5 | \section{Quality} | ||
6 | Choose the quality here (0 to 7). Default is 5, best quality is 7, | ||
7 | smallest file size is 0. This setting effects how much your sound | ||
8 | sample will be compressed. Higher quality settings result in larger | ||
9 | MP3 files. | ||
10 | |||
11 | The quality setting is just a way of selecting an average bit rate, | ||
12 | or number of bits per second, for a recording. When this setting | ||
13 | is lowered, recordings are compressed more (meaning worse sound quality), | ||
14 | and the average bitrate changes as follows. | ||

30 | \section{Format} | ||
31 | Choose which format to save your recording in. The available choices are | ||
32 | the two uncompressed formats \setting{PCM Wave} and \setting{AIFF}, the | ||
33 | losslessly compressed \setting{WavPack} and the lossy | ||
34 | \setting{MPEG Layer 3}. | ||

38 | no settings for the other formats. | ||
39 | } | ||
40 | |||
41 | \section{Frequency} | ||
42 | Choose the recording frequency (sample rate). | ||
43 | \opt{MASCODEC}{48kHz, 44.1kHz, 32kHz, 24kHz, 22.05kHz, 16kHz} | ||

45 | \opt{x5}{88.2kHz, 44.1kHz, 22.05kHz and 11.025kHz} | ||
46 | are available. Higher sample rates use up more disk space, but give better | ||

61 | \section{Source} | ||
62 | Choose the source of the recording. This can be | ||
63 | \opt{recorder,recorderv2fm,h1xx}{\setting{SPDIF (digital)},}% | ||
64 | \setting{Mic} or \setting{Line In}. | ||
65 | \opt{CONFIG_TUNER}{For recording from the radio see \reference{ref:FMradio}.} | ||
66 | |||
67 | \section{Channels} | ||
68 | This allows you to select mono or stereo recording. Please note that | ||
69 | for mono recording, only the left channel is recorded. Mono recordings | ||
70 | are usually somewhat smaller than stereo. | ||

72 | \opt{MASCODEC}{ | ||
73 | \section{Independent Frames} | ||
74 | The independent frames option tells the \dap{} to encode with the bit | ||
75 | reservoir disabled, so the frames are independent of each other. This | ||
76 | makes a file easier to edit. | ||
77 | } | ||
78 | |||
79 | \section{File Split Options} | ||
80 | This sub menu contains options for file splitting, which can be used to split | ||
81 | up long recordings into manageable pieces. The splits are seamless (frame | ||
82 | accurate), no audio is lost at the split point. The break between recordings | ||
83 | is only the time required to stop and restart the recording, on the order of | ||
84 | 2 -- 4 seconds. | ||
85 | \begin{description} | ||
86 | \item[Split Measure:] | ||
87 | This option controls wether to split the recording when the | ||
88 | \setting{Split Filesize} is reached or when the | ||
89 | \setting{Split Time} has elapsed. | ||
90 | |||
91 | \item[What to do when Splitting:] | ||
92 | This controls what will happend when the splitting condition is | ||
93 | fullfilled the two available options here are | ||
94 | \setting{Start a new file} or \setting{Stop recording}. | ||
95 | |||
96 | \item[Split Time:] | ||
97 | Set the time to record between each split, if time is used as | ||
98 | \setting{Split Measure}.\\ | ||
99 | Options (hours:minutes between splits): Off, 00:05, 00:10, 00:15, 00:30, | ||
100 | 1:00, 1:14 (74 minute CD), 1:20 (80 minute CD), 2:00, 4:00, 8:00, 10:00, | ||
101 | 12:00, 18:00, 24:00. | ||
102 | |||
103 | \item[Split Filesize:] | ||
104 | Set the filesize to record between each split, if filesize is used as | ||
105 | \setting{Split Measure}. | ||
106 | |||
107 | \end{description} | ||
108 | |||
109 | \section{Prerecord Time} | ||
110 | This setting buffers a small amount of audio so that when the record button | ||
111 | is pressed, the recording will begin from that number of seconds earlier. | ||
112 | This is useful for ensuring that a recording begins before a cue that is | ||
113 | being waited for. | ||
114 | |||
115 | \section{Directory} | ||
116 | Allows changing the location where the recorded files are saved. The | ||
117 | default location is \fname{/recordings}. If set to | ||
118 | \setting{Current Directory} the recorded files will be saved in the | ||
119 | directory where the \setting{File Browser} was left. | ||

131 | \section{Automatic Gain Control} | ||
132 | The \setting{Automatic Gain Control} has five different presets for | ||
133 | automatically controlling the gain while recording. | ||
134 | \begin{description} | ||
135 | \item[Safety (clip):] | ||
136 | This preset will lower the gain when the levels get too high (-1dB) | ||
137 | and will never increase gain. | ||
138 | |||
139 | \item[Live (slow):] | ||
140 | This preset is designed to be used for recording of live shows and has | ||
141 | quite large headroom for loud parts. It heads for a nominal target peak | ||
142 | level of -9dB and will slowly increase or decrease gain to reach it. | ||
143 | |||
144 | \item[DJ-Set (slow):] | ||
145 | This preset heads for a nominal target peak level of -5dB and will | ||
146 | slowly increase or decrease gain to reach it. | ||
147 | |||
148 | \item[Medium:] | ||
149 | This preset heads for a nominal target peak level of -6dB and will | ||
150 | increase or decrease gain to reach it. | ||
151 | |||
152 | \item[Voice (fast):] | ||
153 | This preset is designed to be used for voice recording and heads for a | ||
154 | nominal target peak level of -7dB and will quickly increase or | ||
155 | decrease gain to reach it. | ||
156 | \end{description} | ||
157 | |||
158 | \section{AGC clip time} | ||
159 | This setting controls how long the level is too loud or soft before the | ||
160 | \setting{Automatic Gain Control} kicks in. | ||
