IC adaption controller configuration structure. More...
#include <ic_state.h>
IC adaption controller configuration structure.
This structure contains configuration settings that can be changed to alter the behaviour of the adaption controller. This includes processing of the raw VAD probability input and optional stability controller logic. It is automatically included as part of the IC state and initialised by ic_init().
The initial values for these configuration parameters are defined in ic_defines.h.
| uint8_t ic_adaption_controller_config_t::enable_adaption |
Boolean which controls whether the IC adapts when ic_adapt() is called.
| uint8_t ic_adaption_controller_config_t::enable_adaption_controller |
Boolean which controls whether Mu is automatically adjusted from the VAD input.
| uint8_t ic_adaption_controller_config_t::enable_filter_instability_recovery |
Boolean which controls whether to enable detection and recovery from instability in the case when the adaption controller is enabled.
| fixed_s32_t ic_adaption_controller_config_t::energy_alpha_fast_q30 |
Fast alpha used filtering input and output energies of IC.
| fixed_s32_t ic_adaption_controller_config_t::energy_alpha_slow_q30 |
Slow alpha used filtering input and output energies of IC.
| float_s32_t ic_adaption_controller_config_t::instability_recovery_leakage_alpha |
Setting of H_hat leakage which gets set if fast ratio exceeds a threshold.
| float_s32_t ic_adaption_controller_config_t::leakage_alpha |
Alpha used for leaking away H_hat, allowing filter to slowly forget adaption.
| float_s32_t ic_adaption_controller_config_t::out_to_in_ratio_limit |
Ratio of the output to input at which the filter will reset. Setting it to 2.0 is a good rule of thumb.
| float_s32_t ic_adaption_controller_config_t::voice_chance_alpha |
Alpha used for low pass filtering the voice chance estimate based on VAD input.
