Audio Synesthesia

I wonder if anyone can help me, I have made a Niagara system that reacts to any ambient sound in the level, this works great at runtime but when I try to record in sequencer it goes out of sync because the audio plays in realtime whereas the video take just over realtime to process some moments and everything goes out of sync. Is it at all possible for me to bake the audio so that it won’t go out of sync when recording, and if so, how on earth would I do it? Any help at all would be so very much appreciated
