Overflow is a "data flow oriented" development environment which lets users build complex programs by visually connecting small, reusable building blocks. It is primarily designed as a research tool, but can also be used for real-time data processing. The package includes a visual debugger. It currently includes toolboxes for signal, speech, and image processing, vector quantization, fuzzy logic, real-time audio effect processing, and neural networks.
