OSC: Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. OSC’s advantages include interoperability, accuracy, flexibility, and enhanced organizations and documentation. This simple yet powerful protocol is remaining flexible and easy to implement. OSC has achieved wide use in fields including computer-based new interfaces for musical expression, wide-area and local-area networked distributed music systems and inter-process communication.
