Abstract: An apparatus and method for detecting and analyzing spikes in network jitter and the estimation of a jitter buffer target size is disclosed. Detected spikes may be classified as jump spikes or slope spikes, and a clipped size of detected spikes may be used in the estimation of the jitter buffer target. Network characteristics and conditions may also be used in the estimation of the jitter buffer target size. Samples may be modified during playback adaptation to improve audio quality and maintain low delay of a receive chain.
