Abstract
The authors propose a new optimal subband bit allocation procedure whi ch is well suited for low bit rate applications. Contrary to most bit allocation algorithms, this method does not use approximate distortion and rate models but finds the optimal solution among all possible com binations of quantisers. Associated with a 'stack-run' codec, it is sh own to improve on the performance obtained by the well-known EZW algor ithm.
