At Sonic Bloom, we've been developing a proactive audio system, called Koreographer, that can achieve our dreams of dynamic, cinema quality game scores. It provides tools to create proactive-style data and APIs for the other game systems to consume it. A game armed with Koreographer gains awareness of the internals of the music mix which helps the game anticipate musical moments. We built it to naturally pair with reactive audio engines like Wwise and the combination of the two enables some amazing things. It’s the product of 10 years of Sonic Bloom’s collective history in music game companies. We began to build Koreographer out of the desire to change the way music is experienced in games: we want Raiders of the Lost Ark style scoring in Uncharted and believe that proactive audio will make this possible.
