ISO/MPEG AUDIO CODING

International Journal of High Speed Electronics and Systems, 1997
The Moving Pictures Expert Group within the International Organization of Standardization (ISO/MPEG) has developed, and is presently developing, a series of audiovisual standards. Its audio coding standard MPEG Phase 1 is the first international standard in the field of high quality digital audio compression and has been applied in many areas, both ...

Joint speech/audio coding based scalable perceptual audio coding

2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS), 2014
With the technical evolution of global mobile communications, various heterogeneous communication environments, frequently fluctuant bandwidth and multiform signals put new challenges to coding technology of multimedia signals. Scalable Audio Coding (SAC) can provide smooth transition between different coding qualities, which is an optimal choice for ...

Parametric audio coding

WCC 2000 - ICCT 2000. 2000 International Conference on Communication Technology Proceedings (Cat. No.00EX420), 2002
For very low bit rate audio coding applications in mobile communications or on the Internet, parametric audio coding has evolved as a technique complementing the more traditional approaches. These are transform codecs originally designed for achieving CD-like quality on one hand, and specialized speech codecs on the other hand. Both of these techniques

Lossless audio hiding method for synchronous audio-video coding

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
The absence of audio-video synchronization has been one of the most annoying effects in multimedia application. This paper proposes a lossless information hiding method for synchronous audio-video coding. The binary bits of an encoded audio signal are embedded into the DCT domain of the video data to produce synchronous hybrid signal which is further ...

DRA Audio Coding Standard

Applied Mechanics and Materials, 2013
Chinas DRA audio coding standard is shown to be a barebone transform coder, utilizing transient-localized MDCT for improved pre-echo suppression and statistic allocation of codebooks for high entropy coding efficiency. A signal path of up to 24 bits is provided throughout the codec so that highest audio quality can be delivered if bit rate suffices ...

Parametric binaural audio coding

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
A spatial audio scene consists of discrete audio sources and ambience. The 3D audio image is observed due to the directional sounds, but even more important is the reverberation and so called room effect caused by the properties of the space, the sources and listener location.

Perceptual Audio Coding

2014
Abstract Audio Coding has proliferated as a mainstream enabling digital technology for all types of applications that provide audio and multimedia to consumers using transmission or storage channels with limited capacity. Since its infancies in the eighties and early nineties, the technology behind low bitrate audio coding has developed rapidly until
