<P>PROBLEM TO BE SOLVED: To facilitate knowing the relation between frequency component characteristics and an adjusting operation causing the frequency component characteristics to be changed. <P>SOLUTION: Both an input signal fed to a means for changing the signal frequency component characteristics on each input/output channel and an output signal from the changing means are taken out about any input/output channel designated by a designating means. The taken input and output signals are analyzed about their frequencies, and the analysis result is monitored to allow a user to compare the input and output signals. This enables the user to easily know the relation between frequency component characteristics of the signals and an adjusting operation causing the change of the frequency component characteristics, and hence to more easily check the degree of influence on mixed signals after mixing process e.g. due to change in the frequency component characteristics of the signals by comparing the input and output signals. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
