As the complexity of the 3G mobile communications environment, the limitation of the wireless transmission frequency band resources, in order to achieve the transmission and reconstruction of low bit rate, high-quality audio signal, a modified EAAC+ mobile audio coding algorithm based on the existing technology of speech or audio bandwidth extension research is presented in this paper. The algorithm...
In the past decades, technical developments have enabled the delivery of sophisticated mobile spatial audio signals to consumers, over links that range very widely in quality, requiring decisions to be made about the tradeoffs between different aspects of audio quality. It is therefore important to determine the most important spatial quality attributes of reproduced sound fields and to find ways...
During the last decade, new mobile multimedia applications have emerged for mobile and network multimedia, wireless multimedia communication, audio/video teleconferencing, remote assistance, digital storage systems, secure audio transmission and so on. In order to meet these requirements, tremendous research efforts have been put in the development of efficient digital audio coding technologies. In...
During the last decade, new digital audio applications have emerged for network multimedia, wireless multimedia communication, and multimedia computing. In response of this need, considerable research has been devoted to the development of high-fidelity digital audio. Several international or commercial digital audio standards are also presented, such as the ISO/MPEG family and the Dolby AC-3. Although...
