Wireless Transmission of Audio Using Adaptive Lossless Coding

Document Thumbnail

In audio devices, such as smartphones, media players and wireless headsets, designers face the conflicting requirements of elevating coded audio quality and reducing algorithm complexity, device power dissipation and transmission bit-rates. As a result, there are significant challenges in providing highest-quality real-time audio streaming between devices over wireless networks. Mathematically-lossless audio coding algorithms are an attractive means of maximizing coded audio quality. However, in the context of wireless audio transmission between portable devices, characteristics of such algorithms such as modest levels of bandwidth reduction, encoding complexity and robustness to data loss need to be carefully controlled. Such control can be elegantly engineered by incorporating real-time adaptation and scaling into the audio coding algorithm itself. This paper describes a lossless audio coding algorithm called apt-X Lossless, which has been designed with scalability and automated adaptation as its principal charateristics.
