Transcendence Blade Vortex Effect

I know this is a common complaint but while I love the visuals of Transcendence Blade Vortex me and many others despise the sharp noise it makes on cast. Would there be a way to pitch down or plain remove the casting sound so it doesn't grate the ears after hours of playing?

Is there any update on this? I just bought the effect and i cant stand the sharp noise arround it. However i dont wanna tune down the sound effect volume since i wanna hear the explosions i do.
