High Quality Audio Coder Using a Wavelet Packet Decomposition
웨이브렛 패킷을 이용한 고음질 오디오 부호화
Abstract
In this paper we propose high quality audio coding algorithm using psychoacoustic modelling and the adaptive wavelet Packet decomposition. The bit allocation scheme exploits the remnants of temporal correlations that exist in the wavelet packet coefficients by SPIHT. The proposed algorithm achieve almost transparent coding of monophonic compact disk(CD) quality signals at about 44 kbps.
