I just had this thought while brushing my teeth :

I havn't yet taken into consideration the frequency responce of the SPL meter (an important step). I'm sure the SPL meter automatically adjusts for a flat curve, but I doubt that it goes from 20Hz to 20kHz. The default empeg bands range from 50Hz to 18kHz. If those two outer bands are no detectable by the SPL meter, mayb we can remove them and then slide them all down "to the left" to free up bands 9 and 10?

I'm off to work now, so I don't have time to look into the specs of the meter, but they are available online if anyone wants to check while I'm away. Otherwise, I'll do it when I get home.
