Detailed Description

Class to use an FFT Implementation.

This manage the instantiation and initialization of an FFT algorithm to be used into subclasses. It use the AudioFFT library so the implementation is chosen at compile time setting the right flag.

Member Function Documentation

FFT()

void pdsp::FFTWorker::FFT	(	const float *	inSignal,
		float *	re,
		float *	im
	)

performs FFT

Parameters

[in]	inSignal	signal to process (time domain)
[out]	re	real part output (frequency domain)
[out]	im	imaginary part output (frequency domain)

iFFT()

void pdsp::FFTWorker::iFFT	(	float *	outSignal,
		const float *	re,
		const float *	im
	)

performs iFFT

Parameters

[out]	outSignal	signal output (time domain)
[in]	re	real part input (frequency domain)
[in]	im	imaginary part input (frequency domain)
