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

70 | \item[Quality:] | ||
71 | Choose the quality here (0 to 7). Default is 5, best quality is 7, | ||
72 | smallest file size is 0. This setting effects how much your sound | ||
73 | sample will be compressed. Higher quality settings result in larger | ||
74 | MP3 files. | ||
75 | |||
76 | The quality setting is just a way of selecting an average bit rate, | ||
77 | or number of bits per second, for a recording. When this setting | ||
78 | is lowered, recordings are compressed more (meaning worse sound quality), | ||
79 | and the average bitrate changes as follows. | ||

96 | \opt{MASCODEC,x5}{ | ||
97 | \item[Frequency:] | ||
98 | Choose the recording frequency (sample rate) -- 48kHz, 44.1kHz, 32kHz and | ||
99 | 24kHz, 22.05kHz, 16kHz are available. Higher sample rates use up more disk | ||
100 | space, but give better sound quality. | ||
101 | This setting determines which frequency range can accurately be reproduced | ||
102 | during playback, Lower frequencies produce smaller files. | ||
103 | \opt{MASCODEC}{ | ||
104 | The frequency setting also determines which version of the MPEG standard | ||
105 | the sound is recorded using:\\ | ||
106 | MPEG v1 for 48, 44.1 and 32\\ | ||
107 | MPEG v2 for 24, 22.05 and 16\\ | ||
108 | } | ||
109 | } | ||
110 | \item[Source:] | ||
111 | Choose the source of the recording. This can be | ||
112 | \opt{recorder,recorderv2fm,h1xx}{SPDIF (digital),} microphone or line in. | ||
113 | \opt{CONFIG_TUNER}{For recording from the radio see page \pageref{ref:FMradio}.} | ||
114 | |||
115 | % Add h1xx here whenever it supports setting recording frequency. | ||
116 | \opt{recorder,recorderv2fm} | ||
117 | {\note{You cannot change the sample rate for digital recordings.}} | ||
118 | |||
119 | \opt{MASCODEC,x5}{ | ||
120 | \item[Channels:] | ||
121 | This allows you to select mono or stereo recording. Please note that | ||
122 | for mono recording, only the left channel is recorded. Mono recordings | ||
123 | are usually somewhat smaller than stereo. | ||
124 | } | ||
125 | |||
126 | \opt{MASCODEC}{ | ||
127 | \item[Independent Frames:] | ||
128 | The independent frames option tells the \dap\ to encode with the bit | ||
129 | reservoir disabled, so the frames are independent of each other. This | ||
130 | makes a file easier to edit. | ||
131 | } | ||
132 | |||
133 | \item[Time Split:] | ||
134 | This option is useful when timing recordings. If set to active it stops | ||
135 | a recording at a given interval and then starts recording again with a | ||
136 | new file, which is useful for long term recordings. | ||
137 | \newline | ||
138 | The splits are seamless (frame accurate), no audio is lost at the split | ||
139 | point. The break between recordings is only the time required to stop | ||
140 | and restart the recording, on the order of 2 -- 4 seconds. | ||
141 | \newline | ||
142 | Options (hours:minutes between splits): off, 24:00, 18:00, 12:00, 10:00, | ||
143 | 8:00, 6:00, 4:00, 2:00, 1:20 (80 minute CD), 1:14 (74 minute CD), 1:00, | ||
144 | 00:30, 00:15, 00:10, 00:05. | ||
145 | |||
146 | \item[Prerecord Time:] | ||
147 | This setting buffers a small amount of audio so that when the record button | ||
148 | is pressed, the recording will begin from that number of seconds earlier. | ||
149 | This is useful for ensuring that a recording begins before a cue that is | ||
150 | being waited for.\\ | ||
151 | Options: \setting{Off}, \setting{1 -- 30 seconds} | ||
152 | |||
153 | \item[Directory:] | ||
154 | Allows changing the location where the recorded files are saved. The | ||
155 | default location is \fname{/recordings}. | ||
156 | |||
157 | \item[Show recording screen on startup:] | ||
158 | If set to yes, the \dap\ will start up with the while recording screen | ||
159 | showing.\\ | ||
160 | Options: \setting{Yes}, \setting{No} | ||
161 | |||
162 | \item[Clipping Light:] | ||
163 | Causes the backlight to flash on when clipping has been detected.\\ | ||
164 | Options: \setting{Off}, \setting{Remote unit only}, | ||
165 | \setting{Main and remote unit}, \setting{Main unit only}. | ||
166 | |||
