    102102This block key is "AB".[[BR]]
    103103This block contain audio frames. The first frame is a key frame.[[BR]]
     104
    104105The seek elements allow to jump back or forward. The block size can be used to seek 1 block forward.[[BR]]
    105 
    106 Seek block nb should be ( - means offset is negative) :[[BR]]
    107 2 -2 3 -3 2 -2 4 -4 2 -2 3 -3 2 -2 5 -5 2 -2 3 -3 2 -2 4 -4 2 -2 3 -3 6 -6 2 -2 ...[[BR]]
    108 so 2 -> 2, 3 -> 3 ... and -2 -> -2, -3 -> -3 ...[[BR]]
    109 Allow to seek back and forward in O(ln(n)) time without a seeking table. It's something like [http://www.cipr.rpi.edu/~pearlman/papers/EI05_fastaccess_ycp.pdf this paper][[BR]]
     106Allow to seek back and forward in O(ln(n)) time without a seeking table. Have to find something like [http://www.cipr.rpi.edu/~pearlman/papers/EI05_fastaccess_ycp.pdf this paper][[BR]]
