A video with vanilla example of a weapon whose sound set has the correct value will be very useful I think → https://youtu.be/G6Ttod9sGPs
Watch the video, this is the class LMG65mmBody_tail_SoundSet, its vanilla value is frequencyRandomizer=1; and this is correct, there is no glitches in the echo sound. Let's change the value to 0, and then glitches appears, same glitches as for sound set classes ​​where in the table column from ticket description «has frequencyRandomizer param ?» has "no"
Same we can do with e.g. Rifle_Tail_Base_SoundSet, then most rifles will have same glithes

To complete ensure of problem, all classes in the table have the same sound3DProcessingType and weaponShotTailDistanceFreqAttenuationFilter values:

• sound3DProcessingType="WeaponMediumShotTail3DProcessingType";
• distanceFilter="weaponShotTailDistanceFreqAttenuationFilter";

and classes where: frequencyRandomizer=0; will glitched - (value 0 by default if this parameter is not written at all)

Please look at this doc: BIKI ExampleWeaponConfig - CfgSoundSets
Pay attention to TAG_Your_Rifle_Tail_SoundSet, you can make sure that all tail sounds should have the frequencyRandomizer parameter greater than 0 — tails plays overlap each other, different sound frequency allow to get rid of glitch.

Please, add frequencyRandomizer parameter to the classes from the table in the ticket description.
