## Detailed Description

template<typename NumericType>
struct juce::dsp::FIR::Coefficients< NumericType >

A set of coefficients for use in an FIRFilter object.

  FIRFilter

Definition at line 220 of file juce_FIRFilter.h.

## Member Typedef Documentation

## ◆ Ptr

template<typename NumericType >

using juce::dsp::FIR::Coefficients< NumericType >::Ptr = ReferenceCountedObjectPtr<Coefficients>

The Coefficients structure is ref-counted, so this is a handy type that can be used as a pointer to one.

Definition at line 240 of file juce_FIRFilter.h.

## Constructor & Destructor Documentation

## ◆ Coefficients() [1/3]

template<typename NumericType >

juce::dsp::FIR::Coefficients< NumericType >::Coefficients | ( |  | ) |
| inline

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

Definition at line 224 of file juce_FIRFilter.h.

## ◆ Coefficients() [2/3]

template<typename NumericType >

juce::dsp::FIR::Coefficients< NumericType >::Coefficients | ( | size_t | size | ) |
| inline

Creates a null set of coefficients of a given size.

Definition at line 227 of file juce_FIRFilter.h.

## ◆ Coefficients() [3/3]

template<typename NumericType >

juce::dsp::FIR::Coefficients< NumericType >::Coefficients | ( | const NumericType * | samples,
|  | size_t | numSamples
| ) |  |
| inline

Creates a set of coefficients from an array of samples.

Definition at line 230 of file juce_FIRFilter.h.

## Member Function Documentation

## ◆ getFilterOrder()

template<typename NumericType >

size_t juce::dsp::FIR::Coefficients< NumericType >::getFilterOrder | ( |  | ) | const
| inline noexcept

Returns the filter order associated with the coefficients.

Definition at line 244 of file juce_FIRFilter.h.

## ◆ getMagnitudeForFrequency()

template<typename NumericType >

double juce::dsp::FIR::Coefficients< NumericType >::getMagnitudeForFrequency | ( | double | frequency,
|  | double | sampleRate
| ) |  | const
| noexcept

Returns the magnitude frequency response of the filter for a given frequency and sample rate.

## ◆ getMagnitudeForFrequencyArray()

template<typename NumericType >

void juce::dsp::FIR::Coefficients< NumericType >::getMagnitudeForFrequencyArray | ( | double * | frequencies,
|  | double * | magnitudes,
|  | size_t | numSamples,
|  | double | sampleRate
| ) |  | const
| noexcept

Returns the magnitude frequency response of the filter for a given frequency array and sample rate.

## ◆ getPhaseForFrequency()

template<typename NumericType >

double juce::dsp::FIR::Coefficients< NumericType >::getPhaseForFrequency | ( | double | frequency,
|  | double | sampleRate
| ) |  | const
| noexcept

Returns the phase frequency response of the filter for a given frequency and sample rate.

## ◆ getPhaseForFrequencyArray()

template<typename NumericType >

void juce::dsp::FIR::Coefficients< NumericType >::getPhaseForFrequencyArray | ( | double * | frequencies,
|  | double * | phases,
|  | size_t | numSamples,
|  | double | sampleRate
| ) |  | const
| noexcept

Returns the phase frequency response of the filter for a given frequency array and sample rate.

## ◆ getRawCoefficients() [1/2]

template<typename NumericType >

const NumericType * juce::dsp::FIR::Coefficients< NumericType >::getRawCoefficients | ( |  | ) | const
| inline noexcept

Returns a raw data pointer to the coefficients.

Definition at line 272 of file juce_FIRFilter.h.

## ◆ getRawCoefficients() [2/2]

template<typename NumericType >

NumericType * juce::dsp::FIR::Coefficients< NumericType >::getRawCoefficients | ( |  | ) |
| inline noexcept

Returns a raw data pointer to the coefficients.

Definition at line 269 of file juce_FIRFilter.h.

## ◆ normalise()

template<typename NumericType >

void juce::dsp::FIR::Coefficients< NumericType >::normalise | ( |  | ) |
| noexcept

Scales the values of the FIR filter with the sum of the squared coefficients.

## Member Data Documentation

template<typename NumericType >

Array<NumericType> juce::dsp::FIR::Coefficients< NumericType >::coefficients
