Joint speech/audio coding based scalable perceptual audio coding
2014 IEEE/ACIS 13th International Conference on Computer and Information Science (ICIS), 2014With 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 ...

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

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 ...
