Constructor & Destructor Documentation

◆ FFTBuffer()

FFTBuffer	(	uint	dataSize,
		EOverlap	overlap = `EOverlap::One`
	)

Parameters

dataSize	FFT buffer size
overlap	FFT buffer overlap

◆ ~FFTBuffer()

~FFTBuffer ( )

Member Function Documentation

◆ getAmplitudeSpectrum()

const AmplitudeSpectrum& getAmplitudeSpectrum ( )

Returns: normalized magnitudes (rho)

◆ getBinCount()

uint getBinCount ( ) const

Returns: the number of FFT bins

◆ getDataSize()

uint getDataSize ( )

Returns: the number of sample buffer data elements

◆ getPhaseSpectrum()

const PhaseSpectrum& getPhaseSpectrum ( )

Returns: normalized phase angles (theta)

◆ supply()

void supply ( const std::vector< float > & samples )

Update the internal sample buffer to perform FFT on. This funtion is thread-safe.
