#include <include/nrf_edgeai/dsp/transform/fft/nrf_dsp_fft_f32.h>

The floating-point complex FFT function with custom radix function to use.

Parameters

[in]	p_cfft	Pointer to instance of complex FFT structure nrf_dsp_cfft_f32_t
[in,out]	p_input	Pointer to buffer with input samples, the FFT computes in-place and will modify input buffer with FFT results. The results will be written to input array in the interleaved fashion: {real[0], imag[0], real[1], imag[1], ...}
[in]	bitreverse_flag	Flag that enables (bitreverse_flagR=1) or disables (bitreverse_flagR=0) bit reversal of output
[in]	radix_func	Custom FFT Radix function to compute FFT, refer to nrf_dsp_cfft_radix8by2_f32, nrf_dsp_cfft_radix8by4_f32 or nrf_dsp_cfft_radix8_f32
