Abstract: A jitter buffer control for controlling a provision of a decoded audio content on the basis of an input audio content is configured to select a frame-based time scaling or a sample-based time scaling in a signal-adaptive manner. An audio decoder uses such a jitter buffer control.

Method and arrangement in a communication system
TL;DR: In this article, the decoding/playback part of received sound data packets in systems for transmission of sound over packet switched networks is discussed, where the lengths of received signal frames are manipulated by performing time expansion or time compression of one or more signal frames at time varying intervals and with time varying lengths of the expansion or compression, said intervals and said lengths being determined so as to maintain a continuous flow of signal samples to be played back.
