| \section{Quality} |
| Choose the quality here (0 to 7). Default is 5, best quality is 7, |
| smallest file size is 0. This setting affects 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. |

| \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 whether 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 happen when the splitting condition is |
| fulfilled 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. |

| \setting{Main and remote unit}, \setting{Remote unit only}. |
| } |
| \section{Trigger} |
| When you record a source you often are only interested in the sound and not |
| the silence in between. The recording trigger provides you with a |
| tool to automatically distinguish between sound and silence and record the |
| sound only. Unfortunately it is not very easy to make this distinction between |
| silence and sound because you hardly ever encounter real silence. There always |
| are background noises. What is considered as background noise depends on the |
| situation. For example during a lecture the very low noise of rustling paper |
| might be considered as background noise. During a rock concert the murmur of |
| the audience might be considered background noise which is much louder compared |
| to rustling paper. Also the duration of the signal matters. When you record |
| speech you want to record every syllable. When you record live music you may |
| not be interested in that chord the guitarist plays for two minutes before |
| the show to verify his amp is turned on. The trigger features numerous |
| parameters to adapt its behaviour to the desired situation. |
| \begin{description} |
| \item[Trigger.] |
| This parameter specifies the trigger mode. When set to \setting{Off} |
| the recording must be started manually and apart from the Prerecord time no |
| other parameter has any effect. \setting{Once} will have the trigger start |
| one recording only; after the recording has finished the input signal will |
| not start another recording. \setting{Repeat} will have the trigger start |
| multiple recordings. |
| |
| \item[Trigtype.] |
| \fixme{Add description of Trigtype} |
| Options: \setting{Stop}, \setting{Pause}, \setting{New File}. |
| |
| \item[Prerecord Time.] |
| This specifies the time that is included into the recording before the |
| trigger event occurs. This is very useful if you record a signal that |
| fades in. Usually you want to set the prerecord time greater than or |
| equal to the start duration. That ensures that you record the entire |
| sound. Strictly speaking the prerecord time is not a special parameter |
| of the trigger. It is available during normal recordings too. |
| |
| \item[Start Above.] |
| The start threshold defines the minimal volume a sound must have to start the |
| recording. It is displayed numerically in the line ``Start Above''. Note that |
| the unit of the threshold depends on the settings of the peak meter. (i.e. |
| When the peak meter displays dB you can adjust the level in dB and when the |
| peak meter is set to linear the threshold is displayed as percentage.) In the |
| peak meter at the bottom of the screen the start threshold is displayed |
| graphically by a little triangle pointing to the right. There are two special |
| values. The value \setting{Off} turns the start condition off. With this |
| setting you have to start the recording manually and the trigger only stops |
| the recording according to the stop condition. The setting \setting{-inf} |
| sets the trigger to the absolute minimum. This setting only makes sense when |
| you record via a digital input as even the noise of the device itself would |
| exceed this threshold immediately. |
| |
| \item[for at least.] |
| The start duration defines the minimal duration that a signal must exceed the |
| start threshold to start the recording. Depending on your situation you may |
| want to set this setting to 0 (e.g. when copying a song from a commercial |
| medium) or to quite big values. Because sound is not continuous by nature |
| (think of percussion) negligible dropouts are tolerated during this start |
| duration. |
| |
| \item[Stop Below.] |
| When the sound level drops below the stop threshold the recording is stopped. |
| It is displayed numerically in the line ``Stop Below''. Just like the start |
| threshold the unit of the stop threshold depends on the settings of the peak |
| meter. There's also a small triangular marker in the peak meter at the bottom |
| of the screen. In contrast to the start threshold marker it points to the |
| left. The value \setting{Off} turns the stop condition off. With this setting you |
| have to stop the recording manually. |
| |
| \item[for at least.] |
| This time specifies the duration the signal must drop below the stop |
| threshold to stop the recording. By selecting high values you can ensure |
| that, for example, trailing fade-outs are recorded entirely. |
| |
| \item[Presplit Gap.] |
| When the signal drops below the stop threshold for the time specified by the |
| presplit gap a new recording may be started when the signal raises above the |
| start threshold. Thus the value of the presplit gap should be smaller than |
| the stop hold time. Otherwise the recording would stop anyway and the |
| presplit gap has no effect. For most uses I recommend to set this parameter |
| equal to the stop hold time. Sometimes you may encounter a sound source (e.g. |
| a CD) where the songs have fade outs and hardly any gaps between the tracks. |
| Here you can set the stop hold time to long values to ensure that all fade |
| outs are recorded completely. By specifying a short presplit gap you still |
| can split the recording into separate tracks whenever the trigger start |
| condition is met. |

| \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 (-1~dB) |
| 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 -9~dB and will slowly increase or decrease gain to reach it. |
| |
| \item[DJ-Set (slow).] |
| This preset heads for a nominal target peak level of -5~dB and will |
| slowly increase or decrease gain to reach it. |
| |
| \item[Medium.] |
| This preset heads for a nominal target peak level of -6~dB 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 -7~dB 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. |
