\subsection{VU meter}
\screenshot{plugins/images/ss-vumeter}{VU-Meter}{}

This is a VU meter, which displays the volume of the left and right
audio channels. There are 3 types of meter selectable.  The analogue
meter is a classic needle style.  The digital meter is modelled after
LED volume displays, and the mini{}-meter option allows for the display
of small meters in addition to the main display (as above).  From the
settings menu the decay time for the meter (its memory), the meter type
and the meter scale can be changed.
