Improving audio conferencing

摘要

In this paper, we describe a range of audio problems that impact the effectiveness of audio conferences and detail the solutions we have devised to address these problems. We conducted an audio quality assessment to determine how differences in quality impact audio clarity, a remote person's experience connecting to a conference room , and social presence. Based on the results of this assessment, we examine the costs and benefits of increasing audio fidelity with respect to the network resources needed to support high-fidelity audio conferencing.
