F. Kossentini et al., AUDIO CODING USING VARIABLE-DEPTH MULTISTAGE QUANTIZATION, IEEE transactions on speech and audio processing, 6(2), 1998, pp. 186-189
An algorithm for high-quality coding of 48 kHz sampled audio signals i
s presented. The algorithm employs a perceptual transform and a variab
le-depth multistage quantizer. The resulting audio reproduction qualit
y is better than that of the Motion Pictures Expert Group (MPEG) layer
I coder and roughly equivalent to that of the MPEG layer II coder.
