. 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 platforms. 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

Environmental audio technologies

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

Digital Ear

To create realistic HRTF

Head-related transfer function

A head-related transfer function is a response that characterizes how an ear receives a sound from a point in space; a pair of HRTFs for two ears can be used to synthesize a binaural sound that seems to come from a particular point in space. Some consumer home entertainment products designed to...

s, 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.

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.
