6 .I [options] [tracks]
8 Ordinarily, the process of grabbing the data off a CD and encoding it, then
9 tagging or commenting it, is very involved.
10 .BR abcde
11 is designed to automate this. It will take an entire CD and convert it into
12 a compressed audio format - Ogg/Vorbis, MPEG Audio Layer III, Free Lossless
13 Audio Codec (FLAC), Ogg/Speex or MPP/MP+(Musepack). With one command, it will:
14 .TP
15 .B *
16 Do a CDDB query over the Internet to look up your CD or use a locally stored CDDB entry
17 .TP
18 .B *
19 Grab an audio track (or all the audio CD tracks) from your CD
20 .TP
21 .B *
22 Normalize the volume of the individual file (or the album as a single unit)
23 .TP
24 .B *
25 Compress to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+(Musepack) format(s), all in one CD read

37 Delete the intermediate WAV file (or save it for later use)
38 .TP
39 .B *
40 Repeat until finished
42 .TP
43 .B \-1
44 Encode the whole CD in a single file. The resulting file uses the CD title
45 for tagging. If the resulting format is a flac file with an embeded cuesheet,
46 the file can be used as a source for creating other formats.
47 .TP
48 .B \-a [actions]
49 Comma-delimited list of actions to perform. Can be one or more of:
50 cddb, read, normalize, encode, tag, move, replaygain, playlist, clean. Normalize
51 and encode imply read. Tag implies cddb, read, encode. Move implies
52 cddb, read, encode, tag. Replaygain implies cddb, read, encode, tag and move.
53 Playlist implies cddb. The default is to do all actions except normalize,
54 replaygain and playlist.
55 .TP
56 .B \-b
57 Enable batch mode normalization. See the BATCHNORM configuration variable.
58 .TP
59 .B \-B
60 Disable batch mode replaygain. It processes file by file to add the replaygain
61 information. See the NOBATCHREPLAYGAIN configuration vatiable.
62 .TP
63 .B \-c [filename]
64 Specifies an additional configuration file to parse. Configuration options
65 in this file override those in /etc/abcde.conf or $HOME/.abcde.conf.
66 .TP
67 .B \-C [discid]
68 Allows you to resume a session for
69 .I discid
70 when you no longer have the CD available (abcde will automatically resume if
71 you still have the CD in the drive). You must have already finished at
72 least the "read" action during the previous session.
73 .TP
74 .B \-d [devicename | filename]
75 CD\-ROM block device that contains audio tracks to be read. Alternatively, a
76 single-track flac file with embeded cuesheet.
77 .TP
78 .B \-D
79 Capture debugging information (you'll want to redirect this \- try 'abcde \-D
80 2>logfile')
81 .TP
82 .B \-e
83 Erase information about encoded tracks from the internal status file, to enable
84 other encodings if the wav files have been kept.
85 .TP
86 .B \-g
87 Enable lame's \-\-nogap option. See the NOGAP variable. WARNING: lame's
88 \-\-nogap disables the Xing mp3 tag. This tag is required for mp3 players to
89 correctly display track lengths when playing variable-bit-rate mp3 files.
90 .TP
91 .B \-h
92 Get help information.
93 .TP
94 .B \-j [number]
95 Start [number] encoder processes at once. Useful for SMP systems. Overrides
96 the MAXPROCS configuration variable. Set it to "0" when using distmp3 to avoid
97 local encoding processes.
98 .TP
99 .B \-k
100 Keep the wav files after encoding.
101 .TP
102 .B \-l
103 Use the low-diskspace algorithm. See the LOWDISK configuration variable.
104 .TP
105 .B \-L
106 Use a local CDDB repository. See CDDBLOCALDIR variable.
107 .TP
108 .B \-n
109 Do not query CDDB database. Create and use a template. Edit the template to
110 provide song names, artist(s), ...
111 .TP
112 .B \-N
113 Non interactive mode. Do not ask anything from the user. Just go ahead.
114 .TP
115 .B \-m
116 Create DOS-style playlists, modifying the resulting one by adding CRLF line
117 endings. Some hardware players insist on having those to work.
118 .TP
119 .B \-M
120 Create a CUE file with information about the CD. Together with the possibility
121 of creating a single file (see option "\-1"), one can recreate the original CD.
122 If the cuesheet is embeded in a flac single file it can be used as source for
123 encoding other formats.
124 .TP
125 .B \-o [filetype][:filetypeoptions]
126 Select output type. Can be "vorbis" (or "ogg"), "mp3", "flac", "spx", "mpc" or
127 "wav". Specify a comma-delimited list of output types to obtain all specified
128 types. See the OUTPUTTYPE configuration variable. One can pass options to the
129 encoder for a specific filetype on the command line separating them with a
130 colon. The options must be escaped with double-quotes.
131 .TP
132 .B \-p
133 Pads track numbers with 0\'s.
134 .TP
135 .B \-r [hosts...]
136 Remote encode on this comma-delimited list of machines using distmp3. See
137 the REMOTEHOSTS configuration variable.
138 .TP
139 .B \-s [fields...]
140 List, separated by comas, the fields to be shown in the CDDB parsed entries.
141 Right now it only uses "year" and "genre".
142 .TP
143 .B \-S [speed]
144 Set the speed of the CD drive. Needs CDSPEED and CDSPEEDOPTS set properly
145 and both the program and device must support the capability.
146 .TP
147 .B \-t [number]
148 Start the numbering of the tracks at a given number. It only affects the
149 filenames and the playlist. Internal (tag) numbering remains the same.
150 .TP
151 .B \-T [number]
152 Same as \-t but changes also the internal (tag) numbering. Keep in mind that
153 the default TRACK tag for MP3 is $T/$TRACKS so it is changed to simply $T.
154 .TP
155 .B \-v
156 Show the version and exit
157 .TP
158 .B \-V
159 Be a bit more verbose. On slow networks the CDDB requests might give the
160 sensation nothins is happening.
161 .TP
162 .B \-x
163 Eject the CD when all tracks have been read. See the EJECTCD configuration
164 variable.
165 .TP
166 .B \-w [comment]
167 Add a comment to the tracks ripped from the CD.
168 .TP
169 .B \-W [number]
170 Concatenate CD\'s. It uses the number provided to define a comment "CD #" and
171 to modify the numbering of the tracks, starting with "#01".
172 .TP
173 .B [tracks]
174 A list of tracks you want abcde to process. If this isn't specified, abcde
175 will process the entire CD. Accepts ranges of track numbers -
176 "abcde 1-5 7 9" will process tracks 1, 2, 3, 4, 5, 7, and 9.
178 Each track is, by default, placed in a separate file named after the track
179 in a subdirectory named after the artist under the current directory.
180 This can be modified using the OUTPUTFORMAT and VAOUTPUTFORMAT
181 variables in your abcde.conf. Each file is given an extension identifying
182 its compression format, 'vorbis' for '.ogg', '.mp3', '.flac', '.spx', '.mpc', or '.wav'.
184 abcde sources two configuration files on startup - /etc/abcde.conf and
185 $HOME/.abcde.conf, in that order.
186 .TP
187 The configuration options stated on those files can ba overriden by providing
188 the appropiate flags at runtime.
189 .TP
190 The configuration variables have to be set as follows:
191 .TP
192 .B VARIABLE=value
193 Except when "value" needs to be quoted or otherwise interpreted. If other
194 variables within "value" are to be expanded upon reading the configuration
195 file, then double quotes should be used. If they are only supposed to be
196 expanded upon use (for example OUTPUTFORMAT) then single quotes must be used.
197 .TP
198 All sh escaping/quoting rules apply.
199 .TP
200 Here is a list of options abcde recognizes:
201 .TP
203 Specifies a server to use for CDDB lookups.
204 .TP
206 Specifies the Hello information to send to the CDDB server. The CDDB
207 protocol requires you to send a valid username and hostname each time you
208 connect. The format of this is username@hostname.
209 .TP
211 Specifies a directory where we store a local CDDB repository. The entries must
212 be standard CDDB entries, with the filename being the DISCID value. Other
213 CD playing and ripping programs (like Grip) store the entries under ~/.cddb
214 and we can make use of those entries.
215 .TP
217 Store local copies of the CDDB entries under the $CDDBLOCALDIR directory.
218 .TP
220 Actually use the stored copies of the CDDB entries. Can be overriden using the
221 "-L" flag (if is CDDBUSELOCAL in "n"). If an entry is found, we always give
222 the choice of retrieving a CDDB entry from the internet.
223 .TP
225 Coma-separated list of fields we want to parse during the CDDB parsing.
226 Defaults to "year,genre".
227 .TP
229 Specifies the style of encoder to use for the Ogg/Vorbis encoder. Valid options
230 are \'oggenc\' (default for Ogg/Vorbis) and \'vorbize\'.
231 This affects the default location of the binary,
232 the variable to pick encoder command-line options from, and where the options
233 are given.
234 .TP
236 Specifies the style of encoder to use for the MP3 encoder. Valid options are
237 \'lame\' (default for MP3), \'gogo\', \'bladeenc\', \'l3enc\' and \'mp3enc\'.
238 Affects the same way as explained above for Ogg/Vorbis.
239 .TP
241 Specifies the style of encoder to use for the FLAC encoder. At this point only
242 \'flac\' is available for FLAC encoding.
243 .TP
245 Specifies the style of encoder to use for Speex encoder. At this point only
246 \'speexenc\' is available for Ogg/Speex encoding.
247 .TP
249 Specifies the style of encoder to use for MPP/MP+ (Musepack) encoder. At this
250 point we only have \'mppenc\' available, from corecodecs.org.
251 .TP
253 Specifies the style of normalizer to use. Valid options are \'default\'
254 and \'normalize'\ (and both run \'normalize-audio\'), since we only support it,
255 ATM.
256 .TP
258 Specifies the style of cdrom reader to use. Valid options are \'cdparanoia\',
259 \'debug\' and \'flac\'. It is used for querying the CDROM and obtain a list of
260 valid tracks and DATA tracks. The special \'flac\' case is used to "rip" CD
261 tracks from a single-track flac file.
262 .TP
264 Specifies the syntax of the program we use to read the CD CUE sheet. Right now
265 we only support \'mkcue\', but in the future other readers might be used.
266 .TP
268 It defaults to no, so if you want to keep those wavs ripped from your CD,
269 set it to "y". You can use the "-k" switch in the command line. The default
270 behaviour with KEEPWAVS set is to keep the temporary directory and the wav
271 files even you have requested the "clean" action.
272 .TP
274 If set to "y", it adds 0's to the file numbers to complete a two-number
275 holder. Useful when encoding tracks 1-9.
276 .TP
278 Set to "n" if you want to perform automatic rips, without user intervention.
279 .TP
281 Define the values for priorities (nice values) for the different CPU-hungry
282 processes: encoding (ENCNICE), CDROM read (READNICE) and distributed encoder
283 with distmp3 (DISTMP3NICE).
284 .TP
286 The following configuration file options specify the pathnames of their
287 respective utilities: LAME, TOOLAME, GOGO, BLADEENC, L3ENC, XINGMP3ENC, MP3ENC,
291 .TP
293 If you wish to specify command-line options to any of the programs abcde uses,
294 set the following configuration file options: LAMEOPTS, TOOLAMEOPTS, GOGOOPTS,
300 .TP
302 Set the value of the CDROM speed. The default is to read the disc as fast as
303 the reading program and the system permits. The steps are defined as 150kB/s
304 (1x).
305 .TP
307 The default actions to be performed when reading a disc.
308 .TP
309 .B CDROM
310 If set, it points to the CD-Rom device which has to be used for audio
311 extraction. Abcde tries to guess the right device, but it may fail. The special
312 \'flac\' option is defined to extract tracks from a single-track flac file.
313 .TP
315 Defined as "d" when using cdparanoia with an IDE bus and as "g" when using
316 cdparanoia with the ide-scsi emulation layer.
317 .TP
319 Specifies the directory to place completed tracks/playlists in.
320 .TP
322 Specifies the temporary directory to store .wav files in. Abcde may use up
323 to 700MB of temporary space for each session (although it is rare to use
324 over 100MB for a machine that can encode music as fast as it can read it).
325 .TP
327 Specifies the encoding format to output, as well as the default extension and
328 encoder. Defaults to "vorbis". Valid settings are "vorbis" (or "ogg")
329 (Ogg/Vorbis), "mp3" (MPEG-1 Audio Layer III), "flac" (Free Lossless Audio
330 Codec), "spx" (Ogg/Speex), "mpc" (MPP/MP+ (Musepack)) or "wav" (Microsoft
331 Waveform). Values like "vorbis,mp3" encode the tracks in both Ogg/Vorbis and
332 MP3 formats.
333 .br
334 For each value in OUTPUTTYPE, abcde expands a different process for encoding,
335 tagging and moving, so you can use the format placeholder, OUTPUT, to create
336 different subdirectories to hold the different types. The variable OUTPUT will
337 be 'vorbis', 'mp3', 'flac', 'spx' and/or 'mpc', depending on the OUTPUTTYPE you define.
338 For example
339 .br
341 .TP
343 Specifies the format for completed Ogg/Vorbis, MP3, FLAC, Ogg/Speex or MPP/MP+
344 (Musepack) filenames.
345 Variables are included
346 using standard shell syntax. Allowed variables are GENRE, ALBUMFILE, ARTISTFILE,
347 TRACKFILE, TRACKNUM, and YEAR. Default is
349 Make sure to use single quotes around this variable. TRACKNUM is
350 automatically zero-padded, when the number of encoded tracks is higher than
351 9. When lower, you can force with '-p' in the command line.
352 .TP
354 Just like OUTPUTFORMAT but for Various Artists discs. Default is whatever
355 OUTPUTFORMAT is set to.
356 .TP
358 Defines how many encoders to run at once. This makes for huge speedups
359 on SMP systems. You should run one encoder per CPU at once for maximum
360 efficiency, although more doesn't hurt very much. Set it "0" when using
361 mp3dist to avoid getting encoding processes in the local host.
362 .TP
364 If set to y, conserves disk space by encoding tracks immediately after
365 reading them. This is substantially slower than normal operation but
366 requires several hundred MB less space to complete the encoding of an
367 entire CD. Use only if your system is low on space and cannot encode as
368 quickly as it can read.
369 .TP
371 If set to y, enables batch mode normalization, which preserves relative
372 volume differences between tracks of an album. Also enables nogap encoding
373 when using the \'lame\' encoder.
374 .TP
375 .B NOGAP
376 Activate the lame's \-\-nogap option, that allows files found in CDs with no
377 silence between songs (such as live concerts) to be encoded without noticeable
378 gaps. WARNING: lame's \-\-nogap disables the Xing mp3 tag. This tag is
379 required for mp3 players to correctly display track lengths when playing
380 variable-bit-rate mp3 files.
381 .TP
383 Specifies the format for completed playlist filenames. Works like the
384 OUTPUTFORMAT configuration variable. Default is
385 \'${ARTISTFILE}_\-_${ALBUMFILE}.m3u\'.
386 Make sure to use single quotes around this variable.
387 .TP
389 Specifies a prefix for filenames within a playlist. Useful for http
390 playlists, etc.
391 .TP
393 If set, the resulting playlist will have CR-LF line endings, needed by some
394 hardware-based players.
395 .TP
397 Specifies a comment to embed in the ID3 or Ogg comment field of each
398 finished track. Can be up to 28 characters long. Supports the same
399 syntax as OUTPUTFORMAT. Does not currently support ID3v2.
400 .TP
402 Specifies a comma-delimited list of systems to use for remote encoding using
403 distmp3. Equivalent to -r.
404 .TP
405 .B mungefilename
406 mungefilename() is an abcde shell function that can be overridden via
407 abcde.conf. It takes CDDB data as $1 and outputs the resulting filename on
408 stdout. It defaults to eating control characters, apostrophes and
409 question marks, translating spaces and forward slashes to underscores, and
410 translating colons to an underscore and a hyphen.
411 .br
412 If you modify this function, it is probably a good idea to keep the forward
413 slash munging (UNIX cannot store a file with a '/' char in it) as well as
414 the control character munging (NULs can't be in a filename either, and
415 newlines and such in filenames are typically not desirable).
416 .TP
417 .B mungegenre
418 mungegenre () is a shell function used to modify the $GENRE variable. As
419 a default action, it takes $GENRE as $1 and outputs the resulting value
420 to stdout converting all UPPERCASE characters to lowercase.
421 .TP
422 .B pre_read
423 pre_read () is a shell function which is executed before the CDROM is read
424 for the first time, during abcde execution. It can be used to close the CDROM
425 tray, to set its speed (via "setcd" or via "eject", if available) and other
426 preparation actions. The default function is empty.
427 .TP
428 .B post_read
429 post_read () is a shell function which is executed after the CDROM is read
430 (and, if applies, before the CDROM is ejected). It can be used to read a TOC
431 from the CDROM, or to try to read the DATA areas from the CD (if any exist).
432 The default function is empty.
433 .TP
435 If set to "y", abcde will call eject(1) to eject the cdrom from the drive
436 after all tracks have been read. It has no effect when CDROM is set to a flac
437 file.
438 .TP
440 If set to "y", some operations which are usually now shown to the end user
441 are visible, such as CDDB queries. Useful for initial debug and if your
442 network/CDDB server is slow.
444 Possible ways one can call abcde
445 .TP
446 .B abcde
447 Will work in most systems
448 .TP
449 .B abcde \-d /dev/cdrom2
450 If the CDROM you are reding from is not the standard /dev/cdrom (in GNU/Linux systems)
451 .TP
452 .B abcde \-o vorbis,flac
453 Will create both Ogg/Vorbis and Ogg/FLAC files.
454 .TP
455 .B abcde \-o vorbis:"-b 192"
456 Will pass "-b 192" to the Ogg/Vorbis encoder, without having to modify the
457 config file
458 .TP
459 .B abcde \-W 1
460 For double+ CD settings: will create the 1st CD starting with the track number
461 101, and will add a comment "CD 1" to the tracks, the second starting with 201
462 and so on.
463 .TP
464 .B abcde \-d singletrack.flac
465 Will extract the files contained in singletrack using the embeded cuesheet.
467 abcde requires the following backend tools to work:
468 .TP
469 .B *
470 An Ogg/Vorbis, MP3, FLAC, Ogg/Speex or MPP/MP+(Musepack) encoder (oggenc, vorbize, lame, gogo, bladeenc, l3enc, mp3enc, flac, speexenc, mppenc)
