Member Data Documentation

◆ adaption_config

aec_adaption_e coherence_mu_config_params_t::adaption_config

Filter adaption mode. Auto, force ON or force OFF

◆ coh_alpha

float_s32_t coherence_mu_config_params_t::coh_alpha

Update rate of coh.

◆ coh_slow_alpha

float_s32_t coherence_mu_config_params_t::coh_slow_alpha

Update rate of coh_slow.

◆ coh_thresh_abs

float_s32_t coherence_mu_config_params_t::coh_thresh_abs

Adaption frozen if coh below coh_thresh_abs.

◆ coh_thresh_slow

float_s32_t coherence_mu_config_params_t::coh_thresh_slow

Adaption frozen if coh below (coh_thresh_slow*coh_slow)

◆ eps

float_s32_t coherence_mu_config_params_t::eps

Parameter to avoid divide by 0 in coh calculation.

◆ force_adaption_mu_q30

int32_t coherence_mu_config_params_t::force_adaption_mu_q30

Fixed mu value used when filter adaption is forced ON

◆ mu_coh_time

unsigned coherence_mu_config_params_t::mu_coh_time

Number of frames after low coherence, adaption frozen for.

◆ mu_scalar

float_s32_t coherence_mu_config_params_t::mu_scalar

Scalefactor for scaling the calculated mu.

◆ mu_shad_time

unsigned coherence_mu_config_params_t::mu_shad_time

Number of frames after shadow filter use, the adaption is fast for

◆ thresh_minus20dB

float_s32_t coherence_mu_config_params_t::thresh_minus20dB

-20dB threshold

◆ x_energy_thresh

float_s32_t coherence_mu_config_params_t::x_energy_thresh

X_energy threshold used for determining if the signal has enough reference energy for sensible coherence mu calculation
