Abstract

The performance of wavelets in terms of vanishing moments, regularity, and complexity is investigated for low bit-rate coding of audio signals. To assess the coding gain of wavelets, a codec model has been designed and implemented based on a wavelet packet algorithm and an auditory perception model combined with entropy noiseless coding. The wavelet packet-based coding approach is compared to the MPEG-audio international standard in terms of objective and subjective measurements and is shown to be superior to MPEG-audio Layer I and competitive with Layer II. The trade-offs between the two approaches are discussed.
