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.

This package contains some tools for Ogg Vorbis:

oggenc (an encoder) and ogg123 (a playback tool). It also has vorbiscomment (to
add comments to Vorbis files), ogginfo (to give all useful information about an
Ogg file, including streams in it), oggdec (a simple command line decoder), and
vcut (which allows you to cut up Vorbis files).

ZynAddSubFX is a many-featured real-time software synthesizer for
Linux. Features include polyphony and multitimbrel and microtonal
capabilities. It includes randomness of some parameters, which can make
warm sounds, like analog synthesizers. This program has system and
insertion effects, too.

ALSA stands for Advanced Linux Sound Architecture. It supports many
PCI, ISA PnP and USB sound cards.

This package contains the ALSA init scripts to start the sound system
on your Linux box. To set it up, run yast2 or alsaconf.

Various firmware data files for ALSA drivers.

This package contains the wrapper library and script to run OSS
applications using ALSA API.

This package contains the extra plug-ins for the ALSA library.

Various tools for ALSA including DSP loaders.

This package contains utility programs supporting ALSA, Advanced Linux
Sound Architecture.

AlsaMixerGui is an FLTK-based front-end for alsamixer. It is written
directly on top of the alsamixer source, so it should provide the same
functionality.

AsciiDoc is a text document format for writing short documents,
articles, books, and UNIX man pages. AsciiDoc files can be translated
to HTML and DocBook markups using the asciidoc command.

ASeqView is an ALSA sequencer user client that works as an event viewer
and event filter. It visualizes received events, such as note on and
off, controls, and pitch wheels, using bar graphs as seen in many
sequencer applications.

Aubio is a library for real time audio labelling. Its features include
segmenting a sound file before each of its attacks, performing pitch
detection, tapping the beat and producing midi streams from live audio.
The name aubio comes from 'audio' with a typo: several transcription
errors are likely to be found in the results too.

The AWESFX package includes utility programs for controlling the
wavetable function on SB AWE32/64 and Emu10k1 sound cards.

cachefilesd is a user-space management daemon for CacheFiles, a generic
caching framework for mounted filesystems.

The compcache is a RAM-based block device acting as a swap disk. This
can effectively increase the available memory on your machine by
virtually swapping pages into the compressed memory.

This package contains the boot script for loading/unloading the
modules. The modules are contained in compcache-kmp packages.

This package contains the library to support the hardware decoding of
H.264 video stream with Broadcom Crystal HD chips.

Csound is a software synthesis program. It is fully modular and
supports an unlimited amount of oscillators and filters.

Disposable Soft Synth Interface (DSSI, pronounced "dizzy") is a
proposal for a plug-in API for software instruments (soft synths) with
user interfaces, permitting them to be hosted in-process by Linux audio
applications. Think of it as LADSPA-for-instruments or something
comparable to a simpler version of VSTi.

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.

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.
