Abstract

Differential encoding is a well known low complexity coding technique. Its use in the coding of wideband audio is limited by its inability to follow rapid changes in the signal. This is a serious drawback when coding high fidelity audio where this inability can seriously degrade the perceptual quality of the reconstruction. This overload problem can be remedied by using a recursively indexed quantizer. In this paper we present some empirical results for the differential coding of audio signals.
