Constructor & Destructor Documentation

Filter::Filter ( )

Generic Filter class with scalable order and generic next_buffer method that implememnts the canonical filter diference equation. Subclasses must supply filter order and override the setupCoeffs() method.

Default constructor generates a zeroth order "do-nothing" filter

		unsigned	num_a = `1`
	)

References init().

Filter::Filter	(	UnitGenerator &	in,
		SampleBuffer	bCoeffs,
		SampleBuffer	aCoeffs,

	)

This constructor takes arrays of coefficients and constructs the filter accordingly.
