In previous versions of the program, information on speakers was set and phase differences were not taken into account. In EASE 4.0 Custom Speaker DLLs (Dynamic Link Libraries) allows designers to use proprietary information without divulging the techniques through a series of commands that are hidden via a black box with an input and output function.

Users can now simulate proprietary line arrays without the manufacturer having to release proprietary control information to the public, allowing them to change the parameters of those speakers for aim, distance and frequency, just like in real life.

The information afforded by the Custom Speaker DLLs is also incorporated into the balloon calculations so that the balloon of the line array can be simulated. This new set of data makes it possible to compute the Direct SPL (Sound Pressure Level) field for any speaker model or speaker DLL.

EASERA provides both data acquisition with a variety of stimulus signals including Time Delay Spectrometry, a sweep, a MLS or a noise excitation signal, and a post processing engine to calculate all acoustic functions or measures according to ISO Standard 3382 and higher.

The real time analyzer provides multiple ways to perform a fast on-site analysis or to obtain a precise view of the surrounding acoustic environment. Although many of these tools are available in one form or another in several products, EASERA is the first to bring them all together in one unified measuring package.

Now, thanks to EASERA, audio professionals can access the best features of all these measurement techniques from a laptop PC with a sound card.
