Located in Berlin, Germany, AFMG® Technologies GmbH has created the industry standards EASE and EASERA software for acoustic simulation and measurement as well as their related products EASE Focus, AFMG SysTune, EASE Address and EASE SpeakerLab.

In cooperation with our partner company SDA Software Design Ahnert GmbH we develop and distribute software for:

Electro-acoustic and
room-acoustic modeling
Electronic and acoustic

Applications in
engineering and physics
RF and infrared
simulation

Why does the SPL Column in Loudspeaker Properties for a GLL or DLL show 0 (zero) dB or less?

Before EASE actually calculates the response of a certain loudspeaker defined in a GLL or DLL, the program does not know anything about the sensitivity or maximum input voltage the manufacturer entered within the GLL/DLL. Therefore, neither the sensitivity, frequency response, nor the maximum input can be displayed in the user interface.

We are a loudspeaker company. Do you have measurement guidelines for creating loudspeaker data files in GLL format?

Accurate loudspeaker data is necessary for reliable simulation results.

As a manufacturer you can measure and create loudspeaker data yourself. In addition to the proper equipment, you would need in-depth knowledge about the measurement techniques to adequately model the loudspeaker behavior. For this please refer to SpeakerLab’s comprehensive User´s Guide which can be found under the link below.

In this manual you will find step-by-step instructions for the most common cases along with related references:

We are a loudspeaker company. How can we add our data to EASE ?

Adding your data to the EASE® loudspeaker database is free of charge. It requires collecting selected loudspeaker performance data and converting it in a binary format.

Acoustic, electronic and mechanical data of the sound source must be assembled in a single data file, the so-called GLL. This GLL file can also include your logo and company information.

How do I use my User Keys with multiple computers?

In general, AFMG® grants to you the right to use our software programs on a specific number of computers. This number corresponds to the number of User Keys you have purchased. More specifically, one User Key  can be used only by one user on one machine at any particular point of time.

The following rules need to be considered when the software program is provided to different users within a company or to partners:
