Abstract
This paper presents an extension and global optimization of a bit-allocation strategy for use in a low delay subband ADPCM-based audio coding scheme. The framework employed for the assignment of bits to subband quantizers is based on a subband level estimation of the signals used for the prediction error normalization. It is modified to reduce switching artifacts and extended to contain a mapping to predefined allocation presets.
