AMPHIOTIK TECHNOLOGY
AMPHIOTIK ENHANCER is based on AMPHIOTIK TECHNOLOGY, which in turn is based on Binaural Technology. Binaural processing is based on HRTFs technique, a widely used method derived from the knowledge about perception of sounds by humans.

Virtual Worlds
The virtual environment is represented by the means of 3D-Graphics. New "worlds" can be generated through predefined templates. The dimensions of the world and the materials of the surfaces can be freely adjusted.

Sound Field Model (SFM)
SFM is simulated by the means of Image Source Method (ISM) for the early reflections, in combination with reverberation algorithms for the simulation of the late part. Ultimate control over the sound field is allowed, by selecting the material, and thus the absorption coefficients, of each surface.

Virtual Sound Sources (VSS)
There are five virtual sound sources, which are dynamically linked to the channels of the stereo input.

Positioning - 3D/2D View
Arbitrary positioning of the virtual sound sources (distance, azimuth and elevation) and virtual listener. This is easily accomplished through the 3D/2D View.

Listening over Headphones
When listening over headphones, the sound image is actually externalized out of the head.

Listening over Loudspeakers: Transaural-Audio (Cross-Talk Cancellation system)
When listening over loudspeakers, standard stereo makes the sound come from between the two speakers in front of the listener. Transaural-Audio extends the sound field beyond the separation of the loudspeakers and the sound surrounds the listener. Arbitrary positioning of the loudspeakers is allowed in the horizontal plane.

Absorption (screen-shot)
Materials database: stores the appearance and the absorption coefficients of materials.

Post equalization
Programmable low and high frequency filters allow to adjust the desired "shape" of the sound.

Gain Control
The overall gain can be automatically adjusted through the Automatic Gain Control (AGC).

Miscalleneous
Almost every parameter of the virtual auditory environment can be adjusted in real-time.

Individual HRTF (Head-Related-Transfer-Functions) support
AMPHIOTIK ENHANCER is shipped with with three sets of installable HRTFs based on data provided by a) CIAIR, Nagoya University, Japan, b) MIT Media Laboratory (HRTF Measurements of a KEMAR Dummy-Head Microphone, Bill Gardner and Keith Martin).
The format of the files containing the HRTF information is called ATHRTF (AMPHIOTIK TECHNOLOGY HRTF). Users have the capability to select different HRTFs for spatialization and cross-talk cancellation, a fact that furhter increases the flexibility of the program.

Storing
Load and save virtual environments and settings.

Commercial use
Commercial use is not allowed.
