Functions

DSP Feature Extraction

Extract DSP features from input data.

These functions perform digital signal processing (DSP) feature extraction (such as statistical or spectral features) from the input data. The extraction is performed according to the configuration in the neural network context.

Note: For models that do not require feature extraction, an empty implementation is provided.

Parameters

[in,out]	p_input	Pointer to the input processing context nrf_edgeai_input_t
[in,out]	p_dsp	Pointer to the DSP pipeline context nrf_edgeai_dsp_pipeline_t

Returns: Status code indicating success or error.
