| Abstract In this paper an efficient algorithm proposed to encode the audio signals with multirate capability. The algorithm based on combining discrete wavelet with DCT transform for maximum decorrelation. The coefficients of the frame are scaled and encoded using non uniform quantizer. The main features of this algorithm are: low complexity and near transparent audio quality resulted in the range 48 – 64 Kbps for most SQAM signals. The algorithm outperform much better than DWPT with SPIHT algorithm previously. Keyword : wavelet , DCT , audio , coding , Huffman , and psychoacoustics. | ||
