1. A method of encoding audio data frequency coefficients, the method comprising:

  • receiving a sequence of audio data frequency coefficient symbols, wherein the sequence includes a run and an adjacent symbol, the run including R symbols each having a first value, and the adjacent symbol having a value L other than the first value;

    looking up the sequence within a data structure that assigns a corresponding entropy code to the sequence based jointly upon the values for R and L for the sequence; and

    outputting the corresponding entropy code for the sequence.
