Abstract
The target of this work is the high quality audio coding at low bit rate. It is shown how pyramid vector coding (PVC) can conveniently replace the classical Huffman coding technique in audio compression systems, providing also an advantage in the bit allocation procedure. The compression performances can be further improved by fixing an upper limit value to the vector components
