Icecast is a MP3 and OGG streaming server able to serve many clients
with MP3 and OGG audio.

IceS is a source client for a streaming server. The purpose of this
client is to provide an audio stream to a streaming server such that
one or more listeners can access the stream. With this layout, this
source client can be situated remotely from the icecast server.

JACK is system for handling real-time, low latency audio
(and MIDI). It runs on GNU/Linux, Solaris, FreeBSD, OS X and
Windows (and can be ported to other POSIX-conformant
platforms). It 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 also
has support for distributing audio processing across a
network, both fast & reliable LANs as well as slower, less
reliable WANs.

JACK Rack is a stereo LADSPA effects rack for the JACK audio API. You
can insert LADSPA effects through JACK Rack. It uses GTK+ 2 for the
GUI.

jackEQ is a tool for routing and manipulating audio from and to
multiple input/output sources. It runs in the JACK Audio Connection
Kit and uses LADSPA for its back-end DSP work. jackEQ is designed
specifically for live performance.

JAMin is the JACK Audio Connection Kit (JACK) audio mastering
interface. JAMin is designed to perform professional audio mastering
of stereo input streams. It uses LADSPA for digital signal processing
(DSP).

The Linux Audio Developer's Simple Plug-in API (LADSPA) provides the
ability to write simple plug-in audio processors in C/C++ and link them
dynamically. The package contains the LADSPA SDK, the CMT plug-in
libraries (including Freeverb), and the swh plug-ins.

This package contains include files to develop LADSPA plugins.

LASH (formerly LADCCA) is a session management system for JACK and ALSA
audio applications on GNU/Linux. Its aim is to allow you to have many
different audio programs running at once and to save the setup, close
them down, then reload the setup at some other time.

Libao is a cross-platform audio output library. It currently supports
ESD, OSS, Solaris, and IRIX.

Capabilities are a measure to limit the omnipotence of the superuser.
Currently a program started by root or setuid root has the power to do
anything. Capabilities (Linux-Privs) provide a more fine-grained access
control. Without kernel patches, you can use this library to drop
capabilities within setuid binaries. If you use patches, this can be
done automatically by the kernel.

This package provides a compatible library for the old libcap-1.

libid3tag is a library for reading and writing ID3 tags, both ID3v1 and
the various versions of ID3v2.

Libjackasyn is a library that allows you to run any Linux sound program
made for the OSS system as a JACK client.

This is a lightweight, easy-to-use implementation of the OSC protocol
(see http://www.cnmat.berkeley.edu/OpenSoundControl/ for details).

This is a library to make it easy to manipulate RDF files describing
LADSPA plug-ins. It can also be used for general RDF manipulation.

It can read RDF, XLM, and N3 files and export N3 files. Ot also has a
light taxonomic inference capability.

Libogg is a library for manipulating ogg bitstreams. It handles both
making ogg bitstreams and getting packets from ogg bitstreams.

Ogg is the native bitstream format of the libvorbis (Ogg Vorbis audio
codec ) and the libtheora (Theora video codec)

liboggz is a library that provides simple parsing and seeking of
files and streams based on the Ogg file format. liboggz requires
libogg to work.
liboggz knows about Ogg speex, Ogg vorbis, Ogg theora, and the Ogg
based Annodex formats, thus allows parsing (though not decoding) of
these files.

Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for
audio. One example of where such a thing would be useful is in
converting audio from the CD sample rate of 44.1kHz to the 48kHz sample
rate used by DAT players.

SRC is capable of arbitrary and time varying conversions; from
downsampling by a factor of 12 to upsampling by the same factor. The
conversion ratio can also vary with time for speeding up and slowing
down effects.

Libshout is a library for communicating with and sending data to an
icecast server. It handles the socket connection, the timing of the
data, and prevents bad data from getting to the icecast server.

Libsndfile is a C library for reading and writing sound files, such as
AIFF, AU, and WAV files, through one standard interface. It can
currently read and write 8, 16, 24, and 32-bit PCM files as well as
32-bit floating point WAV files and a number of compressed formats.

This package includes the example programs for libsndfile.

Vorbis is a fully open, nonproprietary, patent-and-royalty-free, and
general-purpose compressed audio format for audio and music at fixed
and variable bit rates from 16 to 128 kbps/channel.

The native bitstream format of Vorbis is libogg (Ogg). Alternatively,
libmatroska (matroska) can also be used.

Linkloop is similar to ping, but tests the network connectivity at the
link layer (layer 2) instead of the network layer (layer 3).

Mercurial is a fast, lightweight source control management system
designed for efficient handling of very large distributed projects.
