+  \section{Quality}
+    Choose the quality here (0 to 7). Default is 5, best quality is 7,
+    smallest file size is 0. This setting effects how much your sound
+    sample will be compressed. Higher quality settings result in larger
+    MP3 files.
+    
+    The quality setting is just a way of selecting an average bit rate,
+    or number of  bits per second, for a recording.  When  this setting
+    is lowered, recordings are compressed more (meaning worse sound quality),
+    and the average bitrate changes as follows.
+  
+  \begin{table}[h!]
+    \begin{center}
+      \begin{tabularx}{0.75\textwidth}{lX}\toprule
+        \emph{Frequency} & \emph{Bitrate} (Kbit/s) -- quality 0$\rightarrow$7 \\\midrule
+        44100Hz stereo   & 75, 80, 90, 100, 120, 140, 160, 170 \\
+        22050Hz stereo   & 39, 41, 45, 50,  60,  80,  110, 130 \\
+        44100Hz mono     & 65, 68, 73, 80,  90,  105, 125, 140 \\
+        22050Hz mono     & 35, 38, 40, 45,  50,  60,  75,  90 \\\bottomrule

+\opt{SWCODEC}{
+  \section{Format}
+    Choose which format to save your recording in. The available choices are
+    the two uncompressed formats \setting{PCM Wave} and \setting{AIFF}, the
+    losslessly compressed \setting{WavPack} and the lossy
+    \setting{MPEG Layer 3}.
+
+  \section{Encoder Settings}
+    This sets the bitrate when using the \setting{MPEG Layer 3} format. And has
+    no settings for the other formats.
+}
+
+  \section{Frequency}
+    Choose the recording frequency (sample rate).
+    \opt{MASCODEC}{48kHz, 44.1kHz, 32kHz, 24kHz, 22.05kHz, 16kHz}
+    \opt{h1xx,h300}{44.1kHz, 22.05kHz and 11.025kHz}
+    \opt{x5}{88.2kHz, 44.1kHz, 22.05kHz and 11.025kHz}
+    are available. Higher sample rates use up more disk space, but give better
+    sound quality.
+    \opt{SWCODEC}{\note{The 11.025kHz setting is not available when using%
+      \setting{MPEG Layer 3} format.}
+    }%
+    \opt{MASCODEC}{
+      The frequency setting also determines which version of the MPEG standard
+      the sound is recorded using:\\
+      MPEG v1 for 48, 44.1 and 32\\
+      MPEG v2 for 24, 22.05 and 16\\
+    }
+    \opt{recorder,recorderv2fm,h1xx}
+      {\note{You cannot change the sample rate for digital recordings.}
+    }  
+
+\section{Source}
+  Choose the source of the recording. This can be
+  \opt{recorder,recorderv2fm,h1xx}{\setting{SPDIF (digital)},}%
+  \setting{Mic} or \setting{Line In}.
+  \opt{CONFIG_TUNER}{For recording from the radio see \reference{ref:FMradio}.}
+
+\section{Channels}
+  This allows you to select mono or stereo recording. Please note that
+  for mono recording, only the left channel is recorded. Mono recordings
+  are usually somewhat smaller than stereo.
+
+\opt{MASCODEC}{
+  \section{Independent Frames}
+    The independent frames option tells the \dap{} to encode with the bit
+    reservoir disabled, so the frames are independent of each other. This
+    makes a file easier to edit.
+}
+      
+\section{File Split Options}
+  This sub menu contains options for file splitting, which can be used to split
+  up long recordings into manageable pieces. The splits are seamless (frame
+  accurate), no audio is lost at the split point. The break between recordings
+  is only the time required to stop and restart the recording, on the order of
+  2 -- 4 seconds.
+  \begin{description}
+    \item[Split Measure:]
+      This option controls wether to split the recording when the
+      \setting{Split Filesize} is reached or when the
+      \setting{Split Time} has elapsed.
+
+    \item[What to do when Splitting:]
+      This controls what will happend when the splitting condition is
+      fullfilled the two available options here are
+      \setting{Start a new file} or \setting{Stop recording}.
+
+    \item[Split Time:]
+      Set the time to record between each split, if time is used as
+      \setting{Split Measure}.\\
+      Options (hours:minutes between splits): Off, 00:05, 00:10, 00:15, 00:30,
+      1:00, 1:14 (74 minute  CD), 1:20 (80 minute CD), 2:00, 4:00, 8:00, 10:00,
+      12:00, 18:00, 24:00.
+
+    \item[Split Filesize:]
+      Set the filesize to record between each split, if filesize is used as
+      \setting{Split Measure}.
+
+  \end{description}
+
+\section{Prerecord Time}
+    This setting buffers a small amount of audio so that when the record button
+    is pressed, the recording will begin from that number of seconds earlier.
+    This is useful for ensuring that a recording begins before a cue that is
+    being waited for.
+
+\section{Directory}
+    Allows changing the location where the recorded files are saved. The
+    default location is \fname{/recordings}. If set to
+    \setting{Current Directory} the recorded files will be saved in the
+    directory where the \setting{File Browser} was left.
+
+\nopt{ondio}{
+  \section{Clipping Light}
+    Causes the backlight to flash on when clipping has been detected.\\
+    Options: \setting{Off}, \setting{Main unit only},
+    \setting{Main and remote unit}, \setting{Remote unit only}.

+    \fixme{Add description of triggered recording.}

+  \section{Automatic Gain Control}
+    The \setting{Automatic Gain Control} has five different presets for
+    automatically controlling the gain while recording.
+    \begin{description}
+      \item[Safety (clip):]
+        This preset will lower the gain when the levels get too high (-1dB)
+        and will never increase gain.
+        
+      \item[Live (slow):]
+        This preset is designed to be used for recording of live shows and has
+        quite large headroom for loud parts. It heads for a nominal target peak
+        level of -9dB and will slowly increase or decrease gain to reach it.
+        
+      \item[DJ-Set (slow):]
+        This preset heads for a nominal target peak level of -5dB and will
+        slowly increase or decrease gain to reach it.
+        
+      \item[Medium:]
+        This preset heads for a nominal target peak level of -6dB and will
+        increase or decrease gain to reach it.
+
+      \item[Voice (fast):]
+        This preset is designed to be used for voice recording and heads for a
+        nominal target peak level of -7dB and will quickly increase or
+        decrease gain to reach it.
+    \end{description}
+
+  \section{AGC clip time}
+    This setting controls how long the level is too loud or soft before the
+    \setting{Automatic Gain Control} kicks in.
