Turn Pitch Shift Sounds Off?



On Gratuitous Tank Battles I was wondering if there’s a way to turn off Pitch Shift Sounds.
You could do this in Gratuitous Space Battles in the options menu.

The reason I was wondering, is I like to play at a slower speed; both because it’s more comfortable, and it feels more epic.
But at slower speeds the sound pitches lower, so soldiers shouting sounds very deep and slow, as well as the other sfx like lasers, machineguns, etc.

I was looking in the config files, but all I see is sound height falloff, which is currently set to 0.75; not sure what that does.
