IEEE Workshop on Multimedia Signal Processing
作者: Matteo Nucci Marco Tagliasacchi Stefano Tubaro Dipartimento di Elettronica P.zza Leonardo da Vinci Milano Italy
We present a content-based system for the analysis of near-duplicate audio tracks. The objective is to infer the structure of modifications, represented as trees, underneath a pool of near-duplicates, possibly specify... 详细信息

IET COMMUNICATIONS 2012年 第2期6卷 172-178页
作者: Oztoprak, H. Villette, S. Kondoz, A. Univ Surrey Ctr Vis Speech & Signal Proc Guildford GU2 7XH Surrey England
A scheme named index assignment-based channel coding (IACC) has been developed for resilience of speech/audio codecs against the bit errors commonly experienced in wireless channels. Although IACC is a type of joint s... 详细信息

IEEE Workshop on Applications of Signal Processing to audio and Acoustics
作者: Tom Bäckström Sascha Disch Fraunhofer Institute of Integrated Circuits and Systems Erlangen Germany Leibniz Universität Hannover Hanover Germany
audio transform coding methods generally employ an assumption of locally stationary signals. However, as demands on coding efficiency increase, the assumption of stationarity becomes increasingly challenging. In this ... 详细信息

IEEE International Conference on Acoustics, Speech, and Signal Processing
作者: Christian Neukam Frederik Nagel Gerald Schuller Michael Schnabel Fraunhofer IIS Am Wolfsmantel 33 91058 Erlangen Germany Ilmenau University of Technology Ehrenbergstr. 29 98693 Ilmenau Germany
Modern audio coding technologies apply methods of bandwidth extension (BWE) to efficiently represent audio data at low bitrates. An established method is the well-known spectral band replication (SBR) that is part of ... 详细信息

IEEE Workshop on Applications of Signal Processing to audio and Acoustics
作者: Shigeki Miyabe Keisuke Masatoki Hiroshi Saruwatari Kiyohiro Shikano Toshiyuki Nomura University of Tokyo Tokyo Japan Nara Institute of Science and Technology Nara Japan NEC Corporation Limited Kanagawa Japan
Binaural cue coding, which is a representing low bit-rate coding of multichannel audio, generates large distortion when the audio data have complex spatial image, such as symphony. Such distortion caused by the low fr... 详细信息

IEEE Workshop on Applications of Signal Processing to audio and Acoustics
作者: Minyue Li Jan Skoglund W. Bastiaan Kleijn Google Inc. Mountain View CA
Multichannel audio coding is studied from a rate-distortion theoretical viewpoint. Two practical coding techniques, both of which are based on rate-distortion optimization, are also proposed. The first technique decor... 详细信息

作者: Minyue Li Janusz Klejsa Alexey Ozerov W. Bastiaan Kleijn School of Electrical Engineering KTH Royal Institute of Technology Stockholm Sweden Technicolor Inc. Cesson-Sevigne France School of Engineering and Computer Science Victoria University of Wellington New Zealand
The coding of audio-visual signals is generally based on different paradigms for high and low rates. At high rates the signal is approximated directly and at low rates only signal features are transmitted. The recentl... 详细信息
