the 68K limitation I removed last 20 entires from the rq_table.dat.Will this work w/o these entires,atleast a garbage output.

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.
