An audio coding system encodes and decodes audio signals as a plurality of independent layers of coded audio data. A basic representation of the original audio signal may be reconstructed from decoding of a single layer of coded audio data. However, a more complete representation of the original audio signal is reconstructed by decoding additional layers of coded audio data.

A Resource-scalable Unifying Framework for Aural Signal Coding. The objective of this project is to achieve a comprehensive, unifying framework and corresponding universal methodologies for the coding of aural signals. The challenges are due to the combination of elusive perceptual criteria, complex signal structures, and great diversity in signal type, operational setting, …

One of the aspects that plays a role in this suboptimality is the entropy coding. In practical audio coding systems including MPEG advanced audio coding (AAC), the transform domain coefficients are quantized using an entropy-constrained quantizer. In MPEG-4 scalable AAC (S-AAC), the quantization and coding are performed separately at each layer.

scalable audio coding into a single coder framework while providing backward compatibility to MPEG Advanced Audio Coding (AAC) at the bit-stream level. Despite its abundant functionalities, SLS still achieves a compression performance that is comparable to state-of-the-art non-scalable lossless audio coding algorithms. As a result, SLS
