Frequency-domain Comfort Noise Generation for Discontinuous Transmission in EVS

Anthony Lombard, Stephan Wilde, Emmanuel Ravelli, Stefan Döhla, Guillaume Fuchs, Martin Dietz

ICASSP 2015accepted

Discontinuous Transmission (DTX) is an efficient way to drastically reduce the transmission rate of a communication codec in the absence of voice input. In this mode, most frames that are determined to consist of background noise only are dropped from transmission and replaced by some Comfort Noise…

Overview of the EVS codec architecture

Martin Dietz, Markus Multrus, Vaclav Eksler, Vladimir Malenovsky, Erik Norvell, Harald Pobloth +15

ICASSP 2015accepted

The recently standardized 3GPP codec for Enhanced Voice Services (EVS) offers new features and improvements for low-delay real-time communication systems. Based on a novel, switched low-delay speech/audio codec, the EVS codec contains various tools for better compression efficiency and higher qualit…
