FLAC is an open source lossless audio codec developed by Josh Coalson.

FluidSynth (formerly IIWU Synth) is based on the SoundFont(tm) 2
specifications. It is a real-time "software synthesizer". FluidSynth
can read MIDI events from the MIDI input device and render them to the
audio device. It can also play MIDI files.

FluidSynth-DSSI is the plug-in implementation of fluidsynth on DSSI
(Disposable Soft Synth Interface) with a GTK+ GUI.

FreqTweak is a tool for real-time audio spectral manipulation and
display. It provides several algorithms for processing audio data in
the frequency domain and a highly interactive GUI to manipulate the
associated filters for each algorithm. It also provides high-resolution
spectral displays in the form of scrolling-raster spectrograms and
energy versus frequency plots displaying both preprocessed and
post-processed spectra.

A graphical mixer program for ALSA. Its GUI is based on GTK+.

Gnash is a Free Flash movie player, which works either standalone, or
as a Firefox/Mozilla plugin.

Gnash supports the current Shockwave format, version 7. While all the
ActionScript classes exist, not all of the methods defined by the SWF
format documentation are implemented however, so not all flash movies
work 100% if they utilize any of the unimplemented methods. This is one
of the areas to work on to achieve full version 7 compliance.

This package contains the gstreamer-plugin for Broadcom CrystalHD
decoder chip.

HP DriveGuard for SuSE. Can protect hard disks on HP laptops by
spinning them down when shaking or free-fall is detected.

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.
