class FilterAnalyzer

Measures properties of a filter, like frequency/impulse response, gain, or delay.

Public functions

void Dispose()	Free the resources used by this analyzer.
Constructor FilterAnalyzer(Filter filter, int sampleRate)	Copy a filter for measurements.
Complex[] GetFrequencyResponse()	Get the frequency response of the filter.
ReadOnlyCollection<Complex> GetFrequencyResponseReadonly()	Get the frequency response of the filter.
float[] GetSpectrum()	Get the absolute of FrequencyResponse up to half the sample rate.
ReadOnlyCollection<float> GetSpectrumReadonly()	Get the absolute of FrequencyResponse up to half the sample rate.
void Reset(Filter filter)	Change the filter while keeping the sample rate.
void Reset(Filter filter, int sampleRate)	Change the filter and the sample rate.
Equalizer ToEqualizer(double startFreq, double endFreq, double resolution = 1 / 3f, int oversampling = 1)	Render an approximate Equalizer by the analyzed filter's frequency response.

float Delay	Response delay in seconds.
float Gain	Maximum filter amplification.
float GainDecibels	Maximum filter amplification in decibels.
float[] ImpulseResponse	Filter impulse response samples.
bool Polarity	Filter polarity, true if positive.
int Resolution	Used FFT size for most measurements.
int SampleRate	Sample rate used for measurements and in filter if it's sample rate-dependent.
