Spell sounds on high animation speeds

Some sound effects of spells last more, than spell animation itself, when adjusting higher battle animation speed. Causing a mess of sounds and animation. "Holy Shout" spell, for example, has long lasting sound effect, and on high speeds animations, finishes at the time sound is still in process, We've already met same problem with teleport spell. #681 In the OG spell animation seemed not to effect by battle speed adjustment. How do we make up with this issue? Shall we take away dependency of battlespeed and spell animations? Or can we speed up spell animation, till the moment, sound finishes? Or can we speed up sounds of spells together, with spell animation? If we decide to speed up spell animation, we can use two last proposals together.
