Abstract

[WT-based coding allows for the control of frequency resolution to closely match the response of the human auditory system. The inherent shaping of the wavelet synthesis filter and a controlled bit allocation to the wavelet coefficients help to minimize the perceptually significant noise due to the quantization error in the residual. Experimental results show that WT-coders deliver superior quality to some audio standards when operating at the same bit rate and comparable quality to other codecs at lower bit rates. As a result, transform compression using WT can provide an efficient and flexible scheme for audio compression.]
