+ screen}{}
+
+ Entering the \setting{Recording} option in the \setting{Main Menu} brings up
+ a screen in wich you can choose to enter the \setting{Recording Screen} or
+ the \setting{Recording Settings} (see below). The \setting{Recording Screen}
+ shows the time elapsed and the size of the file being recorded. A peak meter
+ is present to allow you set Gain correctly. There is also a volume setting,
+ this will only affect the output level of the \dap\ and does \emph{not}
+ affect the recorded sound.
+ \opt{MASCODEC}{The frequency, channels and quality}
+ \opt{SWCODEC}{The frequency and channels} settings are shown on the last line.
+
+ The controls for this screen are:
+
+ \begin{table}

+ \begin{description}
+ \item[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.

+ \opt{MASCODEC,x5}{
+ \item[Frequency:]
+ Choose the recording frequency (sample rate) -- 48kHz, 44.1kHz, 32kHz and
+ 24kHz, 22.05kHz, 16kHz are available. Higher sample rates use up more disk
+ space, but give better sound quality.
+ This setting determines which frequency range can accurately be reproduced
+ during playback, Lower frequencies produce smaller files.
+ \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\\
+ }
+ }
+ \item[Source:]
+ Choose the source of the recording. This can be
+ \opt{recorder,recorderv2fm,h1xx}{SPDIF (digital),} microphone or line in.
+ \opt{CONFIG_TUNER}{For recording from the radio see page \pageref{ref:FMradio}.}
+
+ % Add h1xx here whenever it supports setting recording frequency.
+ \opt{recorder,recorderv2fm}
+ {\note{You cannot change the sample rate for digital recordings.}}
+
+ \opt{MASCODEC,x5}{
+ \item[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}{
+ \item[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.
+ }
+
+ \item[Time Split:]
+ This option is useful when timing recordings. If set to active it stops
+ a recording at a given interval and then starts recording again with a
+ new file, which is useful for long term recordings.
+ \newline
+ 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.
+ \newline
+ Options (hours:minutes between splits): off, 24:00, 18:00, 12:00, 10:00,
+ 8:00, 6:00, 4:00, 2:00, 1:20 (80 minute CD), 1:14 (74 minute CD), 1:00,
+ 00:30, 00:15, 00:10, 00:05.
+
+ \item[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.\\
+ Options: \setting{Off}, \setting{1 -- 30 seconds}
+
+ \item[Directory:]
+ Allows changing the location where the recorded files are saved. The
+ default location is \fname{/recordings}.
+
+ \item[Show recording screen on startup:]
+ If set to yes, the \dap\ will start up with the while recording screen
+ showing.\\
+ Options: \setting{Yes}, \setting{No}
+
+ \item[Clipping Light:]
+ Causes the backlight to flash on when clipping has been detected.\\
+ Options: \setting{Off}, \setting{Remote unit only},
+ \setting{Main and remote unit}, \setting{Main unit only}.
+
+ \opt{MASCODEC}{
+ \item[Trigger:]
+ \fixme{Add description of triggered recording.}
