Detailed Description

ADEC output structure.

Member Data Documentation

◆ delay_change_request_flag

int32_t adec_output_t::delay_change_request_flag

Flag indicating if ADEC is requesting an input delay correction

◆ delay_estimator_enabled_flag

int32_t adec_output_t::delay_estimator_enabled_flag

Flag indicating if AEC needs to be run configured in delay estimation mode.

◆ requested_delay_samples_debug

int32_t adec_output_t::requested_delay_samples_debug

Requested delay samples without clamping to +- MAX_DELAY_SAMPLES. Used only for debugging.

◆ requested_mic_delay_samples

int32_t adec_output_t::requested_mic_delay_samples

Mic delay in samples requested by ADEC. Relevant when delay_change_request_flag is 1. Note that this value is a signed integer. A positive requested_mic_delay_samples requires the microphone to be delayed so the application needs to delay the input mic signal by requested_mic_delay_samples samples. A negative requested_mic_delay_samples means ADEC is requesting the input mic signal to be moved earlier in time. This, the application should do my delaying the input reference signal by abs(requested_mic_delay_samples) samples.

◆ reset_aec_flag

int32_t adec_output_t::reset_aec_flag

flag indicating ADEC's request for a reset of part of the AEC state to get AEC filter to start adapting from a 0 filter. ADEC requests this when a small delay correction needs to be applied that doesn't require a full reset of the AEC.
