There is another possibility in addition to Grigory's suggestion,  
although it will result in reduced accuracy.

The table size can be reduced from 32K to 4K by exploiting the  
following equality:

     (8 x)^(4/3) = 16 x^(4/3)

Specifically, when x ≥ 1024, x^(4/3) can be calculated by:

     16 (x/8)^(4/3)

Thus the table size can be reduced to 4K (for entries 0-1023), at the  
expense of a loss of audio quality due to the error introduced by the  
integer division.
