<P>PROBLEM TO BE SOLVED: To provide a musical tone signal processing apparatus, capable of freely expanding or contracting an acoustic image of a desired musical tone in inputted musical tones. <P>SOLUTION: According to a musical tone signal processing apparatus, when a second reference localization, a first function stipulating expansion of the boundary of one end of a direction range and a second function stipulating expansion of the boundary of another end of the direction range are set by a second setting means, an output direction indicated by localization information of an extraction signal that exists in the direction range in which the conditions have been set in this manner is shifted by an acoustic image scaling means. Thus, the acoustic image within the direction range is expanded or contracted. Therefore, the acoustic image formed by the extraction signal extracted from the set direction range is expanded or contracted by shifting the output direction indicated by localization information for each extraction signal extracted from within the set direction range, thereby freely expanding or contracting each acoustic image indicated by a stereo sound source. <P>COPYRIGHT: (C)2011,JPO&INPIT |
