#In order to support DRC AMD-2(ISO/IEC 23003-4:2020/Amd. 2:2023(E)), `leveling_present` and `ducking_only_set` fields are introduced in DRC config file.
#For a given DRC effect, when both `leveling_present` and `ducking_only_set` are set to 1, automatically the next drc instruction is treated as ducking only set.
#For example, if the second DRC effect is marked as 2048/4096 with  `leveling_present` is set to 1 and `ducking_only_set` is set to 1, then the third DRC effect will be treated as ducking-only.
#For the last drc instruction, `leveling_present` and `ducking_only_set` fields are ignored and reset to 0. Maximum supported instructions are 8.
