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.

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. \end{description} \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 \end{tabularx} \end{center} \end{table} } \begin{description} \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.} } \end{description}
