 and indicates the preliminarily determined movement route of the acoustic image, so that the sound image is placed on the line 56 even if the track ball 54 doesn't accurately trace the line 56, and this data is supplied to the DSP 36. |
