meter~ Signal level meter meter~ is a simple signal level meter that can be attached to any signal whose level is between -1 and 1. Other signals should be scaled first. Each "LED" on the meter represents a change of 3dB from the previous step, by default. The red "over" LED comes on if the signal is greater than or equal to 1, and lasts for about a second. You can change the redrawing interval with the interval message. Resizing the meter gives its vertical or horizontal orientation, depending on whether its height is greater than its width or vice versa. meter~ outputs the peak signal value received every redrawing interval. Additional appearance settings, such as number of LEDs, and their colors can be set using the inspector (by chooseing "Get Info..." in the object menu).
