Allpass filter for introducting a 180 degrees phase shift at the center frequency. This is necessary for summing more than 2 bands created from Linkwitz-Riley filters. TODO: Inherit BiQuad directly to remove redundent code.
Process a sample that is passed to the processor, and return the next sample.
Should be used to free any delay elements or do any setup before play begins.
