PROBLEM TO BE SOLVED: To allow the level of an audio signal to be displayed while reflecting the difference of attenuation speed corresponding to the difference in the type of a sound source.SOLUTION: A display controller includes a setting section 11 for variably setting the display delay time of a level meter 13 for the attenuation change in the level of an audio signal, and a control section 12 for controlling the level value to be displayed in the level meter, based on the display delay time set in the setting section 11 and the level of the audio signal. For example, in a memory 22, the display delay time information pre-defining the display delay time suitable to each type indicating the supply source of the audio signal is stored. The setting section 11 sets the display delay time corresponding to the type indicating the supply source of the audio signal of each channel of a mixer 20, based on the display delay time information.SELECTED DRAWING: Figure 1 |
