Abstract
A high quality time code and word clock synchronization is essential to prevent audio drop outs and flutters in sound studios. A bad adjustment of time code generators respectively word clock synchronizers requires extensive error checks in synchronization networks. For this reason, a new measurement method is presented which enables sound engineers to measure longitudinal time code jitter and to check time code / word clock synchronization. Annoying audible artifacts in sound studios can be traced back on measured time code jitter and on loss of synchronization of the used time code / word clock synchronizer. With this method a time code jitter measurement accuracy of +/- 20 microsecond can be achieved.
