CAGE Producer

CAGE Producer is the central audio asset management tool which bundles the sound samples into sample banks, sound banks and reverb banks for the target console platforms. It cannot edit audio assets itself apart from sample rate, channels and size; an audio editor is needed for anything more than that. It communicates with the CAGE plugins for positioning of sound and reverb environments on the basis of the 3D geometry. The CAGE plugins were available for

Audio technology

Sensaura 3D Positional Audio (S-3DPA)

Using HRTF and detailed positioning of sound sources, GameCODA can create aurally accurate 3D audio environments. For more information, see Sensaura 3D Positional Audio

3D speaker technology

XTC (Transaural Crosstalk Cancellation)

XTC algorithm which tries to reduce acoustic crosstalk. It uses both the distance and angle of the loudspeakers to calculate precisely the transaural crosstalk level and then generates an appropriate cancellation signal. For more information, see Sensaura 3D speaker technology

Environmental audio technologies

Sensaura developed different technologies to create a more realistic audio environment for the listener:

MacroFX

MacroFX is an algorithm that tries to create realistic close-up effects.

ZoomFX

ZoomFX was a technology for simulating the sound of large emitters. This is achieved by creating each virtual sound area from several, similar, virtual point sources, rather than from a single point source, as is commonly done.

EnvironmentFX

EnvironmentFX technology models different acoustic environments allowing the generation of early reflections and reverberation, in order to produce an immersive 3D audio environment. Not just with sounds themselves, it also factors in the acoustic contribution of the environment.
