2.SH NAME
3abcde \- Grab an entire CD and compress it to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+(Musepack) format.
4.SH SYNOPSIS
5.B abcde
6.I [options] [tracks]
7.SH DESCRIPTION
8Ordinarily, the process of grabbing the data off a CD and encoding it, then
9tagging or commenting it, is very involved.
10.BR abcde
11is designed to automate this. It will take an entire CD and convert it into
12a compressed audio format - Ogg/Vorbis, MPEG Audio Layer III, Free Lossless
13Audio Codec (FLAC), Ogg/Speex or MPP/MP+(Musepack). With one command, it will:
14.TP
15.B *
16Do a CDDB query over the Internet to look up your CD or use a locally stored CDDB entry
17.TP
18.B *
19Grab an audio track (or all the audio CD tracks) from your CD
20.TP
21.B *
22Normalize the volume of the individual file (or the album as a single unit)
23.TP
24.B *
25Compress to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+(Musepack) format(s), all in one CD read
26.TP
27.B *
28Comment or ID3/ID3v2 tag
29.TP
30.B *
31Give an intelligible filename
32.TP
33.B *
34Calculate replaygain values for the individual file (or the album as a single unit)
35.TP
36.B *
37Delete the intermediate WAV file (or save it for later use)
38.TP
39.B *
40Repeat until finished
41.SH OPTIONS
42.TP
43.B \-1
44Encode the whole CD in a single file. The resulting file uses the CD title
45for tagging. If the resulting format is a flac file with an embeded cuesheet,
46the file can be used as a source for creating other formats.
47.TP
48.B \-a [actions]
49Comma-delimited list of actions to perform. Can be one or more of:
50cddb, read, normalize, encode, tag, move, replaygain, playlist, clean. Normalize
51and encode imply read. Tag implies cddb, read, encode. Move implies
52cddb, read, encode, tag. Replaygain implies cddb, read, encode, tag and move.
53Playlist implies cddb. The default is to do all actions except normalize,
54replaygain and playlist.
55.TP
56.B \-b
57Enable batch mode normalization. See the BATCHNORM configuration variable.
58.TP
59.B \-B
60Disable batch mode replaygain. It processes file by file to add the replaygain
61information. See the NOBATCHREPLAYGAIN configuration vatiable.
62.TP
63.B \-c [filename]
64Specifies an additional configuration file to parse. Configuration options
65in this file override those in /etc/abcde.conf or $HOME/.abcde.conf.
66.TP
67.B \-C [discid]
68Allows you to resume a session for
69.I discid
70when you no longer have the CD available (abcde will automatically resume if
71you still have the CD in the drive). You must have already finished at
72least the "read" action during the previous session.
73.TP
74.B \-d [devicename | filename]
75CD\-ROM block device that contains audio tracks to be read. Alternatively, a
76single-track flac file with embeded cuesheet.
77.TP
78.B \-D
79Capture debugging information (you'll want to redirect this \- try 'abcde \-D
802>logfile')
81.TP
82.B \-e
83Erase information about encoded tracks from the internal status file, to enable
84other encodings if the wav files have been kept.
85.TP
86.B \-g
87Enable 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
89correctly display track lengths when playing variable-bit-rate mp3 files.
90.TP
91.B \-h
92Get help information.
93.TP
94.B \-j [number]
95Start [number] encoder processes at once. Useful for SMP systems. Overrides
96the MAXPROCS configuration variable. Set it to "0" when using distmp3 to avoid
97local encoding processes.
98.TP
99.B \-k
100Keep the wav files after encoding.
101.TP
102.B \-l
103Use the low-diskspace algorithm. See the LOWDISK configuration variable.
104.TP
105.B \-L
106Use a local CDDB repository. See CDDBLOCALDIR variable.
107.TP
108.B \-n
109Do not query CDDB database. Create and use a template. Edit the template to
110provide song names, artist(s), ...
111.TP
112.B \-N
113Non interactive mode. Do not ask anything from the user. Just go ahead.
114.TP
115.B \-m
116Create DOS-style playlists, modifying the resulting one by adding CRLF line
117endings. Some hardware players insist on having those to work.
118.TP
119.B \-M
120Create a CUE file with information about the CD. Together with the possibility
121of creating a single file (see option "\-1"), one can recreate the original CD.
122If the cuesheet is embeded in a flac single file it can be used as source for
123encoding other formats.
124.TP
125.B \-o [filetype][:filetypeoptions]
126Select 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
128types. See the OUTPUTTYPE configuration variable. One can pass options to the
129encoder for a specific filetype on the command line separating them with a
130colon. The options must be escaped with double-quotes.
131.TP
132.B \-p
133Pads track numbers with 0\'s.
134.TP
135.B \-r [hosts...]
136Remote encode on this comma-delimited list of machines using distmp3. See
137the REMOTEHOSTS configuration variable.
138.TP
139.B \-s [fields...]
140List, separated by comas, the fields to be shown in the CDDB parsed entries.
141Right now it only uses "year" and "genre".
142.TP
143.B \-S [speed]
144Set the speed of the CD drive. Needs CDSPEED and CDSPEEDOPTS set properly
145and both the program and device must support the capability.
146.TP
147.B \-t [number]
148Start the numbering of the tracks at a given number. It only affects the
149filenames and the playlist. Internal (tag) numbering remains the same.
150.TP
151.B \-T [number]
152Same as \-t but changes also the internal (tag) numbering. Keep in mind that
153the default TRACK tag for MP3 is $T/$TRACKS so it is changed to simply $T.
154.TP
155.B \-u
156Set CDDBPROTOCOL to version 6, so that we retrieve UTF-8 encoded CDDB
157information, and we tag and add comments with a proper encoding. This flag will
158be removed and -U will be added to set it to version 5 once version 6 becomes
159the default.
160.TP
161.B \-v
162Show the version and exit
163.TP
164.B \-V
165Be a bit more verbose. On slow networks the CDDB requests might give the
166sensation nothins is happening.
167.TP
168.B \-x
169Eject the CD when all tracks have been read. See the EJECTCD configuration
170variable.
171.TP
172.B \-w [comment]
173Add a comment to the tracks ripped from the CD.
174.TP
175.B \-W [number]
176Concatenate CD\'s. It uses the number provided to define a comment "CD #" and
177to modify the numbering of the tracks, starting with "#01".
178.TP
179.B \-z
180DEBUG mode: it will rip, using cdparanoia, the very first second of each track
181and proceed with the actions requested very quickly, also providing some
182"hidden" information about what happens on the background. CAUTION: IT WILL
183ERASE ANY EXISTING RIPS WITHOUT WARNING!
184.TP
185.B [tracks]
186A list of tracks you want abcde to process. If this isn't specified, abcde
187will process the entire CD. Accepts ranges of track numbers -
188"abcde 1-5 7 9" will process tracks 1, 2, 3, 4, 5, 7, and 9.
189.SH OUTPUT
190Each track is, by default, placed in a separate file named after the track
191in a subdirectory named after the artist under the current directory.
192This can be modified using the OUTPUTFORMAT and VAOUTPUTFORMAT
193variables in your abcde.conf. Each file is given an extension identifying
194its compression format, 'vorbis' for '.ogg', '.mp3', '.flac', '.spx', '.mpc', or '.wav'.
195.SH CONFIGURATION
196abcde sources two configuration files on startup - /etc/abcde.conf and
197$HOME/.abcde.conf, in that order.
198.TP
199The configuration options stated on those files can ba overriden by providing
200the appropiate flags at runtime.
201.TP
202The configuration variables have to be set as follows:
203.TP
204.B VARIABLE=value
205Except when "value" needs to be quoted or otherwise interpreted. If other
206variables within "value" are to be expanded upon reading the configuration
207file, then double quotes should be used. If they are only supposed to be
208expanded upon use (for example OUTPUTFORMAT) then single quotes must be used.
209.TP
210All sh escaping/quoting rules apply.
211.TP
212Here is a list of options abcde recognizes:
213.TP
214.B CDDBURL
215Specifies a server to use for CDDB lookups.
216.TP
217.B HELLOINFO
218Specifies the Hello information to send to the CDDB server. The CDDB
219protocol requires you to send a valid username and hostname each time you
220connect. The format of this is username@hostname.
221.TP
222.B CDDBLOCALDIR
223Specifies a directory where we store a local CDDB repository. The entries must
224be standard CDDB entries, with the filename being the DISCID value. Other
225CD playing and ripping programs (like Grip) store the entries under ~/.cddb
226and we can make use of those entries.
227.TP
228.B CDDBCOPYLOCAL
229Store local copies of the CDDB entries under the $CDDBLOCALDIR directory.
230.TP
231.B CDDBUSELOCAL
232Actually use the stored copies of the CDDB entries. Can be overriden using the
233"-L" flag (if is CDDBUSELOCAL in "n"). If an entry is found, we always give
234the choice of retrieving a CDDB entry from the internet.
235.TP
236.B SHOWCDDBFIELDS
237Coma-separated list of fields we want to parse during the CDDB parsing.
238Defaults to "year,genre".
239.TP
240.B OGGENCODERSYNTAX
241Specifies the style of encoder to use for the Ogg/Vorbis encoder. Valid options
242are \'oggenc\' (default for Ogg/Vorbis) and \'vorbize\'.
243This affects the default location of the binary,
244the variable to pick encoder command-line options from, and where the options
245are given.
246.TP
247.B MP3ENCODERSYNTAX
248Specifies the style of encoder to use for the MP3 encoder. Valid options are
249\'lame\' (default for MP3), \'gogo\', \'bladeenc\', \'l3enc\' and \'mp3enc\'.
250Affects the same way as explained above for Ogg/Vorbis.
251.TP
252.B FLACENCODERSYNTAX
253Specifies the style of encoder to use for the FLAC encoder. At this point only
254\'flac\' is available for FLAC encoding.
255.TP
256.B SPEEXENCODERSYNTAX
257Specifies the style of encoder to use for Speex encoder. At this point only
258\'speexenc\' is available for Ogg/Speex encoding.
259.TP
260.B MPPENCODERSYNTAX
261Specifies the style of encoder to use for MPP/MP+ (Musepack) encoder. At this
262point we only have \'mppenc\' available, from corecodecs.org.
263.TP
264.B NORMALIZERSYNTAX
265Specifies the style of normalizer to use. Valid options are \'default\'
266and \'normalize'\ (and both run \'normalize-audio\'), since we only support it,
267ATM.
268.TP
269.B CDROMREADERSYNTAX
270Specifies the style of cdrom reader to use. Valid options are \'cdparanoia\',
271\'debug\' and \'flac\'. It is used for querying the CDROM and obtain a list of
272valid tracks and DATA tracks. The special \'flac\' case is used to "rip" CD
273tracks from a single-track flac file.
274.TP
275.B CUEREADERSYNTAX
276Specifies the syntax of the program we use to read the CD CUE sheet. Right now
277we only support \'mkcue\', but in the future other readers might be used.
278.TP
279.B KEEPWAVS
280It defaults to no, so if you want to keep those wavs ripped from your CD,
281set it to "y". You can use the "-k" switch in the command line. The default
282behaviour with KEEPWAVS set is to keep the temporary directory and the wav
283files even you have requested the "clean" action.
284.TP
285.B PADTRACKS
286If set to "y", it adds 0's to the file numbers to complete a two-number
287holder. Useful when encoding tracks 1-9.
288.TP
289.B INTERACTIVE
290Set to "n" if you want to perform automatic rips, without user intervention.
291.TP
292.B NICE VALUES
293Define the values for priorities (nice values) for the different CPU-hungry
294processes: encoding (ENCNICE), CDROM read (READNICE) and distributed encoder
295with distmp3 (DISTMP3NICE).
296.TP
297.B PATHNAMES
298The following configuration file options specify the pathnames of their
299respective utilities: LAME, TOOLAME, GOGO, BLADEENC, L3ENC, XINGMP3ENC, MP3ENC,
300VORBIZE, OGGENC, FLAC, SPEEXENC, MPPENC, ID3, ID3V2, EYED3, METAFLAC,
301CDPARANOIA, CDDA2WAV, CDDAFS, CDDISCID, CDDBTOOL, EJECT, MD5SUM, DISTMP3,
302VORBISCOMMENT, NORMALIZE, CDSPEED, MP3GAIN, VORBISGAIN, MPPGAIN, MKCUE, MKTOC,
303DIFF and HTTPGET.
304.TP
305.B COMMAND-LINE OPTIONS
306If you wish to specify command-line options to any of the programs abcde uses,
307set the following configuration file options: LAMEOPTS, TOOLAMEOPTS, GOGOOPTS,
308BLADEENCOPTS, L3ENCOPTS, XINGMP3ENCOPTS, MP3ENCOPTS, VORBIZEOPTS, OGGENCOPTS,
309FLACOPTS, SPEEXENCOPTS, MPPENCOPTS, ID3OPTS, ID3V2OPTS, CDPARANOIAOPTS,
310CDDA2WAVOPTS, CDDAFSOPTS, CDDBTOOLOPTS, EJECTOPTS, DISTMP3OPTS, NORMALIZEOPTS,
311CDSPEEDOPTS, MKCUEOPTS, VORBISCOMMMENTOPTS, METAFLACOPTS, DIFFOPTS and
312HTTPGETOPTS.
313.TP
314.B CDSPEEDVALUE
315Set the value of the CDROM speed. The default is to read the disc as fast as
316the reading program and the system permits. The steps are defined as 150kB/s
317(1x).
318.TP
319.B ACTIONS
320The default actions to be performed when reading a disc.
321.TP
322.B CDROM
323If set, it points to the CD-Rom device which has to be used for audio
324extraction. Abcde tries to guess the right device, but it may fail. The special
325\'flac\' option is defined to extract tracks from a single-track flac file.
326.TP
327.B CDPARANOIACDROMBUS
328Defined as "d" when using cdparanoia with an IDE bus and as "g" when using
329cdparanoia with the ide-scsi emulation layer.
330.TP
331.B OUTPUTDIR
332Specifies the directory to place completed tracks/playlists in.
333.TP
334.B WAVOUTPUTDIR
335Specifies the temporary directory to store .wav files in. Abcde may use up
336to 700MB of temporary space for each session (although it is rare to use
337over 100MB for a machine that can encode music as fast as it can read it).
338.TP
339.B OUTPUTTYPE
340Specifies the encoding format to output, as well as the default extension and
341encoder. Defaults to "vorbis". Valid settings are "vorbis" (or "ogg")
342(Ogg/Vorbis), "mp3" (MPEG-1 Audio Layer III), "flac" (Free Lossless Audio
343Codec), "spx" (Ogg/Speex), "mpc" (MPP/MP+ (Musepack)) or "wav" (Microsoft
344Waveform). Values like "vorbis,mp3" encode the tracks in both Ogg/Vorbis and
345MP3 formats.
346.br
347For each value in OUTPUTTYPE, abcde expands a different process for encoding,
348tagging and moving, so you can use the format placeholder, OUTPUT, to create
349different subdirectories to hold the different types. The variable OUTPUT will
350be 'vorbis', 'mp3', 'flac', 'spx' and/or 'mpc', depending on the OUTPUTTYPE you define.
351For example
352.br
353OUTPUTFORMAT='${OUTPUT}/${ARTISTFILE}/${ALBUMFILE}/${TRACKNUM}._${TRACKFILE}'
354.TP
355.B OUTPUTFORMAT
356Specifies the format for completed Ogg/Vorbis, MP3, FLAC, Ogg/Speex or MPP/MP+
357(Musepack) filenames.
358Variables are included
359using standard shell syntax. Allowed variables are GENRE, ALBUMFILE, ARTISTFILE,
360TRACKFILE, TRACKNUM, and YEAR. Default is
361\'${ARTISTFILE}-${ALBUMFILE}/${TRACKNUM}-${TRACKFILE}\'.
362Make sure to use single quotes around this variable. TRACKNUM is
363automatically zero-padded, when the number of encoded tracks is higher than
3649. When lower, you can force with '-p' in the command line.
365.TP
366.B VAOUTPUTFORMAT
367Just like OUTPUTFORMAT but for Various Artists discs. Default is whatever
368OUTPUTFORMAT is set to.
369.TP
370.B MAXPROCS
371Defines how many encoders to run at once. This makes for huge speedups
372on SMP systems. You should run one encoder per CPU at once for maximum
373efficiency, although more doesn't hurt very much. Set it "0" when using
374mp3dist to avoid getting encoding processes in the local host.
375.TP
376.B LOWDISK
377If set to y, conserves disk space by encoding tracks immediately after
378reading them. This is substantially slower than normal operation but
379requires several hundred MB less space to complete the encoding of an
380entire CD. Use only if your system is low on space and cannot encode as
381quickly as it can read.
382.TP
383.B BATCHNORM
384If set to y, enables batch mode normalization, which preserves relative
385volume differences between tracks of an album. Also enables nogap encoding
386when using the \'lame\' encoder.
387.TP
388.B NOGAP
389Activate the lame's \-\-nogap option, that allows files found in CDs with no
390silence between songs (such as live concerts) to be encoded without noticeable
391gaps. WARNING: lame's \-\-nogap disables the Xing mp3 tag. This tag is
392required for mp3 players to correctly display track lengths when playing
393variable-bit-rate mp3 files.
394.TP
395.B PLAYLISTFORMAT
396Specifies the format for completed playlist filenames. Works like the
397OUTPUTFORMAT configuration variable. Default is
398\'${ARTISTFILE}_\-_${ALBUMFILE}.m3u\'.
399Make sure to use single quotes around this variable.
400.TP
401.B PLAYLISTDATAPREFIX
402Specifies a prefix for filenames within a playlist. Useful for http
403playlists, etc.
404.TP
405.B DOSPLAYLIST
406If set, the resulting playlist will have CR-LF line endings, needed by some
407hardware-based players.
408.TP
409.B COMMENT
410Specifies a comment to embed in the ID3 or Ogg comment field of each
411finished track. Can be up to 28 characters long. Supports the same
412syntax as OUTPUTFORMAT. Does not currently support ID3v2.
413.TP
414.B REMOTEHOSTS
415Specifies a comma-delimited list of systems to use for remote encoding using
416distmp3. Equivalent to -r.
417.TP
418.B mungefilename
419mungefilename() is an abcde shell function that can be overridden via
420abcde.conf. It takes CDDB data as $1 and outputs the resulting filename on
421stdout. It defaults to eating control characters, apostrophes and
422question marks, translating spaces and forward slashes to underscores, and
423translating colons to an underscore and a hyphen.
424.br
425If you modify this function, it is probably a good idea to keep the forward
426slash munging (UNIX cannot store a file with a '/' char in it) as well as
427the control character munging (NULs can't be in a filename either, and
428newlines and such in filenames are typically not desirable).
429.TP
430.B mungegenre
431mungegenre () is a shell function used to modify the $GENRE variable. As
432a default action, it takes $GENRE as $1 and outputs the resulting value
433to stdout converting all UPPERCASE characters to lowercase.
434.TP
435.B pre_read
436pre_read () is a shell function which is executed before the CDROM is read
437for the first time, during abcde execution. It can be used to close the CDROM
438tray, to set its speed (via "setcd" or via "eject", if available) and other
439preparation actions. The default function is empty.
440.TP
441.B post_read
442post_read () is a shell function which is executed after the CDROM is read
443(and, if applies, before the CDROM is ejected). It can be used to read a TOC
444from the CDROM, or to try to read the DATA areas from the CD (if any exist).
445The default function is empty.
446.TP
447.B EJECTCD
448If set to "y", abcde will call eject(1) to eject the cdrom from the drive
449after all tracks have been read. It has no effect when CDROM is set to a flac
450file.
451.TP
452.B EXTRAVERBOSE
453If set to "y", some operations which are usually now shown to the end user
454are visible, such as CDDB queries. Useful for initial debug and if your
455network/CDDB server is slow.
456.SH EXAMPLES
