  • Abstract
    This paper presents advanced audio zip (AAZ), an audio codec that provides the fine granular bit-rate scalability from lossy to lossless coding. Perceptually embedded coding principle is employed in AAZ to provide lossy reconstruction with optimal perceptual quality at intermediate bit-rates. AAZ also provides the backward compatibility where the lossless bit-stream embeds a compliant MPEG-4 AAC bit-stream.
