left channel starts at byte 229 and the right channel at byte 269, (each of the EQ bands using 4 bytes) and the left and right use up through bytes 268 and 308. These are probably the actual band definitions, more on that shortly.

Ok, so it looks like the 4 bytes decodes thus at each db setting in a band:
+12db to 94578288
+11db at 84286808
+5db at 42224896
+4db at 37630220
0db to 23736102
-1db to 26634296
-2db to 29886364
-3db to 33527318
-4db to 37630220

But the only indicator of + versus - db seems to be the simple index in bytes 169-178 and 179-188, and those are literal, so I don't understand what the point of these are. I don't know enough about equalizer application to know what this might be for. Comments anyone?
