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).

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.'
