FFTW is a C subroutine library for computing the Discrete Fourier
Transform (DFT) in one or more dimensions, of both real and complex
data, and of arbitrary input size.

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.

JACK is a low-latency audio server written primarily for the Linux
operating system. It can connect a number of different applications to
an audio device, as well as allow them to share audio between
themselves. Its clients can run in their own processes (as a normal
application), or they can run within a JACK server (as a plug-in).

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.

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.

This package is based on the package 'lcms' from project 'openSUSE:Factory'.

Little cms is a small speed optimized color management engine.

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

This library aims to be a friendly, portable C implementation of the AV1 Image
File Format, as described here:

https://aomediacodec.github.io/av1-avif/

This package is based on the package 'libcdaudio' from project 'openSUSE:Factory'.

libcdaudio is a library designed to provide functions to control
operation of a CD-ROM when playing audio CDs. It also contains
functions for CDDB and CD index lookup.

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

Generic C framework used and developed by the Icecast project

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.

Theora is a free video codec based on VP3. The package contains the
library that can decode and encode Theora streams. Theora is also able
to playback VP3 streams.

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.
