Disabling/shortening keyboard shortcut animations for volume control

As stated in the question title, I'd like to know if there's a way to disable or shorten the animations that occur when I press keys F10, F11 and F12 to control volume.

I've been searching around for a while in pursuit of an answer, but I haven't found anything that specifically relates to this.

I assume that this would be accomplished using the 'default' command in terminal, but I can't seem to figure out what domain this animation belongs to.

Any suggestions or alternatives are welcome too. Thanks!
