ABSTRACT:
A digital signal formed from successive words representing quantized samples of sound information and comprising silent periods is synchronized with a local reading clock. For that, the words are stored in a random access memory as they arrive, they are read at the frequency of the local clock and the filling rate of the store is permanently determined. A comparator compares this rate with a given range. If the filling rate is greater than a maximum threshold or less than a minimum threshold, the contents of the memory are modified at the first silent interval which appears.
