Since its introduction in 1990, EASE has grown from a single program into a family of sophisticated electro/acoustic simulation programs and associated program modules.

The EASE family now includes:

EASE, the Electro-Acoustic Simulator for Engineers, was developed by Dr Ahnert of ADA (Acoustic Design Ahnert) to answer the industries need for a more accurate acoustic design and analysis program than was currently available. Over the years, it has become widely known for the accuracy of its predictions and is now widely accepted as the Industry Standard electro-acoustic design and analysis program.

Developed specifically for the system designer who doesn’t need all the advanced acoustic analysis features of EASE, EASE JR has become the favorite of hundreds of system designers worldwide. It provides all the modeling and simulation capabilities needed by most designers and at a much lower cost than EASE. Check it out; you’ll be surprised at everything it does.

EARS, Electronically Auralized Room Simulation, adds subjective listening to the list of evaluation tools available to professional designers. It allows you to listen to how a room and its associated loudspeaker system will sound, even before the room is actually built.
EARS is a Binaural auralization program whose auralizations are inherently more realistic than monaural auralizations.

EARS RT 4.1
EARS RT is the “Real Time” version of EARS. It uses Lake convolution filters to produce binaural auralizations in an ongoing manner that can be listened to almost immediately. The 4.1 version adds the ability to auralize stereo signals to its many features.

AURA, Analysis Utility for Room Acoustics, a relatively new member of the EASE program module family, allows calculations of acoustic parameters with exceptional accuracy and speed. Based upon the Caesar algorithms developed by the scientists at the University of Aachen, Germany, the AURA module adds advanced acoustic analysis tools to the impressive list of EASE features.

AURA also features the ability to include Diffusion in its simulations.

VISION
VISION, a program module introduced along with EASE and EASE JR 4.0, adds the ability to create photo realistic models to the extensive list of EASE and EASE JR features.

VISION allows the addition of lights and lighting effects (shading and shadows) to the room and “Textures” to the surfaces. With Textures surfaces can, for example, be made reflective, shiny, and transparent or turned into solid brick or stone walls. The result is renderings that are unbelievably realistic.

IR (Infrared) Module
The IR module is another new addition to the EASE and EASE JR family of programs. It allows the performance of Infrared systems to be simulated and analyzed in the same fashion loudspeaker systems are simulated and analyzed.

EASEVIEW
EASEVIEW is a stand alone program supplied with EASE and EASE JR. It can be installed on any PC and used to view and manipulate Open GL files. It allows EASE and EASE JR users to give a copy of the EASEVIEW program to their clients, so their clients can view EASE and EASE JR open GL files on their computers without having to own EASE or EASE JR.
