Signal Synchronisation in Digital Audio
The paper details an approach to synchronising independent digital audio signals permitting technical processing such as mixing in a studio centre. Digital standards for signals and their interconnection via the serial audio and data multiplex are taken into account. The system uses the digital synchronizer technique allied to agreed standards of sample frequency stability and involves minimal audio and data corruption. Operating overheads are low and there are no special features to be added to studio digital equipment of wider application. Practical proposals using proven designs are described. Audio-video timing compatibility is considered.
