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).

Meterbridge is a JACK (JACK Audio Connection Kit) client for
visualizing audio signals.

This package contains utility programs for NILFS v2.

Perl 5.7.3 and later ships with an adequate set of Chinese encodings,
including the most used CP950, CP936 (also known as GBK), Big5,
Big5-HKSCS, EUC-CN, HZ, and ISO-IR-165.

However, the numbers of Chinese encodings are staggering, and a
complete coverage will easily increase the size of perl distribution by
several megabytes; hence, this CPAN module tries to provide the rest of
them.

pmidi is a command line MIDI player for ALSA.

PortAudio is a portable audio I/O library designed for cross-platform
support of audio. It uses a callback mechanism to request audio
processing. Audio can be generated in various formats, including 32 bit
floating point, and will be converted to the native format internally.

This package provides the Python binding to ALSA.

JACK Audio Connection Kit - Qt GUI Interface: A simple Qt application
to control the JACK server. Written in C++ around the Qt4 toolkit
for X11, most exclusively using Qt Designer. Provides a simple GUI
dialog for setting several JACK server parameters, which are properly
saved between sessions, and a way control of the status of the audio
server. With time, this primordial interface has become richer by
including a enhanced patchbay and connection control features.

The resample program is a high-quality resampling program. For example,
it can be used to convert the sampling rate from 48 kHz (used by DAT
machines) to 44.1 kHz (the standard sampling rate for Compact Discs).

Seq24 is a real-time midi sequencer. It was created to provide a very
simple interface for editing and playing MIDI 'loops.'

Snd is a sound editor modelled loosely after Emacs and an old,
sorely-missed PDP-10 sound editor named Dpysnd. It can accommodate any
number of sounds each with any number of channels and can be customized
and extended using guile and guile-gtk.

Solfege is an eartraining program for X written in python, using
the GTK+ and GNOME libraries. To use this software you need some
basic knowledge about music theory. Using solfege you can learn
to recognise melodic and harmonic intervals, compare interval
sizes, sing the intervals the computer asks for, identify chords,
sing chords, scales, dictation and remember rhythmic patterns.

Speex is a patent free audio codec designed especially for voice
(unlike Vorbis which targets general audio) signals and providing good
narrowband and wideband quality. This project aims to be complementary
to the Vorbis codec.

StGIT is a Python application providing similar functionality to Quilt
(i.e. pushing/popping patches to/from a stack) on top of GIT. These
operations are performed using GIT commands and the patches are stored
as GIT commit objects, allowing easy merging of the StGIT patches into
other repositories using standard GIT functionality.

TiMidity plays MIDI files without external MIDI instruments and
converts MIDI files to WAV using GUS/patch and SoundFont for voice
data.

Vkeybd is a virtual keyboard (as in musical instrument) for AWE32/64,
raw MIDI, and ALSA sequencer drivers. It is written in Tcl/Tk. Enjoy
playing music with your "computer" keyboard.
