The Freetar Editor is a closely related project that allows users to create songs for Freetar from songs on their computers - allowing a near unlimited number of songs.
Note: I was forced to discontinue work on Freetar due to a conflict of interest when I was hired by Activision.

This program is a tool designed to assist players in the game WWII:OL (also known as "Battlefield Europe") in setting the correct range for the infantry mortar. It (when provided with accurate coordinates for the player and target) will calculate the appropriate range.
It uses the windows speech-recognition engine so that you can enter coordinates from the in-game map verbally without having to type them. Also it makes you feel like a badass shouting out mortar coordinates.
