Abstract
Over the last decade, analysis-synthesis systems based on maximally decimated filter banks have emerged as one of the important techniques for speech and audio coding. For speech and audio signals, the analysis-synthesis filter bank can be thought of as modeling the human auditory system, where the critical band model of aural perception is reflected in the design of the filter banks. The constraints imposed by the aural model are best met by nonuniform analysis-synthesis systems in which the bandwidths of the channels increase with increasing frequency.
