With this post I’m taking a slight diversion away from low-level DSP and plug-ins to share a fun little experimental project I just completed. It’s a game of Tic-Tac-Toe using the FMOD sound engine with audio based on the minimalist piano piece “Für Alina” by Arvo Pärt. In the video game industry there are two predominant middleware audio tools that sound designers and composers use to define the behavior of audio within a game. Audiokinetic’s Wwise is one, and Firelight Technologies’ FMOD is the other. Both have their strengths and weaknesses, but I chose to work with FMOD on this little project because Wwise’s Mac authoring tool is still in the alpha stage. I used FMOD’s newest version, FMOD Studio.
The fun and interesting part of this little project was working with the fairly unusual approach to the audio. I explored many different ways to implement the sound in a way that both reflected the subtletly of the original music while reacting to player actions and the state of the game. Here is a video demonstrating the result. Listen for subtle changes in the audio as the game progresses. The behavior of the audio is all based on a few simple rules and patterns governed by player action.
The game is available for download (Mac OS X 10.7+ only).
