Auralquiz is a simple music quiz game that uses your own music files. It plays short pieces of music files from your folders and presents a question and several answers about the current song. The faster the answer, the more points you receive. Up to eight people can play in a turn-based mode. In the highest difficulty level, instead of having the buttons, the player must type the answer. Symbols like "!", "-", "." etc are filtered out, and it's not case sensitive, so it's a little easier to answer correctly.
