This paper describes recent developments on the design of an advanced Audio Spectral Coder (ASC) that seeks: coding efficiency by combining source and perceptual audio coding techniques; bit stream semantic scalability by segmenting the audio signal into transients, sinusoids and noise; low delay coding by using a moderate transform size and no bit stream buffer; and embedded error robustness by not using interframe coding. The operation of ASC is explained, its performance is assessed using a few test results, and potential application areas are also addressed.
