Functions
flt32_t	nrf_dsp_freq_snr_f32 (flt32_t p_amplitude_spectrum[], uint16_t num, uint16_t p_freq_indicies[], uint16_t freq_indicies_num)
	Compute signal-to-noise ratio for provided frequencies in floating-point amplitude spectrum, signal represent provided frequencies, noise is everything else.
int16_t	nrf_dsp_freq_snr_i16 (int16_t p_amplitude_spectrum[], uint16_t num, uint16_t p_freq_indicies[], uint16_t freq_indicies_num)
	Compute signal-to-noise ratio for provided frequencies in fixed-point amplitude spectrum, signal represent provided frequencies, noise is everything else.
