Audio applications are now widely used in the Internet. Such applications require receiver playout buffers to smooth network delay variations and to reconstruct the periodic form of the transmitted packets. Packets arriving after their playout deadline are considered late and are not played out. Existing algorithms used in the Internet operate by adaptively adjusting the playout delay from talkspurt to talkspurt. There is an important tradeoff between loss percentage and average playout delay. Current algorithms fail to obtain a particular loss percentage. Controlling this parameter is a key characteristic for any playout adaptation algorithm. This paper presents a Moving Average algorithm for playout delay adaptation with tunable loss percentage. We show with trace-based simulations that, in most of the cases, our algorithm performs better than those implemented in popular audio tools, and this is for the range of loss rates of interest in interactive audio applications.
