In hq_ecu_fx(), there is a classification to select a concealment method. One of the parameters used for the classification is `hHQ_core->env_stab_plc_fx`, which is compared against a threshold. In EVS decoding, there is ``` NE_16( hHQ_core->env_stab_plc_fx, 0 ) ``` In IVAS decoding, there is ``` GT_16( hHQ_core->env_stab_plc_fx, 16384 ) /* 0.5 in Q15 */ ``` This looks like a wrong threshold value is used in EVS. <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them. Add further information to the first row and remove and add labels as necessary.-->
