Overflow 0.6.0 have just been released.

We're pleased to announce the release of Overflow  0.6.0. Overflow is a free (GPL/LGPL) "data flow oriented" development environment. It can be use to build complex applications by combining small, reusable building blocks. In some way, it has similarities with Simulink and LabView, although it is not designed (and far) to be a "clone" of any of them. Download it from sourceforge  here.
It is written in C++ and features a plugin mechanism that allows plugins/toolboxes to be easiliy added. Overflow currently includes the following toolboxes:

- Audio/Signal processing
- Speech processing (part of the Open Mind Speech project)
- Vector quantization
- Neural network
- Fuzzy logic
- Real-time audio effect processing (early stage)
- Linear algebra using LAPACK (early stage)
- Image processing (early stage)

This release brings a number of important improvements:

- Many, many improvements to the gnome GUI (copy/paste, tooltips, bug fix, ...)
- C++ code generator (generated code can now be compiled on Win32)
- Basic networking support
- Improved debugging
- Speed improvements (also, auto-detection of 3DNow! and SSE)
- Overflow "shell scripts" (#! files)
- Lots of fixed bugs
- Big code cleanup and simplification (warning, this breaks some minor things)

There are also good news for the project. Overflow has been adopted by InfoSpace Speech Solutions for implementing part of a speech recognition engine and should ship in a future version of the product. Note that Jean-Marc Valin (project admin) works for InfoSpace / LocusDialog.
Overflow is now also used in the LABORIUS mobile robotics lab at University of Sherbrooke and a robot control toolbox is soon to be released!

There is now an on-line survey on SourceForge. Tell us what you think about Overflow!
 

Overflow 0.5.0 have just been released.  This new release brings a number of improvements over version 0.4.3.

These improvements include:

    - Binary I/O (serialization/unserialization) of objects
    - Major improvements to object ASCII I/O, mostly with the Vector type
    - Default FFT implementation when FFTW is not available
    - Possibility of passing any object type as a parameter from the GUI
    - gcc 2.96-RH support
    - Performance improvements
    - Fixes for Piper compatibility
    - Several new nodes

    Issues:

    - It is not clear whether Overflow compiles with gcc 3.0 installed in
         the standard (/usr) path

Overflow 0.4.3 has been released. This is a minor release which provides the functionality for speaker identification system (authentification of the speaker) . The files are available at : ftp://freespeech.sourceforge.net/pub/freespeech/speaker_verification-0.0.1.tgz

You need to install the latest version (0.4.3) of Overflow to use the speaker identification system.

It's been a while since the last update. Lots of new stuff has been committed recently and we're working on stabilizing the code before a new release. Recent updates include optimizations, better portability and of course, new nodes.
