Description

Sound Synthesis in CRACKDOWN 2 and Wave Acoustics for Games
SPEAKER/S: Nikunj Raghuvanshi (Microsoft Research)
DAY / TIME / LOCATION: Friday 2:00- 3:00 Room 3010, West Hall 3rd Fl.
TRACK / FORMAT: Audio / Lecture
DESCRIPTION: Present-day game audio technology is almost entirely based on using preset sound banks and reverb filters. These techniques require tedious effort and have a hard time handling the sheer variety of situations that can arise during a game. A natural solution is physics-driven sound.

This talk will consist of a discussion of two techniques:
Firstly, a physics-based procedural sound synthesis technique that was used in CRACKDOWN 2. A procedural model for an impact sound is extracted from its recording which is then used to synthesize a near-unlimited variety of subtle variations at runtime, eg. varied footsteps from a single footstep sound.

Secondly, a novel technique for sound propagation in games that uses precomputed wave simulation on game maps to handle scene-dependent effects such as smooth loudness reduction on occlusions/obstructions, sound scattering, sound focusing and realistic reverb.

TAKEAWAY: The talk will focus on two physics-driven sound techniques. Firstly, a novel technique for procedural sound synthesis that was used in CRACKDOWN 2. The technique can synthesize variations for impact sounds on the fly, by extracting the procedural, physically-based model from a single sound clip. Secondly, a wave-based sound propagation technique that can automatically compute environment-dependent acoustic effects such as obstruction, focusing, scattering and reverberation.
INTENDED AUDIENCE: Anyone interested in game audio. People with a physics background will enjoy it too, as this talk will be an interesting mix of audio and physics. Prerequisites knowledge: Very little will be assumed beyond a firm grasp of basic math. Understanding of signal processing and/or physics will help, but is not necessary.
