Description of cooperation

Our collaboration involves joint development of digital audio effects, and specialized software and hardware for audio signal processing in real time. The SPLab focuses on the research and development of algorithms of digital audio effects, and other algorithms for digital audio signal processing and their real-time implementation in C++ environment in the form of plug-in modules for PC. The Audiffex company performs both final implementation of these plug-in modules for front-end users, and complete development of host applications for these modules. In recent years, this cooperation has extended to a musical effect system for the Surround sound systems. The SPLab team focuses on developing a specialized embedded hardware system for real-time processing of audio signals while the Audiffex team prepares modular software for this system, controlled remotely via the Internet.
