Adaptive WP tree derived via dynamic algorithm transforms (DAT's) is presented. The DAT is to define parameter of input audio signals (subband entropy) and output codered sequences (subband rate) for the given embedded system architecture. A DAT-based pipe-line processor (WP trees analysis (encoder) and synthesis (decoder) algorithms) based on a reconfigurable hardware (such as SRAM-FPGA plus distributed arithmetic) is described.
