2 ============
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 if you have a problem or a suggestion.

79e3928b 101. INSTALLATION
11 ============
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).
79e3928b 19
20 abcde needs cd-discid. Grab it from:

fd34b28b 25Q. I have a problem, and I reported some time ago. Have you solved it already?
26A. Maybe. Try downloading the trunk of the development from
79e3928b 28
fd34b28b 29Q. When are you going to release a new version?
30A. When it is ready. I keep on having new ideas and adding them to the trunk
31 (stored in the URL above), so I dont release until all the ideas are
32 finished.
79e3928b 34
36 =========
b7f1cc84 38Q. Low on disk space?
39A. abcde has different algorithms to schedule ripping and encoding - to
40 optimize for disk conservation, use -l. You can also define
41 WAVOUTPUTDIR=/some/other/path to your /etc/abcde.conf or ~/.abcde.conf to
42 store the WAV files on another NFS shared fisk, for example.
fd34b28b 43 Also, UNIX pipes have also been implemented, using "-P", so abcde reads and
44 encodes the tracks from the CD at once. However, it has the drawback that
45 only one format can be encoded at a time.
b7f1cc84 46
47Q. How can i make abcde encode faster? My CD reader is way faster than the pace
48 it can encode my tracks.
49A. abcde can take advantage of SMP systems, just like make. Try 'abcde -j 2' -
50 it'll run two encoder jobs while it rips the next track.
51 You can also make use of systems which are networked, with the help of
52 distmp3. For example, MachineA has a better CPU power and MachineB has a CD
53 drive. Run distmp3host (included in distmp3) on Machine A, and then run
54 abcde -r MachineA from MachineB (where "MachineA" is a dns name or IP
55 address). Use this in combination with '-j 0' to shift all encoding off the
56 local machine.
81bc6204 58Q. I am having problems with *my CD reading program* reading the drive as a
59 user.
60A. You might have to add yourself (or the users who want to use abcde) to the
61 cdrom group and change the permissions of the cdrom device to 660. If you
62 have a SCSI cdrom drive, check the permissions of /dev/sg* as well.
c9c2ca27 63
64Q. I would like to give the trackname and the artist_name directly to the
65 encoder (in my case oggenc), but found no documentation.
66A. That is not possible, since abcde gets the information from CDDB database.
b7f1cc84 67 You can create a template and fill it with the option "-n". Also, you can
68 get the CDDB entry and edit it yourself. abcde has also an option to drop
69 back to a template if you like none of the CDDB entries, selecting 0 from
70 the CDDB options.
c9c2ca27 71
b7f1cc84 72Q. (Thanks to Amaya) Where are those options and settings defined? Why dont
73 you include a proper abcde.conf as an example?
74A. I do. It should be installed under /etc/abcde.conf and contains more or
75 less all the defaults abcde uses. You can use $(HOME)/.abcde.conf to
76 override those defaults. More information can be obtained from the man page
77 which can be consulted using "man abcde".
79Q. I keep on getting files with ".ogg.ogg" extension. What am I doing wrong?
80A. The code for multiple-output adds automatically the extension of the
81 different outputs you select with the "-o" extension (or with OUTPUTTYPE
82 variable). Erase the ".${OUTPUTTYPE}" part from the OUTPUTFORMAT variable
83 in /etc/abcde.conf or ~/.abcde.conf
85Q. I have modified some of the options, and now CDDB has stopped working.
86A. Check that you have modified everything in the right way. For instance, if
87 you modify the HTTPGET program you might want to set some options of your
88 own. If you use the predefined ones (wget, curl and fetch) abcde will try
89 to use some defaults. Keep in mind that the output should go to the output
90 as standard output, to be saved in a file for later use.
92 If abcde seems to be ignoring your configuration options or not running
93 commands such as the encoder, you may have misquoted something. Config
94 options such as the following do not work:
96 LAMEOPTS=-h -k
98 Try this instead:
100 LAMEOPTS='-h -k'
102Q. How can I separate the different output files I get using multiple-output
103 support?
104A. Use the OUTPUT variable in PLAYLISTFORMAT and OUTPUTFORMAT. It holds the
105 different output file types you passed to abcde (i.e., ogg, mp3, flac)
106 during playlist creation and file/directory creation.
c9c2ca27 107
108Q. I have a CD with a data track, and abcde complaints it cannot read/encode
109 it.
110A. It is not easy to find a data track on a CD. Right now, I can only think
111 of getting the track info from CDDB and ask the user for continuing should
112 a "data" track name is found. But the solution is far from been optimal.
113 For now, if you find a "data" track and you know the number, restart abcde
114 specifying the tracks to be encoded, leaving out the data one.
fd34b28b 115 From version 2.2 onwards, abcde includes some checkings with cdparanoia, to
116 try to get this right.
c9c2ca27 117
b7f1cc84 118Q. I am requested to have "eject" when setting the speed although I do not use
119 it for anything.
120A. If you do not use cdparanoia, eject is used for setting the speed of the
121 cdrom drive. You can substitute it for "setcd" with "-x" as the argument,
122 but you have to install it manually (setcd is, at least, available in
123 Debian).
124 Another way to get the same results is using the pre_read function, defined
125 in your /etc/abcde.conf file.
c9c2ca27 126
b7f1cc84 127Q. I have a CD set with 1+ discs, and want to have them in the same directory,
128 sorted properly. What can abcde do for me?
129A. Set abcde to rip the first CD and give it the option "-t 101". Use a generic
130 name for the CD, and reuse it with the rest of the CDs, editing the CDDB
131 entries. Use "-t 201" for the second CD and so on. Use "-w <comment>" to
132 add a comment about the CD you are ripping (-w "disc #"). Alternatively you
133 can use only the "-t ###" option and then move all the files to the same
fd34b28b 134 directory, but the tag/comment information on the files will differ. If you
135 want the tagged track number to be set to the modified number you should use
136 "-T ###".
137 Even better! If you use "-W <cd_number>", abcde will put a comment to every
138 CD set ("CD <number>") and modify the number of the tracks both in the file
139 name and the tag/comment information.
b7f1cc84 140
141Q. I have a live concert. I want to encode it in a single file. How do i do it?
fd34b28b 142A. Use "-1" and it will be encoded in a single file. Use "-M" to make a CUE
143 sheet file where the information about the tracks is stored.
b7f1cc84 144
1453. CDDB
146 ====
148Q. I need to go through an HTTP proxy for CDDB access.
149A. No problem, just export your http_proxy variable first so wget/fetch/curl
150 can see it.
152Q. I already store CDDB entries in my hard disc. Can I make use of them?
153A. Piece of cake. Just edit CDDBLOCALDIR to point to the repository and give
154 abcde the "-L" flag to make use of it.
156Q. Fine, now it uses local CDDB, but I have no network connection. How can I
157 disable CDDB checks?
158A. Use the "-L -n" combination. It will try to use local CDDB entries, and if
159 nothing can be found, it will use a template. You will be also given the
160 choice to edit such template.
162Q. How can I use some other CDDB information provider?
163A. abcde now uses FreeDB by default. To use a different FreeDB mirror or
164 another CDDB service, change the CDDBURL option in your abcde.conf.
168 =======
170Q. What formats can I encode my music to?
171A. As for version 2.2, abcde includes support for MP3, Ogg/Vorbis,
172 Ogg/Speex, Flac and MPP/MP+(Musepack). Support for AAC will be added once
173 an FLOSS encoder/decoder is working.
175Q. I want the new *put the newest and coolest codec there* format to be
176 supported by abcde. Abcde is so cool but i want to encode also to this
177 new format...
178A. Patches are welcome! ;)
179 No, seriously, if the format is usable, available for Linux and open
180 source/free software, it should be fairly easy to integrate. Support for
181 AAC (m4p) should be the next one to be introduced.
c9c2ca27 182
183Q. I use Debian/RedHat/(put your Unix flavour here) and MP3 encoding is not
184 working. What am I doing wrong?
185A. Since MP3 is considered non-free (you get it for free, but hardware players
186 and net broadcasters have to pay license fees), some release engineering
187 groups and release management teams have decided not to provide MP3 encoding
188 tools.
189 These distributions or operative systems have decided to use Ogg/Vorbis as
190 the default encoding format, since it contains no (known) patent claims
191 and they are (supposed to be) completely Free (released under a BSD-like
192 license).
193 However, there is no strong (at the moment) hardware support, although
194 some groups and companies are strongly working on getting it, real soon
195 now. For that reason some people prefer to encode to MP3.
fd34b28b 198 There are known brands already selling Ogg/Vorbis portable players: Rio,
199 iRiver, Neuros, iAudio,...
c9c2ca27 200 Go buy one and you have no more reasons to use MP3.
202 If you are among those individuals, you might need to add support for MP3
203 encoding to your system:
f97e22a3 204 Debian : check to install lame in your
205 system. Others prefer bladeenc. Check or google.
c9c2ca27 206 RedHat : search on
207 FreeBSD: By default includes LAME support.
208 OpenBSD: Available by specifying you want to install the port with LAME
209 support, or by just installing it later from the ports tree.
210 NetBSD : Available in pkgsrc.
212 Others : Please, help me here.
b7f1cc84 214Q. Huh! Why is MPPENCODER (with MPP) and .mpc the extension?
215A. Dunno. You must ask the guys who created and defined the format. The
216 standard is MPEGplus (MPP/MP+) but the files use .mpc extension.

220 ==== ========
79e3928b 221
b7f1cc84 222Q. What happened with normalize?
223A. Normalize has changed its name under Debian, which is the GNU/Linux
224 distribution for developing abcde (well, is The GNU/Linux Distribution
225 i only use, at the moment). Now it is called normalize-audio.
226 If you are using some other flavour of OS, you need to change the name
227 of the executable in your abcde.conf file.
79e3928b 228
b7f1cc84 229Q. I am using MacOSX and I am having problems to use abcde.
230A. Well, I have a Mac, but I use linux on it. I have not been able to find
231 a way to make it work there, since I do not have the development tools
232 installed. I have placed a basic support, but some user reports are just
233 complaining about abcde not encoding the ripped tracks, as if
234 cdda2wav/cdparanoia/cddafs would never end reading them. If you have such
235 a system and experience problems, please, report them, and I will try to
236 work them out with your help.
c9c2ca27 237
238Q. My hardware player (put it here) does not recognize the playlists created
239 with abcde. What I am doing wrong?
240A. Try using "-m" when creating the playlists, or setting DOSPLAYLIST as an
241 option in the config file.
c9c2ca27 243OBSOLETE
245Q. I set KEEPWAVS to "y" but abcde insists on erasing my directory, along
246 with the wav tracks. What I am doing wrong?
247A. The default action set includes clean, which cleans the temp directory,
248 if nothing goes wrong. Take the "clean" out from the action list and you
249 are done.
250 UPDATE: KEEPWAVS unselects now the clean action.
