Function Documentation

fft_find_bin()

int fshift::fft_find_bin	(	mha_real_t	frequency,
		unsigned	fftlen,
		mha_real_t	srate
	)

Finds bin number of FFT bin nearest to the given frequency.

Parameters

frequency	The frequency for which to look. Has to be in range [-srate/2,+srate/2]
fftlen	Length of the FFT.
srate	Sampling rate of the waveform from which the FFT originates.

Returns

Bin number of the FFT bin corresponding to frequency
