Bit Coding

The quantized coefficients are coded using an individual Huffman table for each band. The string of coefficients are encoded one by one until the last nonzero coefficient, where a separate Huffman table stores the number of zeros in the end of the block. The Huffman tables are not published here for the reason that they have not been fixed yet. In the coder experiment program, the Huffman trees are created dynamically based on information from the processed signal.
