<p>A system and method for processing an audio signal and including a scalable audio coder (500) and a decoder. The coder (500) includes a multi-resolution transform processor (510), such as a modulated lapped transform (MLT) transform processor, a weighting processor (516), a uniform quantizer (512), a masking threshold spectrum processor, an entropy encoder (514). The coder (500) encodes the audio signal. Also, parametric modeling of the digitally encoded signal is performed to enhance encoding. The decoder comprises inverse components of the coder (500) for decoding the encoded audio signal.</p> |
