Constructor & Destructor Documentation

IIRCoefficients() [1/3]

juce::IIRCoefficients::IIRCoefficients ( )

noexcept

Creates a null set of coefficients (which will produce silence).

IIRCoefficients() [2/3]

juce::IIRCoefficients::IIRCoefficients ( double c1, double c2, double c3, double c4, double c5, double c6 )

noexcept

Directly constructs an object from the raw coefficients. Most people will want to use the static methods instead of this, but the constructor is public to allow tinkerers to create their own custom filters!

IIRCoefficients() [3/3]

juce::IIRCoefficients::IIRCoefficients ( const IIRCoefficients & other )

noexcept

Creates a copy of another filter.

~IIRCoefficients()

juce::IIRCoefficients::~IIRCoefficients ( )

noexcept

Destructor.

Member Function Documentation

makeAllPass() [1/2]

IIRCoefficients juce::IIRCoefficients::makeAllPass ( double sampleRate, double frequency )

staticnoexcept

Returns the coefficients for an all-pass filter.

makeAllPass() [2/2]

IIRCoefficients juce::IIRCoefficients::makeAllPass ( double sampleRate, double frequency, double Q )

staticnoexcept

Returns the coefficients for an all-pass filter with variable Q.

makeBandPass() [1/2]

IIRCoefficients juce::IIRCoefficients::makeBandPass ( double sampleRate, double frequency )

staticnoexcept

Returns the coefficients for a band-pass filter.

makeBandPass() [2/2]

IIRCoefficients juce::IIRCoefficients::makeBandPass ( double sampleRate, double frequency, double Q )

staticnoexcept

Returns the coefficients for a band-pass filter with variable Q.

makeHighPass() [1/2]

IIRCoefficients juce::IIRCoefficients::makeHighPass ( double sampleRate, double frequency )

staticnoexcept

Returns the coefficients for a high-pass filter.

makeHighPass() [2/2]

IIRCoefficients juce::IIRCoefficients::makeHighPass ( double sampleRate, double frequency, double Q )

staticnoexcept

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

makeHighShelf()

IIRCoefficients juce::IIRCoefficients::makeHighShelf ( double sampleRate, double cutOffFrequency, double Q, float gainFactor )

staticnoexcept

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.

makeLowPass() [1/2]

IIRCoefficients juce::IIRCoefficients::makeLowPass ( double sampleRate, double frequency )

staticnoexcept

Returns the coefficients for a low-pass filter.

makeLowPass() [2/2]

IIRCoefficients juce::IIRCoefficients::makeLowPass ( double sampleRate, double frequency, double Q )

staticnoexcept

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

makeLowShelf()

IIRCoefficients juce::IIRCoefficients::makeLowShelf ( double sampleRate, double cutOffFrequency, double Q, float gainFactor )

staticnoexcept

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.

makeNotchFilter() [1/2]

IIRCoefficients juce::IIRCoefficients::makeNotchFilter ( double sampleRate, double frequency )

staticnoexcept

Returns the coefficients for a notch filter.

makeNotchFilter() [2/2]

IIRCoefficients juce::IIRCoefficients::makeNotchFilter ( double sampleRate, double frequency, double Q )

staticnoexcept

Returns the coefficients for a notch filter with variable Q.

makePeakFilter()

IIRCoefficients juce::IIRCoefficients::makePeakFilter ( double sampleRate, double centreFrequency, double Q, float gainFactor )

staticnoexcept

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.

operator=()

IIRCoefficients & juce::IIRCoefficients::operator= ( const IIRCoefficients & other )

noexcept

Creates a copy of another filter.
