which distortion is introduced into the reconstruction process in the preferred embodiment a decision to ignore or repeat if made at all occurs only once per buffer cycle during normal operation the timing drift difference between the input rate and the output rate is initially neglected once per buffer cycle however a re synch signal is issued re synch will force at least some of the data stream to be ignored if the input rate is faster than the output rate over the length of the buffer conversely re synch will cause at least some of the data stream to be repeated if the input rate is slower than the output rate over the length of the buffer in this manner the timing drift error caused by differences between the input rate and the output rate are resolved modified data stream processing provides yet another means for maintaining the quality of digital speech during digitized voice reconstruction while the preferred embodiment suggests modifying data stream processing only once per buffer cycle it will be appreciated that an alternative solution is dispersing the data stream processing modifications over the length of the buffer cycle thereby smoothing the effect of timing drift error in addition it will be appreciated that modifying the processing of the data stream prior to storage in the circular buffer achieves the aforementioned goals without departing from the spirit of the present invention in the preferred embodiment rather than synchronizing a receiver 39 s master clock to.
