4Q. Who created abcde? Who develops it nowadays?
5A. It was originally created by Robert Woodcook. He decided to give up
6 maintaining it at some point in 2002 and Jesus Climent took over. Contact
7 jesus.climent@hispalinux.es if you have a problem or a suggestion.

11 ============
12
13Q. How can I install abcde on my system?
14A. To get abcde you can use a pre-packaged version, available for Debian,
15 FreeBSD, OpenBSD, NetBSD and others.
16 In case you want to install your own release, you need to download the
17 sources and install the complementary programs (abcde is just a frontend
18 and its functionality is provided by other programs).

272. EXECUTION
28 =========
29
b7f1cc84 30Q. Low on disk space?
31A. abcde has different algorithms to schedule ripping and encoding - to
32 optimize for disk conservation, use -l. You can also define
33 WAVOUTPUTDIR=/some/other/path to your /etc/abcde.conf or ~/.abcde.conf to
34 store the WAV files on another NFS shared fisk, for example.
35
36Q. How can i make abcde encode faster? My CD reader is way faster than the pace
37 it can encode my tracks.
38A. abcde can take advantage of SMP systems, just like make. Try 'abcde -j 2' -
39 it'll run two encoder jobs while it rips the next track.
40 You can also make use of systems which are networked, with the help of
41 distmp3. For example, MachineA has a better CPU power and MachineB has a CD
42 drive. Run distmp3host (included in distmp3) on Machine A, and then run
43 abcde -r MachineA from MachineB (where "MachineA" is a dns name or IP
44 address). Use this in combination with '-j 0' to shift all encoding off the
45 local machine.
46
81bc6204 47Q. I am having problems with *my CD reading program* reading the drive as a
48 user.
49A. You might have to add yourself (or the users who want to use abcde) to the
50 cdrom group and change the permissions of the cdrom device to 660. If you
51 have a SCSI cdrom drive, check the permissions of /dev/sg* as well.
c9c2ca27 52
53Q. I would like to give the trackname and the artist_name directly to the
54 encoder (in my case oggenc), but found no documentation.
55A. That is not possible, since abcde gets the information from CDDB database.
b7f1cc84 56 You can create a template and fill it with the option "-n". Also, you can
57 get the CDDB entry and edit it yourself. abcde has also an option to drop
58 back to a template if you like none of the CDDB entries, selecting 0 from
59 the CDDB options.
c9c2ca27 60
b7f1cc84 61Q. (Thanks to Amaya) Where are those options and settings defined? Why dont
62 you include a proper abcde.conf as an example?
63A. I do. It should be installed under /etc/abcde.conf and contains more or
64 less all the defaults abcde uses. You can use $(HOME)/.abcde.conf to
65 override those defaults. More information can be obtained from the man page
66 which can be consulted using "man abcde".
67
68Q. I keep on getting files with ".ogg.ogg" extension. What am I doing wrong?
69A. The code for multiple-output adds automatically the extension of the
70 different outputs you select with the "-o" extension (or with OUTPUTTYPE
71 variable). Erase the ".${OUTPUTTYPE}" part from the OUTPUTFORMAT variable
72 in /etc/abcde.conf or ~/.abcde.conf
73
74Q. I have modified some of the options, and now CDDB has stopped working.
75A. Check that you have modified everything in the right way. For instance, if
76 you modify the HTTPGET program you might want to set some options of your
77 own. If you use the predefined ones (wget, curl and fetch) abcde will try
78 to use some defaults. Keep in mind that the output should go to the output
79 as standard output, to be saved in a file for later use.
80
81 If abcde seems to be ignoring your configuration options or not running
82 commands such as the encoder, you may have misquoted something. Config
83 options such as the following do not work:
84
85 LAMEOPTS=-h -k
86
87 Try this instead:
88
89 LAMEOPTS='-h -k'
90
91Q. How can I separate the different output files I get using multiple-output
92 support?
93A. Use the OUTPUT variable in PLAYLISTFORMAT and OUTPUTFORMAT. It holds the
94 different output file types you passed to abcde (i.e., ogg, mp3, flac)
95 during playlist creation and file/directory creation.
c9c2ca27 96
97Q. I have a CD with a data track, and abcde complaints it cannot read/encode
98 it.
99A. It is not easy to find a data track on a CD. Right now, I can only think
100 of getting the track info from CDDB and ask the user for continuing should
101 a "data" track name is found. But the solution is far from been optimal.
102 For now, if you find a "data" track and you know the number, restart abcde
103 specifying the tracks to be encoded, leaving out the data one.
40c61684 104 Version 2.2 includes some checkings with cdparanoia, to try to get this
105 right.
c9c2ca27 106
b7f1cc84 107Q. I am requested to have "eject" when setting the speed although I do not use
108 it for anything.
109A. If you do not use cdparanoia, eject is used for setting the speed of the
110 cdrom drive. You can substitute it for "setcd" with "-x" as the argument,
111 but you have to install it manually (setcd is, at least, available in
112 Debian).
113 Another way to get the same results is using the pre_read function, defined
114 in your /etc/abcde.conf file.
c9c2ca27 115
b7f1cc84 116Q. I have a CD set with 1+ discs, and want to have them in the same directory,
117 sorted properly. What can abcde do for me?
118A. Set abcde to rip the first CD and give it the option "-t 101". Use a generic
119 name for the CD, and reuse it with the rest of the CDs, editing the CDDB
120 entries. Use "-t 201" for the second CD and so on. Use "-w <comment>" to
121 add a comment about the CD you are ripping (-w "disc #"). Alternatively you
122 can use only the "-t ###" option and then move all the files to the same
123 directory. If you want the tagged track number to be set to the modified
81bc6204 124 number you should use "-T ###". Even more! If you use "-W <cd_number>",
125 abcde will put a comment to every CD set ("CD <number>") and use modify the
126 number of the tracks.
b7f1cc84 127
128Q. I have a live concert. I want to encode it in a single file. How do i do it?
129A. Use "-1" and it will be encoded in a single file.
130
1313. CDDB
132 ====
133
134Q. I need to go through an HTTP proxy for CDDB access.
135A. No problem, just export your http_proxy variable first so wget/fetch/curl
136 can see it.
137
138Q. I already store CDDB entries in my hard disc. Can I make use of them?
139A. Piece of cake. Just edit CDDBLOCALDIR to point to the repository and give
140 abcde the "-L" flag to make use of it.
141
142Q. Fine, now it uses local CDDB, but I have no network connection. How can I
143 disable CDDB checks?
144A. Use the "-L -n" combination. It will try to use local CDDB entries, and if
145 nothing can be found, it will use a template. You will be also given the
146 choice to edit such template.
147
148Q. How can I use some other CDDB information provider?
149A. abcde now uses FreeDB by default. To use a different FreeDB mirror or
150 another CDDB service, change the CDDBURL option in your abcde.conf.
151
152
1533. FORMATS
154 =======
155
156Q. What formats can I encode my music to?
157A. As for version 2.2, abcde includes support for MP3, Ogg/Vorbis,
158 Ogg/Speex, Flac and MPP/MP+(Musepack). Support for AAC will be added once
159 an FLOSS encoder/decoder is working.
160
161Q. I want the new *put the newest and coolest codec there* format to be
162 supported by abcde. Abcde is so cool but i want to encode also to this
163 new format...
164A. Patches are welcome! ;)
165 No, seriously, if the format is usable, available for Linux and open
166 source/free software, it should be fairly easy to integrate. Support for
167 AAC (m4p) should be the next one to be introduced.
c9c2ca27 168
169Q. I use Debian/RedHat/(put your Unix flavour here) and MP3 encoding is not
170 working. What am I doing wrong?
171A. Since MP3 is considered non-free (you get it for free, but hardware players
172 and net broadcasters have to pay license fees), some release engineering
173 groups and release management teams have decided not to provide MP3 encoding
174 tools.
175 These distributions or operative systems have decided to use Ogg/Vorbis as
176 the default encoding format, since it contains no (known) patent claims
177 and they are (supposed to be) completely Free (released under a BSD-like
178 license).
179 However, there is no strong (at the moment) hardware support, although
180 some groups and companies are strongly working on getting it, real soon
181 now. For that reason some people prefer to encode to MP3.
182
183 UPDATE *** UPDATE
184 There are at least 3 known brands already selling Ogg/Vorbis portable
185 players: Rio, iRiver and Neuros.
186 Go buy one and you have no more reasons to use MP3.
187
188 If you are among those individuals, you might need to add support for MP3
189 encoding to your system:
190 Debian : check http://marillat.free.fr to install lame in your system.
191 others prefer bladeenc. Check www.apt-get.org or google.
192 RedHat : search on rpmfind.net
193 FreeBSD: By default includes LAME support.
194 OpenBSD: Available by specifying you want to install the port with LAME
195 support, or by just installing it later from the ports tree.
196 NetBSD : Available in pkgsrc.
197
198 Others : Please, help me here.
199
b7f1cc84 200Q. Huh! Why is MPPENCODER (with MPP) and .mpc the extension?
201A. Dunno. You must ask the guys who created and defined the format. The
202 standard is MPEGplus (MPP/MP+) but the files use .mpc extension.

2054. MISC PROBLEMS
206 ==== ========
79e3928b 207
b7f1cc84 208Q. What happened with normalize?
209A. Normalize has changed its name under Debian, which is the GNU/Linux
210 distribution for developing abcde (well, is The GNU/Linux Distribution
211 i only use, at the moment). Now it is called normalize-audio.
212 If you are using some other flavour of OS, you need to change the name
213 of the executable in your abcde.conf file.
79e3928b 214
b7f1cc84 215Q. I am using MacOSX and I am having problems to use abcde.
216A. Well, I have a Mac, but I use linux on it. I have not been able to find
217 a way to make it work there, since I do not have the development tools
218 installed. I have placed a basic support, but some user reports are just
219 complaining about abcde not encoding the ripped tracks, as if
220 cdda2wav/cdparanoia/cddafs would never end reading them. If you have such
221 a system and experience problems, please, report them, and I will try to
222 work them out with your help.
c9c2ca27 223
224Q. My hardware player (put it here) does not recognize the playlists created
225 with abcde. What I am doing wrong?
226A. Try using "-m" when creating the playlists, or setting DOSPLAYLIST as an
227 option in the config file.
228
c9c2ca27 229OBSOLETE
230--------
231Q. I set KEEPWAVS to "y" but abcde insists on erasing my directory, along
232 with the wav tracks. What I am doing wrong?
233A. The default action set includes clean, which cleans the temp directory,
234 if nothing goes wrong. Take the "clean" out from the action list and you
235 are done.
236 UPDATE: KEEPWAVS unselects now the clean action.
