<P>PROBLEM TO BE SOLVED: To provide a digital signal processor 10 which is provided with a DSP 100 for attenuating received audio data Dau in advance and applying tone control to the attenuated data and which can increase / decrease an output level of the DSP 100 without incurring a sense of incongruity in a listening sense independently of whether or not the DSP 100 carries out the tone control. <P>SOLUTION: The image processor 10 is provided with a digital volume section 105 for increasing / attenuating the output level of the DSP 100 and a coefficient generating section 106 being a component of the digital volume section 105 and the counter of which generates a multiplication coefficient with the output data of the DSP 100 adjusts the number of steps of the counter depending on whether or not the tone control is carried out. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
