2a62b38530 Update filter histories even when they're not used 
If the filter properties are continually updated, and the HF or LF gain goes
from <1, to 1, and later back to <1, the history shouldn't hold stale values
from before it was at 1.

48aa1e10d6 Use the high-shelf filter in place of low-pass 
They effectively both work to lower (or raise) high frequencies. However, the
high-shelf performs better when gain=1.
