<P>PROBLEM TO BE SOLVED: To perform signal processing on an audio signal to change a sound with a specific one of relationships of feature quantities depending on frequencies between a plurality of channels into a sound with a different relationship. <P>SOLUTION: A signal processing part 100 of a terminal according to an embodiment of the present invention converts audio signals of a plurality of acquired channels into a frequency spectrum, calculates a sound image position corresponding to each frequency, and displays it on a display screen using a coordinate system with coordinate axes of the frequency and the sound image position. A portion of a region in a coordinate system that is specified by a user is set as a specified region. By setting a variation mode for changing a correlationship between a frequency value and a relationship value into a different correlationship, the signal processing part 100 changes a first frequency spectrum of each channel into a second frequency spectrum based on a set variation mode, and converts it into an audio signal to output. <P>COPYRIGHT: (C)2012,JPO&INPIT |
