You can now populate the Thundaural jukebox database with audio tracks from
your own personal collection rather than having to rip physical CDs.
For each album, the process is three steps:
1. clean up the metadata on your audio files and acquire a cover art image.
The Thundaural jukebox interface is highly interactive, so having
accurate metadata and good information about the tracks will make it
easier for users to find them. You have two options:
- this could be as simple as renaming all the files and arranging them
in subdirectories by album. The filenames should include the
artist/performer, the album name, the track number and the song
title.
- a more involved, but possibly more accurate method, is to set the
audio file tags (id3v1, id3v2, ogg comments) to the necessarily
information. You can use a program like the MusicBrainz Tagger
(www.musicbrainz.org unfortunately only runs on Windows or OSX) or
some other automated tagging application. I'm sure there are a
number of them listed on freshmeat.net. Often times, audio files
you purchase on-line will already have accurate metadata tags,
although you may need to convert from the lame propritary lock-in
formats like AAC (iTunes Music Store) to a format that Thundaural
can play (MP3 or Vorbis). Hopefully, that conversion process will
copy any tags to the new file. Actually setting the tags is beyond
the scope of this document and this utility.
this is, most likely, the most involved step.
2. use the tapersonalarchive script to generate a
Thundaural-specific metadata file for each album. In most cases, this is
simply a matter of giving this script the directory that contains the
tracks. It will generate a .pv file.
3. feed the .pv file to the taripdisc script, which will populate
the database and copy the audio files and cover art to the correct place
so the Thundaural jukebox server can access them.
Let's go over an example. I recently downloaded the "Kong in Concert: Donkey
Kong Country Arrangement Collaboration" from http://dkcproject.ocremix.org. I
want to add these tracks to my jukebox. I made a directory (~/kongalbum) to
store all the tracks in this new album and put the files in it (I had
previously converted the files from .wav to Ogg Vorbis before starting this):
Kong in Concert - 01 - Israfel - Godiva in the Desert (Theme).ogg
Kong in Concert - 02 - Hemophiliac - Swing, Monkey, Swing (Simian Segue).ogg
Kong in Concert - 03 - JigginJonT - West Coast DK Island (DK Island Swing).ogg
Kong in Concert - 04 - Unknown - Rest and (Re)spite on a Soft Summer Night (Cranky's Theme).ogg
Kong in Concert - 05 - Adhesive_Boy - Cry of the Chasmal Critter Chain (Cave Dweller Concert).ogg
Kong in Concert - 06 - Icy Guy - One Zero One (Bonus Room Blitz).ogg
Kong in Concert - 07 - Vigilante - Beneath the Surface (Aquatic Ambiance).ogg
Kong in Concert - 08 - Vigilante - Funky Monkey Love (Candy's Love Song).ogg
Kong in Concert - 09 - Red Omen, Protricity - Boiling Point (Bad Boss Boogie).ogg
Kong in Concert - 10 - Protricity - Mine Cart Misadventure (Mine Cart Madness).ogg
Kong in Concert - 11 - Sadorf, Sir NutS - Echoes (Life in the Mines).ogg
Kong in Concert - 12 - GrayLightning - Idols of Hanuman (Voices of the Temple).ogg
Kong in Concert - 13 - zircon - Faunaphonic (Forest Frenzy).ogg

Kong in Concert - 17 - Prophecy - Chekan Winter (Northern Hemispheres).ogg
Kong in Concert - 18 - analoq - dolilop do wop (Ice Cave Chant).ogg
Kong in Concert - 19 - GrayLightning - Machina Anesthesia (Fear Factory).ogg
Kong in Concert - 20 - Dhsu - Pirate Prelude (Gang-Plank Galleon Pt 1).ogg
Kong in Concert - 21 - SnappleMan - Thrash the Plank (Gang-Plank Galleon Pt 2).ogg
Kong in Concert - 22 - Protricity - Rare Reminiscence (The Credits Concerto).ogg
Twenty-two tracks. Note that even though the download of this album is
arranged in such a way as to suggest it is two physical CDs, I wanted to have
all the tracks appear on one album in my jukebox. So I just put all the files
in the same directory. You do not need to arrange all the albums in your
jukebox the same way the music comes off a physical CD; you can mix and match
tracks from different albums how ever you like. But keep in mind that
Thundaural jukebox is designed to work similar to a real jukebox, and mixing
and matching tracks from different albums will make it difficult to
find/create appropriate cover art, and can make it difficult for people to
find certain tracks when browsing. I would suggest against making playlists
using the album metaphor in this case. Album arrangment of tracks will make
it easy to find tracks within the system. Order of play is outside of that,
and can be chosen via the interface (just like a regular jukebox).
There are multiple images that can be used to make the jewel case jacket and
inserts for "Kong in Concert", and Thundaural can use more than one image, but
I just picked a single image (from their download collection). Put this image
in the same directory with the tracks and name it coverart.ext. It can be a
JPEG, GIF or PNG image, so ext may vary. The basename of the file should be
"coverart" though, so the script can find it easily.
coverart.png
So now the directory for this example contains 23 files. 22 tracks and 1
image.
Now, I run the tapersonalarchive script and give it the name of
directory that contains the tracks:
./tapersonalarchive --metadata filename \
~/kongalbum \
--pattern '^(.+) - (\d+) - (.+) - (.+).ogg$' \
--matchorder album,tracknum,artist,title
This says to use the filename to find metadata, the filename should match the
specified regular expression and the parenethesied sub-expressions of the
regular expression give the values for, in order, the album name, the
tracknumber, the artist and the track title. For these "Kong in Concert"
tracks, I needed to specify pattern and match order because the format of the
filenames is different than the default (see the --help option for the
default).
The regular expression must start and end with the anchors ^ and $.
In some cases, the album or artist name may be part of the parent directory
structure. In that case, use --fullpath to have the regular expression
applied to the full path of the file (as given relative to the path specified
on the command line). For example, if you have a directory structure like:
The Beatles
Revolver
01 Taxman.mp3
02 Eleanor Rigby.mp3
03 I'm Only Sleeping.mpg
04 Love You To.mp3
...
and thus one of the filenames, with path, is:
~/music/The Beatles/Revolver/03 Eleanor Rigby.mp3
Then specify --fullpath and
--patern '^.+/([^/]+)/([^/]+)/(\d\d) (.+).mp3$'
^^^^^ ^^^^^ ^^^^ ^^
(I've used carets to point out each sub-expression) and for match order,
give it:
--matchorder artist,album,tracknum,title
The regular expression can be as complex as you like. If a subexpression
shouldn't match any of the four fields listed above, you should specify
"undef" in the position of that subexpression.
If you use the "--metadata tags" option, --pattern and --matchorder isn't
necessary, as the fields will be attempted to be read from the tags in the
files.
So the tapersonalarchive script created a .pv file in the ~/kongalbum
directory. You should look over this file to make sure everything checks out.
You can make changes, but it might be good if you knew perl syntax so the file
is readable. If
If you had elected to
Note that if you run tapersonalarchive multiple times and it finds
different metadata, you might end up with multiple files because the filename
contains the artist and album name it found.
You can now feed the .pv file to the taripdisc script, to get the files
copied to the correct place and the database to be loaded. Usually this
script is invoked by the server to rip a physical CD, but in this case we'll
invoke it ourselves on the command line:
./taripdisc --infofile X.pv --storagedir SD --dbfile DBF
where:
X.pv is the file written by the tapersonalarchive script
SD is the storage directory (usually /home/storage)
DBF is the path to the database file (usually /home/storage/db/data.db)
The taripdisc script currently does not read the thundural-server.conf file
for these values (that'll be in an upcoming version) so you'll need to specify
them yourself.
It should dump a bunch of stuff out and populate the database.
And that's it. These tracks should now be accessible from the server (and
thus from the client) and be available for playing.
If no coverart file is found in the album directory, it will not add coverart
to the database. In this case, you can use the album-images.pl script to
manlipulate cover art once the tracks are loaded.
