EASE JR was introduced in 1992 (2 years after the introduction of EASE) in response to numerous requests for a more basic Electro-Acoustic design and analysis program that cost less and Immediately became a favorite of system designers around the world.

EASE JR provides all the basic features and functions needed by most system designers, but does not include the in-depth acoustical analysis tools provided by EASE. A summary of EASE JR's capabilities follows.

1. EASE JR has the same extensive loudspeaker and wall material databases as EASE, including loudspeaker Dll's.

2. EASE JR has the same advanced and easy to use 3D modeling tools as EASE, including:

a. Room Prototypes
b. Create Shapes Function
c. The ability to create Objects

3. EASE JR has the same outstanding Open GL 3D rendering capabilities as EASE.

4. EASE JR has the same ability as EASE to import and export DXF files.

5. EASE JR has the same basic electro-acoustic mapping capabilities as EASE:

a. Direct SPL
b. %ALcons/Articulation Loss
c. RASTI
d. Pressure Levels
e. Clarity Ratios
f. Total SPL
g. D/R Ratio
h. Critical Distance
i. Arrival Times
j. Loudspeaker Overlap
k. ITD (Initial Time Delay) Gap
l. Loudspeaker Aiming

NOTE: EASE maps all the above measures on both Audience Areas (standard mapping) and on room surfaces (Faces). EASE JR maps all the above measures on Audience Areas, but can only map Direct SPL on room surfaces (Faces).

9. Basic Ray Tracing Capabilities*

*NOTE: EASE JR is limited to simple ray tracing of 3rd order reflections with 1000 rays/loudspeaker or fewer. This limits EASE JR to reflection studies that can be viewed in the View Project window. EASE JR cannot do any "Impact" ray tracing for specific seat locations, nor can it produce a virtual Room Impulse Response for acoustical evaluation. EASE ray tracing capabilities are not limited.

10. Acoustic Probe*

*NOTE: EASE JR does not have the Acoustic Probe. The Probe is a virtual measurement microphone that allows the EASE user to obtain detailed time, magnitude and frequency information for any point in an EASE map. The Probe is also used to view ray tracing impact files and to create virtual Room Impulse Responses for acoustical evaluation.
