- \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

- \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.

- \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.

- \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{Clear Recording Directory}
- Resets the location where the recorded files are saved to the root of your
- \daps{} drive.
-
-\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}.

- \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.
