<P>PROBLEM TO BE SOLVED: To provide an audio signal processing device, e.g. a digital mixer, in which a user can define the relationship of volume level adjustment and sound quality adjustment freely. <P>SOLUTION: A set of a group of parameter values used for sound quality adjustment constitutes a "pattern", and a plurality of patterns A, B are stored in a memory. The weight characteristics WA, WB of each pattern A, B are set for the fader level, and the parameter values are cross-faded. When the center frequency of pattern B is (100 Hz), and the center frequency of pattern A is (200 Hz), for example, and the fader level is increased gradually in the cross-fade section, the center frequency increases gradually from 100 Hz toward 200 Hz. <P>COPYRIGHT: (C)2013,JPO&INPIT |
