nrf_dsp_spectral_spread_i16()

int16_t nrf_dsp_spectral_spread_i16	(	int16_t	p_spectrum[],
		uint16_t	num,
		nrf_dsp_spectral_ctx_i16_t *	p_ctx )

#include <include/nrf_edgeai/dsp/spectral/nrf_dsp_spectral_spread.h>

Calculate Spectral Spread in INT16 fixed-point spectrum.

Parameters

[in]	p_spectrum	Pointer to amplitude spectrum vector
[in]	num	Number of bins/samples in amplitude spectrum
[in,out]	p_ctx	Pointer to optional spectral context, the calculated value of magnitude_sum and cetroid will be used

Returns

int16_t Spectral Spread
