Abstract
A generalised perceptual filter which aims to reduce the audible quantisation noise in low bit rate audio coding has been developed. The filter derivation is based on a psychoacoustic excitation pattern model. Experimental results show that the perceptual filter can reduce the audible quantisation noise in a sub-band coded audio signal
