Ecasound
is a software package designed for multitrack audio
processing. It can be used for simple tasks like audio playback,
recording and format conversions, as well as for multitrack effect
processing, mixing, recording and signal recycling...........

RTMix
is an open-source (GPL-licensed) software application designed to provide stable,
user-friendly, standardized, and efficient performance interface that enables
performer(s) to interact with both the computer and each other in the least
obtrusive fashion. What this means is that RTMix offers an array of visual
stimuli that can be utilized on-stage in order to coordinate various performing
forces utilizing diverse media.

Demolition
is a destruction testing tool for LADSPA plugins. It's intended mostly
for sanity checking your own code before you release it to the world.
Demolition is a work in progress.
I try to demonstrate how you can use a text-based linux environment
(console) as a nicely equipped recording-studio. At the moment only the basic
chapters of this guide and a few early audio-examples are online.

MFFM Multimedia Time Code
These C++ headers are great for managing time code ... it automaticly
expresses time code in any base units ... which must be set up by the
user ... can run any type of SMPTE, CDDA, etc. .. It is templated so you
can handle any data type ... audio, video, audio/video.... It also
includes a type II filter for audio processing ... this is very handy
for filtering audio with FIR or IIR filters.
MFFM Time Scale Modification for Audio
This is an engine which stretches audio without changing its pitch. The
C++ headers are really easy to use in 3rd party apps.

- minor build system fix.
- extensive API improvements
- new module module-combine for combining multiple sound cards into one
- gcc 2.95 compatibility

PKAudio
is an audio lib/daemon that makes asynchronous communication with a
realtime audio engine from high-level languages like python easy. It is
incredibly simple to write extension modules (subclass, implement two simple
methods, link with executable), and is a very nice place to start for someone
looking to get right to the important part of their dsp application. A Python
module is included.
PKSampler is a DJ sampler intended for a touch screen. It uses python and qt
to animate real 3D widgets created with PoVRay. Check out the screen shots!
Read the pkaudio release notes for compilation help. should be simple.
PKSampler is written in python, so there isn't any setup.

Timemachine is a JACK app for recording sounds that have just happened.
It can also be used as a generic JACK sound recorder. Read the website for
more retails.
This version adds:
Interactive command line mode by Mario Lang (no X11 needed)
Generates WAV as well as W64 files, extension is now right
Can specify JACK ports to connect to on the command line

an update of JJack - Java bridge API for JACK has been released.
Version 0.2 integrates much better with the JACK thread architecture.
The JACK processing-thread now itself executes Java code inside the Java

LASH Audio Session Handler (LASH)
LASH is a session management system for JACK and ALSA
audio applications on GNU/Linux.
Qjackctl
is a simple Qt application to control the JACK sound server daemon,
specific for the Linux Audio Desktop infrastructure.
Written in C++ around the Qt3 toolkit for X11, most exclusively using Qt Designer.
Provides a simple GUI dialog for setting several JACK daemon parameters, which are
properly saved between sessions, and a way control of the status of the audio server
daemon. With time, this primordial interface has become richer by including a
enhanced patchbay and connection control features.
