To allow a user to easily learn how to operate the title device by realizing sound image movement, which has been realized through provision of two dimensional or three dimensional information to a control section, by means of providing linear information to a control means so as to relieve the load of the user.
A worker operates an operating knob of an entry fader to trace points of a sound image moving path in a linear motion (one stroke writing) while viewing a sound image moving path menu displayed on a displaying section 5 so as to provide a signal to a control section 2. The control section 2 generates sound image position control information on the basis of a signal from an operation section 4 and supplies the information to a sound image movement processing section 1, which moves a position of a sound image in a sound field on the basis of the sound image position control information so as to apply mixing control to a moving object sound source A thereby providing an output to a plurality of speakers #1,#2,..., #k,...-, #n.
