Abstract
A volume control may be provided with some integrated graphical indication of the presence and/or level of an audio signal that it controls. For example, a slider-type volume control may be provided with a signal meter within the slider itself. A volume control may be provided with a mechanism for showing the non-mute volume control level of a volume when the volume control is muted. For example, a slider-type volume control may display a ghosted slider tab at the level of volume control in effect before muting while at the same time displaying a regular slider tab at a muted level. A user may be able to glance at a volume control and quickly and intuitively understand aspects of the volume control's state such as the level and condition of the signal that is flowing through or blocked by (if muted) the control.
