Ken, I've addressed your comments.  I've also fixed an issue where the filter coefficients (m_b1 and m_b2) were being used with negative values from what is normally used in biquad filter difference equations.  I've negated their use both in the processing math and when the coefficient values are calculated, so overall there is no change mathematically, but the code now looks cleaner and is in a more standard form.
