The function as it is was more or less a hack, it should probably use
the table from the datasheet so the mixer would respond to something
resembling db, more or less like the bass/treble controls ( yes, typing
them in will be a pain in the arse, I meant to do it at some point -
it's probably time now since the mixer controls actually became useful )

have fun
