Hello, We're pleased to announce version 0.4.0 of Overflow (aka the Open Mind Speech environment, aka Piper PL). This new release brings a number of major improvements over version 0.3.0. Some of the changes are: * The VFLOW_PATH environment variable is no longer required (it's determined from the --prefix configure option) if you don't add your own nodes. * The FFTW library is no longer required to build Overflow. If you don't have it, the build will continue without FFT support. * It's now possible to have Feedback loops in a flow. This is done by using the "Feedback" node and a demo is available in the examples directory. * Overflow also supports throwing and catching exceptions within the flow using the "Throw" and "Catch" node. This is still undocumented. * Support for AMD 3D Now! instructions in vector primitives (use -D_USE_3DNOW) * Rewrite of the Neural network toolbox to make it faster * More stuff in the "examples" directory. * Updated html documentation * Better layout the links on the GUI (links can be broken lines) * As usual, a whole bunch of new node Overflow is a visual development environment, using a GNOME UI, that allows easy development of applications using toolboxes. Current toolboxes include signal processing, image processing, neural networks, vector quantization and more... Download, compile, enjoy, report bugs!
