30 * Optimal huffman decoding for AAC taken from:
31 * "SELECTING AN OPTIMAL HUFFMAN DECODER FOR AAC" by
32 * VLADIMIR Z. MESAROVIC , RAGHUNATH RAO, MIROSLAV V. DOKIC, and SACHIN DEO
33 * AES paper 5436
34 *
35 * 2 methods are used for huffman decoding:
36 * - binary search
37 * - 2-step table lookup
38 *
39 * The choice of the "optimal" method is based on the fact that if the
40 * memory size for the Two-step is exorbitantly high then the decision
41 * is Binary search for that codebook. However, for marginally more memory
42 * size, if Twostep outperforms even the best case of Binary then the
43 * decision is Two-step for that codebook.
44 *
45 * The following methods are used for the different tables.
46 * codebook "optimal" method
47 * HCB_1 2-Step
48 * HCB_2 2-Step
49 * HCB_3 Binary
50 * HCB_4 2-Step
51 * HCB_5 Binary
52 * HCB_6 2-Step
53 * HCB_7 Binary
54 * HCB_8 2-Step
55 * HCB_9 Binary
56 * HCB_10 2-Step
57 * HCB_11 2-Step
58 * HCB_SF Binary
