ARRAY_PROPERTY()

fsk fft_dominant_frequency::ARRAY_PROPERTY ( struct fft_frequency_level_pair  , frequencies  , 0    )

pure virtual

Array of frequency pairs ordered by level (strongest first.

Convenience constructor (C++ only) This constructor is a varargs version of the default constructor allowing the inline specification of the frequency list (instead of using va_list). This constructor substitutes default values for all parameters if necessary.

Parameters

lrms	RMS level on the left channel (0)
rrms	RMS level on the right channel (0)
hi	High frequency (in Hz) to measure FSK percentage on (FSK_DEFAULT_HI)
lo	Low frequency (in Hz) to measure FSK percentage on (FSK_DEFAULT_LO)
fsk	FSK percentage of high frequency presence (0%)

References FFT_DOMINANT_NUMFREQ.

PROPERTY()

fft_dominant_frequency::PROPERTY	(	struct rms_strength	,
		rms
	)

overall RMS levels

FSK frequency comparison between low and high requencies
