Free audio software for linux

Perl Audio Converter (PAC) is a tool for converting multiple audio types from one format to another. It supports MP2, MP3, Ogg Vorbis, FLAC, Shorten, Monkey Audio, FAAC (AAC/M4A/MP4), Musepack (MPC), Wavpack (WV), OptimFrog (OFR/OFS), TTA, LPAC, Kexis (KXS), AIFF, AC3, Lossless Audio (LA), AU, SND, RAW, VOC, SMP, RealAudio (RA/RAM), WAV, and WMA.
It can also convert audio from the following video formats/extensions: RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, QT, VCD, VOB, and WMV. A CD ripping function with CDDB support, batch and playlist conversion, tag preservation for most supported formats, independent tag reading/writing, and extensions for Konqueror and amaroK is also provided.
Enhancements:
- Added: MP4::Info dependency IO::String to pacpl-install
- Updated: License GPLv3
- Bug Fix: Directory conversions. pacpl was claiming the directory was empty and prompting to use the --recursive option...Thanks to John Meyer for the report.

MPEG Audio/Video Player is a simple MPEG and AC3 player for Linux, BSD, and Windows systems.
It plays MPEG transport, program, and elementary stream files. It also has basic DVD support (using libdvdnav on Linux/BSD sytems only).
Main features:
- Runs on Windows, Linux, and BSD systems.
- Plays MPEG Transport Stream, Program Stream, and Elementary Stream files.
- Basic DVD support (with libdvdnav on Linux/BSD systems only).
- Decodes MPEG 1&2 Video, MPEG Layer 2 Audio, and AC3 audio.
- All decoders use only integer operations, for faster performance.
- Flexible, and easy to use decoders, that can decode streams in chunks as small as 1 byte (buffering is not necessary).

CrystalAudio is a FVWM-Crystal configuration tuned for use on an audio workstation. It has many new applications for the menu, including many sound-related applications and improved sound controls. The project launches qjackctl at startup.
The final goal of the project is to make the FVWM-Crystal menu compatible with the freedesktop specification and to provide some tools to generate the menu entries and icons from desktop and icon files provided by the applications in the system.
Enhancements:
- generate-fvwm-crystal-menu work with both new and old type application desktop files, so it is time for the 2.0 version.
- A lot of debugging have been done on that script: See the ChangeLog for the details.
- Added support for stalonetray in all the recipes.

Audio::Moosic is a Moosic client library for Perl.

SYNOPSIS

use Audio::Moosic;

$moo = Audio::Moosic::Unix->new();

$moosic->append(/home/me/somewhat.ogg);
$moosic->play;
print $moosic->current, "n";
$moosic->pause;
...

Audio::Moosic acts as a client for the musical jukebox programm Moosic (http://nanoo.org/~daniel/moosic/) by Daniel Pearson.

Using Audio::Moosic you can connect to a moosic server either via an UNIX socket or an INET socket.

Audio::Daemon::MPG321 is a song queue daemon for Audio::Play::MPG321.

SYNOPSIS

use Audio::Daemon::MPG321; my $player = new Audio::Daemon::MPG321 ("/home/dabreegster/foo.mp3", "/home/dabreegster/bar.mp3");
$SIG{CHLD} = IGNORE; $player->add("/home/dabreegster/blah.mp3");
while (1) { until ($player->{player}->state() == 0) { $player->{player}->poll(); select(undef, undef, undef, 1.0); } $player->{pointer}++; unless ($player->{queue}->[$player->{pointer}]) { exit 0; } else { $player->load(); } }

This daemonizes Audio::Play::MPG321, or at least gives it the ability to manage a song queue. You can build a simple queue of songs and move between them.
Note the infinite loop in the synopsis. You must put this in your program or the queue wont work!

All it does is keep Audio::Play::MPG321s knowledge of the state of the player fresh and continously tests to see if one song is over so the next can be loaded. The code is kept out of the module itself because this process must be done, one way or the other, and forking in the module itself is very messy.

The example loop will work fine and you may modify it any way you like to incoorporate it into your frontend, as long as you poll the player, test to see if the song is finished yet, and load the next song in the queue (If there is one!) when it is time to do so.

Audio::XMMSClient is a Perl interface to the xmms2 music player.

SYNOPSIS

use Audio::XMMSClient;

$c = Audio::XMMSClient->new( $name );
$c->connect;

my $r = $c->playback_status;
$r->wait;
print $r->value;

This module provides a perl interface to the xmms2 client library. It currently lacks a good documentation, but the turorial directory provides some nice and well explained examples to get you started for now.

Audio::Beep::Linux::PP is a PurePerl implementation of an Audio::Beep player.

SYNOPSIS

my $player = Audio::Beep::Linux::PP->new();

USAGE

The new class method will return you a new player object. No other option is available right now.

NOTES

You need to be root to play something using this module. Otherwise your script should be SUID root (but i wont suggest that). Or you could own the tty where you execute this, but it cannot be an xterm. Its better to install the beep program by Johnathan Nightingale and then SUID that small program.

This module is just a rewriting of the core function of the beep program. I took everything from there so credit goes again to Johnathan Nightingale. As this is a PurePerl module i had to do some assumption, like the KIOCSOUND constant to be 0x4B2F (which may not be your case). The CLOCK_TICK_RATE is also taken from beep.

Audio::MadJACK is a Perl module to talk to MadJACK server using Object Oriented Perl.

SYNOPSIS

use Audio::MadJACK;

my $mj = new Audio::MadJACK( osc.udp://madjack.example.net:4444/ );
$mj->load( Playlist_A/mymusic.mp3 );
$mj->play();

The Audio::MadJACK module uses Net::LibLO to talk to a MadJACK (MPEG Audio Deck) server. It has an Object Oriented style API making it simple to control multiple decks from a single script.

new( oscurl )

Connect to MadJACK deck specified by oscurl. A ping is sent to the MadJACK deck to check to see if it is there. If a reply is not recieved or there was an error then undef is returned.

load( filepath )

Send a message to the deck requesting that filepath is loaded. Note: it is up to the developer to check to see if the file was successfully loaded, by calling the get_state() method.

Returns 1 if command was successfully received or 0 on error.

play()

Tell the deck to start playing the current track.

Returns 1 if command was successfully received or 0 on error.

pause()

Tell the deck to pause the current track.

Returns 1 if command was successfully received or 0 on error.

stop()

Tell the deck to stop decoding and playback of the current track.

Returns 1 if command was successfully received or 0 on error.

cue( [$cuepoint] )

Tell the deck to start decoding from $cuepoint, which is the position in the track in seconds. If no $cuepoint is specified, the the deck will start decoding from the start of the track.

Returns 1 if command was successfully received or 0 on error.

eject()

Close the currect track loaded.

Returns 1 if command was successfully received or 0 on error.

get_state()

Returns the current state of the MadJACK deck. Returns one of the following strings:

- PLAYING
- PAUSED
- READY
- LOADING
- STOPPED
- EMPTY
- ERROR

If no reply if received from the server or there is an error then undef is returned.

get_error()

Returns the a string describing the current error (if state is ERROR).

get_version()

Returns the version number of the MadJACK server.

get_duration()

Returns the durtion (in seconds) of the current track.

If no reply if received from the server or there is an error then undef is returned.

get_position()

Returns the decks position (in seconds) in the current track.

If no reply if received from the server or there is an error then undef is returned.

get_filepath()

Returns the file path of the track currently loaded in the deck (path will be in the same form as originally passed to load()).

If no track is currently loaded then an empty string is returned. If no reply if received from the server or there is an error then undef is returned.

ping()

Pings the remote deck to see if it is there.

Returns 1 if the server responds, or 0 if there is no reply.

get_url()

Returns the OSC URL of the MadJACK deck.
