Some echo sound sets are missing frequencyRandomizer parameter, this is couses 'robotic' sound glitch for tail sounds which with weaponShotTailDistanceFreqAttenuationFilter distance filter:

Apparently, having a value above zero for the frequencyRandomizer parameter is mandatory for echo sounds which using weaponShotTailDistanceFreqAttenuationFilter distance filter
check pasteBin CfgSoundSets to see how to fix it (see only param in right from each distanceFilter=""; rest is vanilla non-changed data)
Minor glitch hearable when high caliber machine guns shoot
Medium glitch hearable when shots autocannons
Major glitch hearable when shots coaxial machineguns and miniguns (7.62, 6.5 mm)
