I suggest you change these params:
array_frm_len
cfg_frame_len
AEC_REF_FIX_DELAY
and you can change the FFT length from here

@ shipleyxie
thank you very much，so we do not need to modify "subband_filter_coef" in dios_ssp_share_subband.c?

@shipleyxie
I modified what you maintioned, and also DELAY_BUFFER_SIZE to make sure it can run.
But the result is poor.
How can I modify it ?
