This paper proposes a new digital audio coding method. It combines subband-coding with an interpolator that recovers the high frequency spectrum according to an analog audio signal model. The interpolator can be designed via sampled-data control theory. Efficient compression can be achieved by the Huffman coding at low bit-rate transmission. The …

2. HUFFMAN CODING Hu man coding is an entropy encoding algorithm [3] used for lossless data compression and is commonly used in me-dia compression such as video and audio. By using Hu man coding, we can e ciently allocate bits to represent symbols in the data by exploiting the probability of their occurrence,
