Hi,
I am a bit confused on how code-words are derived from the codeword
lengths. I will appreciate if someone can point me in the correct direction.
I will take the example of an actual codebook that i found in a valid
vorbis encoded file as shown below.
[SK] +------Codebook [0] --------
[SK] Codebook Dimensions = 1
[SK] Codebook Entries = 8
[SK] Unordered
[SK] 1, 6, 3, 7, 2, 5, 4, 7,
[SK] NO Mapping
[SK] +------Codebook [1] --------
What are the correspnding codewords? I have written below a few, but I
think they might be wrong.
---------------------------
Entry len | Codeword |
---------------------------
1 | 0
6 | 100000
3 | 000
7 | 10000000
2 |
5 |
4 |
7 |
