Patent ID: 8351623

Claim:
An audio mixing apparatus comprising: a plurality of faders that control tone volume parameters of a plurality of channels respectively in accordance with current positions; a display that displays respective signal levels of the channels as a level meter image; a signal level storing device that stores the respective signal levels of the respective channels; a signal type storing device that stores signal types to be set for the channels, each signal type indicating whether a signal of a channel of the signal type is correlated with that of its neighboring channel to control the channel so that when the signal type of the channel indicates that there is a signal correlation between the channel and its neighboring channel, the fader of the channel and that of the neighboring channel are situated at the same position; and a controller that: generates the level meter image using respective bars of a bar graph indicative of the respective signal levels of the channels stored in the signal level storing device; generates an image indicative of indicators of the channels, respectively, so that the respective indicators correspond to the respective bars of the bar graph indicative of the channels, the indicators being designed so that when the signal type of the channel stored in the signal type storing device indicates that there is the signal correlation between the channel and its neighboring channel, the indicator of the channel has a connected shape shared with the neighboring channel; and synthesizes the generated images to display the synthesized image on the display.
