Patent
Method and device for efficient frame erasure concealment in linear predictive based speech codecs
Jelinek Milan,Philippe Gournay +1 more
TL;DR: In this article, a method and device for improving concealment of frame erasure caused by frames of an encoded sound signal erased during transmission from an encoder (106) to a decoder (110), and for accelerating recovery of the decoder after non erased frames of the encoded sound signals have been received.
Patent
Multi-resolution switched audio encoding/decoding scheme
Max Neuendorf,Stefan Bayer,Jeremie Lecomte,Guillaume Fuchs,Julien Robilliard,Nikolaus Rettelbach,Frederik Nagel,Ralf Geiger,Markus Multrus,Bernhard Grill,Philippe Gournay,Redwan Salami +11 more
TL;DR: In this paper, a signal analyzer for analyzing the audio signal is provided, which determines whether an audio portion is effective in the encoder output signal as a first encoded signal from the first encoding branch or as a second encoded message from a second encoding branch.
Proceedings ArticleDOI
Unified speech and audio coding scheme for high quality at low bitrates
Max Neuendorf,Philippe Gournay,Markus Multrus,Jeremie Lecomte,B. Bessette,R. Geiger,Stefan Bayer,Guillaume Fuchs,Johannes Hilpert,Nikolaus Rettelbach,Redwan Salami,Gerald Schuller,Roch Lefebvre,Grill Bernhard +13 more
TL;DR: This new codec forms the basis of the reference model in the ongoing MPEG standardization activity for Unified Speech and Audio Coding, which results in a codec that exhibits consistently high quality for speech, music and mixed audio content.
Journal Article
MPEG Unified Speech and Audio Coding - The ISO/MPEG Standard for High-Efficiency Audio Coding of All Content Types
Max Neuendorf,Markus Multrus,Nikolaus Rettelbach,Guillaume Fuchs,Julien Robilliard,Jeremie Lecomte,Stephan Wilde,Stefan Bayer,Sascha Disch,Christian Helmrich,Roch Lefebvre,Philippe Gournay,Bruno Bessette,Jimmy Lapierre,Kristofer Kjörling,Heiko Purnhagen,Lars Villemoes,Werner Oomen,Erik Gosuinus Petrus Schuijers,Kei Kikuiri,Toru Chinen,Takeshi Norimatsu,Chong Kok Seng,Eunmi Oh,Miyoung Kim,Schuyler Quackenbush,Bernhard Grill +26 more
TL;DR: All aspects of this standardization eort are outlined, starting with the history and motivation of the MPEG work item, describing all technical features of the nal system, and further discussing listening test results and performance numbers which show the advantages of the new system over current state-of-the-art codecs.
Patent
Audio encoding/decoding scheme having a switchable bypass
Bernhard Grill,Stefan Bayer,Guillaume Fuchs,Geyersberger Stefan,Geiger Ralf,Hilpert Johannes,Ulrich Krämer,Jeremie Lecomte,Markus Multrus,Max Neuendorf,Harald Popp,Nikolaus Rettelbach,Roch Lefebvre,Bessette Bruno,Jimmy Lapierre,Redwan Salami,Philippe Gournay +16 more
TL;DR: An apparatus for encoding comprises a first domain converter (510), a switchable bypass (50), a second domain Converter (410), a first processor (420) and a second processor (520) to obtain an encoded audio signal having different signal portions represented by coded data in different domains, which have been coded by different coding algorithms as discussed by the authors.
