Free audio convtools software for linux

Audio::ConvTools is a API to convert audio files from/to mp3 ogg and wav.

SYNOPSIS

use Audio::ConvTools;
use Audio::ConvTools qw/:DEFAULT :Tmp :Log/;

$status = ogg2mp3(file.ogg);
$status = ogg2wav(file.ogg);
$status = ogg2wav(in.ogg, out.wav);
$status = mp32ogg(file.mp3);
$status = mp32wav(file.mp3);
$status = mp32wav(in.mp3, out.wav);
$status = wav2ogg(file.wav);
$status = wav2ogg(in.wav, out.ogg);
$status = wav2mp3(file.wav);
$status = wav2mp3(in.wav, out.mp3);

Audio::ConvTools::logMsg(This is a log message);
Audio::ConvTools::errMsg(This is an error message);

$tmp = Audio::ConvTools::getTmpFile(.wav);
Audio::ConvTools::destroyTmpFile($tmp);

Python Audio Tools are a collection of audio handling programs which work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more.
Supports internationalized track filenames and metadata using Unicode. Works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from FreeDB or FreeDB-compatible servers. Audio formats supported are:
- WAV
- AIFF
- Sun AU
- FLAC
- WavPack
- Monkeys Audio
- MP3
- MP2
- Ogg Vorbis
- Ogg Speex
- M4A
Easy to install and use:
I dont like programs with lots of obscure dependencies, so Ive written Python Audio Tools to require as few external libraries and programs as possible. Most formats require only one or two common executables and some require none at all. Installation utilizes Pythons built-in distutils, but a provided makefile reduces the process to a simple "make install" command.
The programs that make up Python Audio Tools provide a consistent interface for painless switching between them. man pages are included, as is a lengthy manual for both users and programmers. See the short tutorial in the documentation for an illustration of their usage.
These Python Audio Tools are designed with Unix-like systems in mind. Although most of it is written in pure Python, the libcdio library is used to read from a CD-ROM drive. If one is willing to forgo the CD-based tools, Python Audio Tools is fully portable so long as the required helper applications are present. I have used it on the i386, x86_64 and ppc architectures without difficulty.
Standards compliant
Because Python Audio Tools sticks very close to established, documented standards, it has no trouble interoperating with other audio-handling programs. If you want to rip CDs with Exact Audio Copy, batch convert them to M4As with these tools and play them back in iTunes, thats no problem.
Enhancements:
- Revamped the track metadata system.
- Improved the file detection routines.
- Minor bugfixes.

Audio Daemon is a perl module to daemonize various players and support a single UDP interace for different players. Currently you can set up a server for MPG123, Xmms and an icecast stream (using libshout).

Audio::Daemon is made of two parts, the client and server.

The Client (Audio::Daemon::Client) remains the same across the board no matter what server you are communicating with, with a few exceptions noted in the pods.

The Server currently can be configured to be MPG123, Xmms or an Icecast (libshout) stream. Neither the Client nor the Servers need to be run as root and I strongly advise against it.

Audio::Daemon::MPG132:
Requires Audio::Play::MPG123 an optionally Audio::Mixer for volume control. It automatically spawns mpg123 in the background so there is no need to prestart it.

Audio::Daemon::Xmms:
Requires the Xmms and MP3::Info perl module and xmms installed. Id suggest getting the latest version of the Xmms perl module. It uses the volume and random feature built into xmms and if it doesnt find an xmms running it will try to spawn its own copy. Bear in mind that
xmms MUST HAVE an X display to export to, and that xmms must be running as the same user Audio::Daemon::Xmms is.

Audio::Daemon::Shout:
This wasnt easy to do. It requires MP3::Info and libshout to be installed (http://developer.icecast.org/libshout/) as well as a functioning icecast server. The timing here is pretty critical so I recomend being careful not to be polling the server too much. Be sure to read the icecast docs as Im still confused on how I got this part to work.

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.

JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apples OS X.

Jack audio connection kit can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.

Audio::OSS is a pure-perl interface to OSS (open sound system) audio devices.

SYNOPSIS

use Audio::OSS qw(:funcs :formats :mixer);

my $dsp = IO::Handle->new(" dsp_reset($dsp) or die "reset failed: $!";

my $mask = get_supported_formats($dsp);
if ($mask & AFMT_S16_LE) {
set_fmt($dsp, AFMT_S16_LE) or die set format failed: $!";
}
my $current_format = set_fmt($dsp, AFMT_QUERY);

my $sps_actual = set_sps($dsp, 16000);

set_fragment($dsp, $fragshift, $nfrags);
my ($frags_avail, $frags_total, $fragsize, $bytes_avail)
= get_outbuf_info($dsp);
my ($bytes, $blocks, $dma_ptr) = get_outbuf_ptr($dsp);

my $mixer = IO::Handle->new(" my $miclevel = mixer_read($mixer, SOUND_MIXER_MIC);

Audio::OSS is a pure Perl interface to the Open Sound System, as used on Linux, FreeBSD, and other Unix systems.

It provides a procedural interface based around filehandles opened on the audio device (usually /dev/dsp* for PCM audio).

It also defines constants for various ioctl calls and other things based on the OSS system header files, so you dont have to rely on .ph files that may or may be correct or even present on your system.

Currently, only the PCM audio input and output functions are supported. Mixer support is likely in the future, sequencer support less likely.

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.
