As outlined in a previous paper entitled Application of Local Network Concept to Audio Equipment, presented at the 80th AES Convention, the concept of distributed processing is essential in establishing sophisticated and flexible Audio Systems. This requires the definition of a Network Architecture and the selection of a Real-Time Operating System. In this paper, a practical application of the concept of Network Architecture to advanced Audio editing and synchronizing is illustrated. The Network Architecture selected (APIB, for Audio Purpose Interface Bus) was defined specifically for digital multi-channel recording. A Real-Time Operating System called RT80Z was specifically designed for describing editing and synchronizing tasks. The combination of RT80Z and the APIB protocol yields a total system of great effectiveness and flexibility which supports sophisticated Audio Systems.
