abstract = {The Opus codec is used in several applications fields of speech and audio
communication. This article describes the instrumental quality assessment of Opus-
coded speech in a web browser-based real-time communication using POLQA and
AQuA method. Furthermore, we tested Opus with mixed vocal and music signals
and also performed a perceptual test. WebRTC framework-coded speech achieves a
similar MOS assessment compared to standalone coding. The observed degradations
depend on signal bandwidth, on variations in speech (e. g. by emotions) or in music
(vocal vs. instrumental) and on the assessment method.},
