Overview of the EVS codec architecture

TL;DR: An overview of the underlying architecture as well as the novel technologies in the EVS codec are given and listening test results showing the performance of the new codec in terms of compression and speech/audio quality are presented.
Patent

Method and device for sound activity detection and sound signal classification

TL;DR: In this paper, a method for estimating the tonality of a sound signal was proposed, based on a correlation map between the current residual spectrum and a previous residual spectrum for each detected peak.
Patent

Device and method for frame erasure concealment in a pcm codec interoperable with the itu-t recommendation g.711

TL;DR: In this paper, the authors propose a method for resynchronization and recovery after frame erasure concealment of an encoded sound signal, which includes decoding, in a current frame, a correctly received signal after the Frame erasure.

G.711.1: A wideband extension to ITU-T G.711

TL;DR: This paper describes a scalable coder - G.711.1 - which has been standardized by ITU-T for wideband telephony and voice over IP applications and fulfils all the requirements defined in the terms of reference.

Device and method for noise shaping in a multilayer embedded codec interoperable with the itu-t g.711 standard

TL;DR: In this paper, the authors proposed a method for noise shaping in a multilayer codec, including at least Layer 1 and 2, which includes: at an encoder, producing an encoded sound signal in Layer 1 including Layer 1 noise shaping, and producing a Layer 2 enhancement signal; at a decoder, decoding the Layer 1 encoded sound signals to produce a synthesis signal, decoding enhancement signal, filtering the enhancement signal through the transfer function, and adding the filtered enhancement signal to the synthesis signal to produce an output signal including contributions from Layer 1, 2.
