You can get the latest version of SigmaStudio from the Analog Devices website at http://www.analog.com/SigmaStudio. This is the programming tool for all of the SigmaDSP audio processors. You will need a myAnalog account in order to download (if you don't have an account, the page will help you to create one). The latest version will always be available at that link.
