Dynamic algorithm transforms for reconfigurable real-time audio coding processor

Abstract

In this paper, dynamic algorithm transforms (DAT) for reconfigurable real-time processor for audio coding based on the adaptive wavelet packet decomposition are presented. The DAT technique is used to constrain a minimum cost subband decomposition of wavelet transform by maximizing the minimum masking threshold (which is limited by the perceptual entropy) in every subband for the given embedded processor architecture and temporal resolution.
