Granulation of Sound in Video Games Granulation of sound for
games is becoming a more viable tool for sound artists as the
processing power of game consoles continues to improve.
Granulation is a relatively recent method of sound generation
which allows for sampled sound to be modified in real-time to
allow pitch to change independently of tempo among other audio
effects. It has not been commonly used with the previous
iterations of game platforms due to its relatively costly DSP
overhead and number of voices required. With the current
generation of game platforms, these limitations have been
relaxed allowing for the increased possibility of real-time
granulation in games. The combination of granulation and the
output of a game's physics engine is a promising relationship as
the physics engine can supply the large amount of real-time
control data for the grain parameters that granulation requires.
This paper investigates some current research in sound
granulation and demonstrates some effective methods of uti
