<para>
<command>rdrender</command><manvolnum>1</manvolnum> can be used to render
an existing Rivendell log as a single audio file, thus enabling playback
of the rendered content independently of Rivendell.
</para>
<para>
Three different types of options can be given to
<command>rdrender</command><manvolnum>1</manvolnum>: Output,
which affect the outputs of the program, Rendering,
which control how a log is virtually "played" and Audio,
which control the format of the resulting audio file. Each group of
options is documented separately below.

<command>rdrender</command><manvolnum>1</manvolnum> makes no attempt to
interpret hard-start time values beyond allowing them to be
used to flag the start and end of rendering. (See the
<option>--first-time</option> and <option>--last-time</option> rendering
options).
</para>
<para>
Due to limitations inherent in the 32 bit Broadcast Wave File format used in
Rivendell's audio store, the maximum length of the rendered log is limited
to appoximately three hours for stereo and six hours for mono when using
the <option>--to-cart</option> option.
