GameCODA

GameCODA is an audio middleware product by Sensaura designed for game developers to create realistic sound environments in video games. It allows development for the following platforms: PC, Xbox/Xbox 360, Sony PlayStation 2 and Nintendo GameCube. It uses several environmental audio technologies developed by Sensaura.

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 plattforms. It cannot edit audio assets itself apart from sample rate, channels and size; you need an audio editor for much 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 are available for Maya and 3D Studio Max.

Environmental audio technologies

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

HRTF positioning of sources

Digital Ear

To create realistic HRTFs, Sensaura created their own artificial head system for measuring. From that they created a table of over 1000 pairs of filter characteristics with associated time delays, each representing one unique point in 3D space. HRTFs from these Digital Ears are incorporated into our Sensaura 3D-sound algorithms.

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 a very accurate cancellation signal.

ensaura MacroFX

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

ZoomFX

ZoomFX is 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.
