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

Calculate Spectral Spread in floating-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

flt32_t Spectral Spread
