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:
In EASERA almost any evaluation and measure can be derived directly or indirectly from loaded or measured impulse response data. The same is true for most of the intelligibility measures.
EASERA allows for calculating STI, STI (Male), STI (Female) as well as AlCons and the equivalent STIPa. Note that these values are all calculated from the modulation transfer function (MTF), which in turn originates in the impulse response.
Yes, it can.
EASERA implements a new method of measuring nonlinearities in the response of a system. By utilizing a pink sweep as an excitation signal, all of the distortion components are located at the end of the impulse response and can be separated by windowing.
After some post-processing the individual harmonic frequency responses can be viewed and even THD in a high frequency resolution can be computed. Of course also the K2, K3 K.. spectra are available.
There are basically three native file formats available in EASERA: EMD, ETM and EFR.
EMD is a time domain format that also saves the raw measurement data. Generally this is recommendable to use during measurement sessions as it allows for later inspection of the actually recorded raw input data.
The ETM contains the IR data only, but it is otherwise identical with the EMD. It is useful if you are not interested in keeping the raw data or if you just want to save some overlay files.
Yes, it is possible to use an external stimulus signal with EASERA.
Using an external generator can be specified in the Select Measurement Setup Window. Please choose
Dual Channel > More > Compare Inputs via the Select Setup Button.
For 1/3rd Octave Band Resolution
To calculate reverberation times (RT) for frequencies lower than 100 Hz in 1/3rd octaves, you need to apply a filter to the broadband Transfer Function. There are two ways to apply this filter.
Option 1: Applying the Filter Manually
First please install the latest version of the Lake Controller. Then run the AFMG SysTune setup in order to remove and reinstall SysTune.
This will then enable the SysTune plugin for the Lake Controller.
If you have installed the Digidesign ASIO driver, this can cause the problem.
Extract the file from the attached zip below and place it in the folder where "SysTune.stcfg" is located. For your computer that is C:\Users\<user>\AppData\Local\AFMG\EASERA SysTune (<user> is your log-in name).
This will disable the Digidesign ASIO driver in SysTune only.
In general, all modern audio interfaces have a very high probability of working fine with SysTune. To make use of more than the primary two channels please make sure, that your device is supplied together with a current ASIO driver.
If you like to be sure that your existing hardware can be used in conjunction with our software, we suggest registering for a free 30-day trial version.
Yes, this is possible although AFMG does not recommend it. You need to understand the following background information and proceed with the instructions below to transfer your SysTune User Key between the different environments.
The licensing engine used by AFMG SysTune sees Boot Camp and a virtual machine as different computers.
To use one license under both environments the license has to be migrated from Boot Camp to the virtual machine or vice-versa.
In EASE SpeakerLab create a new project for a "Subwoofer" type loudspeaker:
"EASE 5 is a big step forward. The completely new user interface combined with lots of useful tools and further improved simulation modules allow for much more intuitive and effective workflows."
“We are currently using EASE 4 in our company and I must say I'm very happy with the changes in EASE 5. The workflow is much faster and more intuitive.”
“EASE 5 provides swift simulation preparation, seamless integration with SketchUp, and visually stunning results, which make it perfect for creating high-quality reports. Its user-friendly design ensures a seamless experience for beginners and professionals, making it a valuable asset for your acoustic simulation needs.”
“EASE 5 is a game changer offering easy to use, intuitive tools and modern workflows. Not only is the ability to import a 3D DWG into EASE 5 out of Vectorworks Spotlight a huge time-saver, but it keeps the consistency throughout all of my engineering programs and allows me to deliver stunning visual content of acoustics and loudspeakers analysis alike, in both 2D and 3D, that every one of my clients can easily understand.“
“Thanks to the AFMG Team for being “agile” with this new version of EASE. It’s reassuring to see that AFMG is taking the user’s feedback into account and continuously upgrades its software with top voted remarks. There has been a lot of new upgrades in few months since the first version that I get, and everything is going on the good direction!”
“Congratulations to the AFMG team for excellent work on EASE 5 so far! The new technology and approach is highly appreciated, visualization and UX is great!”
“EASE 5 makes it easy to create audience areas and align loudspeakers. You can easily orientate yourself in the model at any time, which not only helps when working on the project but also enables a clear presentation for customers.”
“We’re happy to rely on EASE 5 as efficient tool for standard-conform STI and RT calculations. This is how we support the technical planners and architects in an efficient and cost-saving way.”
“EASE 5 greatly simplifies the process of creating and navigating around a 3D model. I was able to quickly learn the new interface and create predictions to help us design a system, and help the customer visualize the end-product.”
