makeHighPass() [1/2]

template<typename NumericType >

static std::array< NumericType, 6 > dsp::IIR::ArrayCoefficients< NumericType >::makeHighPass ( double sampleRate, NumericType frequency )

static

Returns the coefficients for a high-pass filter.

static

Returns the coefficients for a notch filter.

makeNotch() [2/2]

static

Returns the coefficients for an all-pass filter.

makeAllPass() [2/2]

template<typename NumericType >

makeLowShelf()

template<typename NumericType >

static std::array< NumericType, 6 > dsp::IIR::ArrayCoefficients< NumericType >::makeLowShelf ( double sampleRate, NumericType cutOffFrequency, NumericType Q, NumericType gainFactor )

static

Returns the coefficients for a low-pass shelf filter with variable Q and gain.

The gain is a scale factor that the low frequencies are multiplied by, so values greater than 1.0 will boost the low frequencies, values less than 1.0 will attenuate them.

makeHighShelf()

template<typename NumericType >

static std::array< NumericType, 6 > dsp::IIR::ArrayCoefficients< NumericType >::makeHighShelf ( double sampleRate, NumericType cutOffFrequency, NumericType Q, NumericType gainFactor )

static

Returns the coefficients for a high-pass shelf filter with variable Q and gain.

The gain is a scale factor that the high frequencies are multiplied by, so values greater than 1.0 will boost the high frequencies, values less than 1.0 will attenuate them.

makePeakFilter()

template<typename NumericType >

static std::array< NumericType, 6 > dsp::IIR::ArrayCoefficients< NumericType >::makePeakFilter ( double sampleRate, NumericType centreFrequency, NumericType Q, NumericType gainFactor )

static

Returns the coefficients for a peak filter centred around a given frequency, with a variable Q and gain.

The gain is a scale factor that the centre frequencies are multiplied by, so values greater than 1.0 will boost the centre frequencies, values less than 1.0 will attenuate them.
