The Sajber Jukebox is a mpeg layer 3 player with a graphical user interface. Its based on Woo-jae Jungs splay for the audio and has a QT based graphical library for the interface.
Main features:
- Supports mpeg layer 3. The support for mpeg layer 1 & 2 and wav files is still in there, but untested.
- Playing of the net. By using normal http addresses, ie http://whatever.host.on.the.net/~someguy/song.mp3, you can play without having to first download.
- Forward, Rewind, Pause, Seek. The Sajber Jukebox allows for moving backwards and forwards in the song [unless its streaming, then rewind wont work]. By pressing on the progression bar you can make swift jumps to any place in the song of your liking.
- Mixer control. The Sajber Jukebox comes with a mixer control that allows you to change bass, treble, volume and pcm/dsp setting at any time without having to start a second program.
- Three types of browsers:
- File Browser. A local filemanager type of browser, which allows you to click around on your local system and select songs you wish to play.
- Standard Database. A database which allows you to recursively scan the harddisk or a directory structure in search for songs. The database is sorted by group, album and songname and makes it easy to keep track of your songs, unregardless of where on the harddisk they are located. It also supports http references in addition to ordinary files.
- Http Browser. This browser allows for playing songs of the net, and scanning home pages for songs. By giving the Http Browser an URL to a page, it will retrieve it and search it through for any references to playable files.
- Selections. You can select songs from any number of browsers, and play them with repeat and random.
- Configurability. The Sajber Jukebox is easy to configure, and provides a graphical interface instead of having to figure out how various options in the obscure rc files works.
- Saving. Selections, Standard Databases, Http Browsers and configurations can be saved to disk for easy retrieval, or autoloading at startup.
- Realtime threads. If youre a daredevil who believes that everything else on your machine oughta come second to the playing of audio, you can configure your player to use realtime scheduling.
- Bookmarks. You can save and edit bookmarks to various http or local locations for swift jumps around the filesystem or the world.
- Progression bar and timer to keep track of where in the song you are.
- Easily change between different databases and browsers.
- A smaller Players window, with the basic functions which wont cover the entire screen.

Audio::Ao is a Perl wrapper for the Ao audio library.

SYNOPSIS

use Audio::Ao qw(:all);

initialize_ao;
my $device = open_live(default_driver_id(), 16, $rate, $channels,
is_big_endian(), {});
while (#have data) {
play($device, $data_buffer, $len_of_buffer);
}
close_ao($device($device));
shutdown_ao;

Provides access to Libao, "a cross-platform library that allows programs to output PCM audio data to the native audio devices on a wide variety of platforms." Libao currently supports OSS, ESD, ALSA, Sun audio, and aRts.

MDF audio extracter project is a tool to extract audio data from MDF/MDS audio cd images to wav or raw files. Tracks will be extracted to the current directory and named track_[num].wav or track_[num].raw. Output can also be redirected to stdout to allow the audio data to be fed to an encoder or player directly.
You need both a .mds and .mdf file to be able to extract tracks. The .mds file contains the information about the tracks, while the .mdf file contains the actual data. They usually should have the same name (except for the extension ofcourse). This is case sensitive, so for example FileName is not the same as filename.
Usage: mdfextract [options] file.mds
Options:
-i output mds info instead of extracting
-r extract raw track data
-s output to stdout instead of file
-t < num > extract single track (num > 0)
-q quiet, no output
Version restrictions:
- Probably does not work on big endian archs.

jukebox-control project is a complete automation for Sony A/V components featuring S-Link (CD, DVD, MD, etc).
jukebox-control includes a Linux driver module for an easy/dirty cheap to build DIY parallel to the Sony S-Link interface, plus Perl modules with both control-A1 (II) and control-S protocol implementations.
Its actually-incomplete development state makes it interesting for developers mostly.
Enhancements:
- Bidirectional Control-A1 protocol fully supported
- Unidirectional Control-S protocol implemented, not fully supported yet.
- New object model that ties A1 and S devices together under the same base class.
- CDDB support has been removed temporarily. I am rewriting most of the modules at this time.
- No real user interface. Hey! This is a interim release.

The Polar Jukebox System (PJS) is a set of curses and console applications that allow you to manage huge amounts of MP3 files. It stores all information in a PostgreSQL database for fast and reliable acces.
The reason I started this project is that I always wanted a easy-to-use music collection, and I reached that goal with the PJS. I started programming in late 1998 and kept programming from time to time. Now I think the PJS is ready for the public, even not everything that is possible has been done - but it works!
The PJS runs under the GPL (GNU Public License) an can be installed on computers running Debian GNU/Linux, other distributions are not supported till now, and I still need help for packing the PJS to others dists.
Main features:
- Riping/encoding of audio CDs (with CDDB support) into the PJS with jrec
- Easy management of a big CD Collections with jplay
- Playlistgeneration and -management
- Automatic playlists (alltime charts, newcomers, rarely played...)
- Special play modes (random, linear...)
- Export of CDs to CD-R
- Database (postgresql) storage of the track and CD information

Audio::M4P is a Perl module that provides M4P/MP4/M4A QuickTime audio music format modules.

M4P is a QuickTime protected audio file format.

SYNOPSIS

use Audio::M4P::QuickTime;

my $mp4file = "file.m4p";
my $qt = new Audio::M4P::QuickTime(file => $mp4file);
my $tags = $qt->GetMetaInfo;
print "Artist is $tags->{ARTIST}n" if $tags->{ARTIST};


use Audio::M4P::Decrypt;

my $outfile = mydecodedfile;
my $deDRMS = new Audio::M4P::Decrypt;
$deDRMS->DeDRMS($mp4file, $outfile);
