AB  - With the increase of channel capacity in communication systems, several emerging applications require an acceptable reproduction quality for speech signals at low bit-rates, and a superior quality for any kinds of audio inputs when more bandwidth is available. To meet this requirement, we propose a new scalable audio coding algorithm. The proposed coder consists of a wideband speech coder embedded in a multi-layer transform coding algorithm. The transform coefficients are quantized using a scalable lattice vector quantization. The global system exhibits low computational complexity and memory requirements, and leads to a very fine grained scalability. The new coding algorithm is suitable for communications over heterogeneous networks with no or uneven guarantee on the quality of service (QoS) for packet delivery.
