The raid sound that the goat's horn makes doesn't match the animation at all. Animation and sound exist completely separately. In my opinion, the animation should continue until the sound ends (or almost ends).
Steps to reproduce:
- Take the goat's horn.
- Change the view to third person from the front.
- Start using the goat horn and look at the player (at yourself in the game).
Animation and sound are completely separate.
The sound will match the animation.
