I’m on the same issue.
Instead of delay I’m using Concatenator in a SoundCue. There’s a HUGE seam.
Of course, my audio files are perfectly seamless (thay are cuts 1 and 2 of the same file) and “Prime on load” is checked for de SoundCue.
What I’m tryng to do: I have an audio file for a RC plane. First5-6 recording secs is the engine starting up, then it keeps stable for a minute.
SO I split that recording to two different files “engine start.wav” and “engine loop.wav” and create a SoundCue that plays the start once and the concatenates to the loop (looping).
So easy, but it’s not working. Huge sound stop at the concatenation.
So, Bump!
