SOFTWARE-BASED AUDIO CLOCK DRIFT DETECTION AND CORRECTION METHOD

A software rational resampler (312) is located in an audio buffer path to correct clock differences between a sender and a receiver. Counters track the frames into an audio buffer (308) from the sender and the frames removed from an audio buffer (316) by the receiver. A change in the difference betw...

Zusammenfassung:	A software rational resampler (312) is located in an audio buffer path to correct clock differences between a sender and a receiver. Counters track the frames into an audio buffer (308) from the sender and the frames removed from an audio buffer (316) by the receiver. A change in the difference between the sender frame counter (310) and the receiver frame counter (314) is detected and used as a triggering event to initiate changing (239) the parameters of the software rational resampler (312). The software rational resampler parameters may be saved so that if audio is received from the same source, the software rational resampler (312) is configured on system startup.
