Sound image localization setting apparatus, method and program
First Claim
1. A sound image localization setting apparatus for setting sound image localization for an audio signal processing apparatus which performs processing to localize a sound image of an audio signal, said sound image localization setting apparatus comprising:
- a movement pattern generator that generates a movement pattern indicative of a movement trajectory of a sound-image localized point;
a movement control section that moves the sound-image localized point over time in accordance with the movement pattern generated by said movement pattern generator; and
a stop control section that stops movement, by said movement control section, of the sound-image localized point at a desired point on the movement trajectory, wherein the sound-image localized point on the movement trajectory when the movement of the sound-image localized point has been stopped by said stop control section is set as a sound image localization point.

Abstract
Movement pattern is generated which is indicative of a movement trajectory of a sound-image localized point, and the sound-image localized point is moved over time in accordance with the generated movement pattern. Thus, states set for various sound-image localized points can be automatically presented sequentially, without a user performing particular manual panning operation. By stopping the movement of the sound-image localized point at a desired point on the movement trajectory, the sound-image localized point on the movement trajectory when the movement has been stopped can be set as a sound image localization point. Audio signal, having been subjected to sound image localization control sequentially varied in accordance with the moved sound-image localized point, is audibly generated. Thus, the user listens to the generated audio and gives a movement stop instruction when he or she has auditorily felt that desired optimal sound image localization has been obtained, so that the localized point obtained at that time can be readily set as a sound image localization point.
