A METHOD OF CONTROLLING THE QUANTIZATION NOISE OF THE WAVELET COEFFICIENTS IN PERCEPTUAL COMPRESSION OF AUDIO SIGNALS
Abstract
Discusses the quantization noise arising in the codec working in wavelet space, and the method of adaptation psychoacoustic model AAS (AMP AAS) to the calculation of the masking performed
in the wavelet domain.
