Free digital audio extraction software for linux

Digital Room Correction project is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation.
DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesnt provide convolution features, and provides only some simplified, although really accurate, measuring tools.
For further informations see the documentation section, which includes the full manual of the current version of DRC and a complete set of measurements showing the effect of the DRC correction in a real life situation.
DRC is available for free and is released under the terms of the GNU General Public License. See the documentation for details.
Enhancements:
- A new feature for replacing command line parameters has been introduced.
- The dip and peak limiting procedures have been improved in order to avoid numerical instabilities.
- A new wavelet-based analysis graph has been added to the sample results.
- Many performance improvements have been introduced.
- A new optional parameter used to define the base directory for all files has been added.

Digital Camera Protocol is another command-line utility for DC21x cameras, this one looks and works just like "ftp" command. Not written by me, but uses some of my low-level Kodak code from digicam.

RJBs Digital Media Center is a music player.
RJBs Digital Music Center is designed to run on dedicated hardware. Because of this. It running as root. Very dangerous. Other than grabbing the X display and calling stop and halt scripts. It should be able to run as a non-root user. I will look into this on future releases.
Install steps:
(1) Install Nvidia Graphics Card.
(2) Plug X10 or IRMan control module into Com1.
(3) Connect Computer to Television
(4) Install RedHat 9.0
(5) During RedHat install select "Server Install"
(5) During package selection
(a) Select The Following Packages
X Window System
Sound and Video
Windows File Server
Development Tools
X Software Development
(b) De-Select The Following Packages
Printing Support
Text Based internet
Server Configuration Tools
Web Server
Administration Tools
(6) Identify or Create a directory for your Media files.
mkdir /usr/local/Media
Would be a good choice. The install script will ask and expect this path to exist. It will create a symbolic link to it. Also create symbolic link inside to for Cdrom to /mnt/cdrom
(7) As root UnZip/Tar the DMC release in /usr/local
cd /usr/local
tar zxvf dmc-releaseV2.0.tgz.tgz
(8) If your System is a HP DEC then you need to copy from the original HP disk the binary decvfdcmd.
cp /opt/odin/dec/bin/decvfdcmd /tmp
This binary controls the front LCD display.
The install script will ask for this path.
(9) As root run the DMC Install Script.
cd /usr/local/dmc/bin
./Install.sh
(10) Answer questions and follow instructions
(11) Good Luck!

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.

Make audio is a graphical tool to create audio CDs from MP3 or wav files. You can simply arrange a playlist of all songs that you want. The application converts MP3 files to WAV and then burns them on the CD.

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::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.
