About our Software

Our vision stems from the fact that research commonly suffers from a creative backlog due to rewriting of common functions, and the time spent in debugging such things as file I/O. The ISIP Foundation Classes (IFCs) and software environment are designed to meet this need, providing everything from complex data structures to an abstract file I/O interface.

We provide support for our system on Linux as long as the minimum system requirements are met. The latest version of our system can be downloaded here. Then follow the simple quick start guide and you will be on your way.
