Journal ArticleDOI
Perceptual audio coding using adaptive pre- and post-filters and lossless compression
TL;DR: A subjective listening test of the combined pre-filter/lossless coder and a state-of-the-art perceptual audio coder (PAC) shows that the new method achieves a comparable compression ratio and audio quality with a lower delay.
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.
Patent
Method and apparatus for scalable encoding and method and apparatus for scalable decoding
Ralf Geiger,Thomas Sporer,Karlheinz Brandenburg,Juergen Herre,Juergen Koller,Gerald Schuller +5 more
TL;DR: In this article, the authors propose an apparatus for scalable encoding a spectrum of a signal including audio and/or video information, with the spectrum comprising binary spectral values, including a means for generating a first sub-scaling layer and a second sub-scale layer in addition to forming the encoded signal.
Patent
Audio encoder, audio decoder and audio processor having a dynamically variable warping characteristic
Juergen Herre,Bernhard Grill,Markus Multrus,Stefan Bayer,Ulrich Kraemer,Jens Hirschfeld,Stefan Wabnik,Gerald Schuller +7 more
TL;DR: In this article, a controller is connected for providing the time-varying control signal, which depends on the audio signal, and the controller is introduced to an encoding processor having different encoding algorithms adapted to a specific signal pattern.
