-The <guilabel>Show Audio</guilabel> button will instruct DCP-o-matic
-to examine the audio in your content and plot a graph of its level
-over time. This can be useful for getting a rough idea of how loud
-the sound will be in the cinema auditorium. A typical plot is shown
-in <xref linkend="fig-audio-plot"/>

-The plot gives the audio level (vertical axis, in dB) with time
-(horizontal axis). 0dB represents full scale, so if there is anything
-near this you are in danger of clipping the projector's audio outputs.

-There are two plot types: the peak level and the RMS, which can be
-shown or hidden using the check-boxes on the right hand side of the
-window.

-The channel check-boxes will show or hide the plot(s) for
-the corresponding channels in the DCP.

-The smoothing slider applies a variable degree of temporal smoothing
-to the plots, which can make them easier to read in some cases.

-Obviously the audio plot is no substitute for listening in an
-auditorium, but it can be useful to get levels in the right rough area.
