How would you beat detect an audio file in Unreal?

I need to change the BPM of UMG images popping in and out based on classical music recorded without a click track.
Would it perhaps be possible to use sequencer with notifications, or even an animation sequence the same length as the song with Anim notifies?
Unless that synthesisia plugin has some features to do just that?
The method won’t matter, as long as it works.

This plugin could be useful for you. It has runtime beat detection: Audio Analysis Tools
