Hi,
Can you share the full script you’re using to pass the sound created with CoreSystem.createSound to the programmer sound?
Sounds made and played by the CoreSystem won’t be affected by any effects added in the FMOD Project. You’ll need to combine the ScriptUsageRecordMicrophone example with the Unity Integration | Scripting Examples: Programmer Sounds.
Check out this forum post where we discussed a similar issue: Adding Effects to Real-Time Recorded Audio.
Hope this helps!
