Scalable Parametric Audio Coder for Internet Audio Streaming

For Internet audio streaming purposes, a good trade-off between bit rate reduction and audio quality is achieved by using parametric audio coding. A scalable parametric coder has been optimized for this requirement, avoiding differential encoding and using a layered scheme for changing straightforwardly the bit rate. The results reveal our coder as a good candidate for massive distributed audio applications, like music on demand, radio broadcasting or real-time streaming audio. Nevertheless, real-time scalable parametric audio streaming requires a complete communication protocol to achieve the goal of network transparency due to best-effort QoS of Internet. In this article some ideas for the design of a new embedded variable audio control protocol are shown.
