| screen}{} |
| |
| Entering the \setting{Recording} option in the \setting{Main Menu} brings up |
| a screen in which 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{SWCODEC}{ |
| \note{When you start a recording, the hard disk will spin up. This will cause |
| the peak meters to freeze in the process. This is expected behaviour, and |
| nothing to worry about. The recording continues during the spin up.}} |
| \opt{MASCODEC}{The frequency, channels and quality} |
| \opt{SWCODEC}{The frequency and channels} settings are shown on the last line. |

| \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{SWCODEC}{ |
| \item[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}. |
| |
| \item[Encoder Settings:] |
| This sets the bitrate when using the \setting{MPEG Layer 3} format. And has |
| no settings for the other formats. |
| } |
| |
| \item[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. |

| the sound is recorded using:\\ |
| MPEG v1 for 48, 44.1 and 32\\ |

| } |
| \opt{recorder,recorderv2fm,h1xx} |
| {\note{You cannot change the sample rate for digital recordings.} |
| } |
| |
| \item[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}.} |
| |
| \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[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} |
| |
| \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. |
| |
| \item[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. |
| |
| \item[Show recording screen on startup:] |
| If set to yes, the \dap{} will start up with the recording screen showing. |
| |
| \nopt{ondio}{ |
| \item[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}. |

| |
| \opt{h1xx,h300}{% |
| \item[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} |
| |
| \item[AGC clip time:] |
| This setting controls how long the level is too loud or soft before the |
| \setting{Automatic Gain Control} kicks in. |
