Abstract. The quality of audio in IP telephony is significantly influ-
enced by the impact of packet loss rate, burstiness and distribution
on a specific audio compression technique. In this paper, we propose a
novel statistical-based on-line audio quality assessment framework, Au-
dio Genome, that can deduce the audio quality of an on-going Inter-
net audio for many different codecs under any network loss condition
at real-time. Our approach is superior to proposed learning-based tech-
niques in terms of computational speed and ease of deployment. Our
extensive evaluation experiments, that include large simulation scenar-
ios, show that our approach is accurate and viable for adaptive real-time
audio mechanisms. Finally, we show a deployment of Audio Genome as
an integral part of an adaptive rate control mechanism.
1 Introduction
Audio codecs have a diverse range of compression degrees and underlying tech-
nologies. The main factors that significantly influence the evaluation of audio
