The C* Audio Plugin Suite, is a collection of highly refined LADSPA
units capable of (and intended for) realtime operation. The suite
includes DSP units emulating instrument amplifiers, stomp-box
classics, versatile 'virtual analogue' oscillators, fractal
oscillation, reverb, equalization and others.
DSSI (pronounced "dizzy") is an API for audio processing plugins,
particularly useful for software synthesis plugins with user
interfaces.
DSSI is an open and well-documented specification developed for use
in Linux audio applications, although portable to other platforms.
It may be thought of as LADSPA-for-instruments, or something
comparable to VSTi.
DSSI consists of a C language API for use by plugins and hosts,
based on the LADSPA API, and an OSC (Open Sound Control) API for
use in user interface to host communications. The DSSI specification
consists of an RFC which describes the background for the proposal
and defines the OSC part of the specification, and a documented
header file which defines the C API.
Many audio synthesis and recording packages are in use or in
development. These work in many different ways. LADSPA
provides a standard way for `plugin' audio processors to be used with
a wide range of these packages.
For instance, this allows a developer to make a reverb program and
bundle it into a LADSPA `plugin library.' Ordinary users can then use
this reverb within any LADSPA-friendly audio application.
DarkIce is an IceCast, IceCast2, and ShoutCast live audio streamer. It
records audio from an audio interface (e.g. sound card), encodes it and
sends it to a stream server.
DarkIce can encode in the following formats:
- MP3 (using the lame library)
- MP2 (using the twolame library)
- Ogg Vorbis
- AAC (using the faac library)
- AAC HEv2 (using libaacplus library)
DarkIce can send the encoded stream to the following streaming servers:
- ShoutCast
- IceCast 1.3.x and 2.x
- Darwin Streaming Server
- Archive the encoded audio in files
LASH is a session management system for JACK audio applications. It is an
implementation of a proposal that originated from this discussion. Its aim
is to allow you to have many different audio programs running at once, to
save their setup, close them down and then easily reload the setup at some
other time. LASH doesn't deal with any kind of audio data itself; it just
runs programs, deals with saving/loading (arbitrary) data and connects
different kinds of virtual audio ports together (currently JACK and ALSA
sequencer ports). It can also be used to move entire sessions between
computers, or post sessions on the Internet for download.
libmusicbrainz is a client library for accessing the MusicBrainz database
allowing metadata lookup for audio files. This is version 3.x which uses the
deprecated XML Web Service Version 1.
libopenspc provides a library that allows for the emulated playback of SPC
files, which are SNES audio files. It uses the SNEeSe emulator sound core for
accurate playback.
Python Audio Tools are a collection of audio handling programs which work from
the command line. These include programs for CD extraction, track conversion
from one audio format to another, track renaming and retagging, track
identification, CD burning from tracks, and more. Supports internationalized
track filenames and metadata using Unicode. Works with high-definition,
multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs
or CPU cores if available to greatly speed the transcoding process. Track
metadata can be retrieved from FreeDB, MusicBrainz or compatible servers.
libmusicbrainz is a client library for accessing the MusicBrainz database
allowing metadata lookup for audio files. This is version 5.x which supports
version 2 of the XML Web Service.
DAGRAB is a program for reading audio tracks from a CD into wav sound
files. An IDE CD-rom drive that supports digital audio is required.
