Additional Inherited Members
Protected Member Functions inherited from BaseIIRFilterReader
	BaseIIRFilterReader (std::shared_ptr< IReader > reader, int in, int out)
	Creates a new base IIR filter reader.
void	setLengths (int in, int out)

Constructor & Destructor Documentation

DynamicIIRFilterReader()

DynamicIIRFilterReader::DynamicIIRFilterReader	(	std::shared_ptr< IReader >	reader,
		std::shared_ptr< IDynamicIIRFilterCalculator >	calculator )

Creates a new DynamicIIRFilterReader.

Parameters

reader	The reader the filter is applied on.
calculator	The IDynamicIIRFilterCalculator that recalculates the filter coefficients.

Member Function Documentation

sampleRateChanged()

virtual void DynamicIIRFilterReader::sampleRateChanged ( SampleRate rate )

virtual

The function sampleRateChanged is called whenever the sample rate of the underlying reader changes and thus updates the filter coefficients.

Parameters

rate	The new sample rate.

Reimplemented from BaseIIRFilterReader.
