Steps to Reproduce
WITH SOUND EFFECT CHAIN:
- Create a sound effect source preset chain

WITH META SOUND:
- Create new metasound source
- Add wave player mono with looping wave asset (preferably)
- Add “Delay (Time)” node
- Add UE.Attenuation interface to metasound interfaces
- Add Distance (UE.Attenuation) node
- Divide distance by 34000 (speed of sound in cm/s)
- Plug result in Delay Time (auto converts to time)
- Click on distance node and set range max to 5000
Play the sound in metasound editor and move the Distance knob
OR
Put sound in the world and move around
