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:
FIRmaker, of course, has to obey the laws of physics. Priorities can be chosen e.g. between a substantial improvement in sound uniformity and maximum achievable SPL. Physics will always dictate a trade-off. However, FIRmaker usually provides far better optimizations within those limits than any conventional tuning could ever achieve.
FIRmaker FIR filters are non-symmetrical, complex-valued transfer functions. Despite their excellent performance they have a compact time behavior and a very smooth frequency response in both magnitude and phase. This, in turn, allows for implementation with a comparably low FIR tap count and low latency.
Currently, nearly every available DSP is capable of implementing the filters generated by FIRmaker.
FIRmaker does not generate linear phase filters. As such, the filters are not symmetrical in time about the peak of the filter’s impulse response. There is no requirement for the filters generated by FIRmaker to have pre-ringing. The transient behavior of the system will not be influenced.
Since AFMG FIRmaker is a technology that deeply influences the complete system behavior from the DSP block through limiting, amplification, crossover (or vice-versa) to each transducer, AFMG will implement the technology in close partnership with each loudspeaker manufacturer.
FIRmaker results are available in a few seconds. Simple setups typically require 2 to 10 seconds of computation time, complicated setups require 10 to 30 seconds.
These numbers are based on the performance of readily available laptops. Performance will probably be increased even more once specific implementations allow further customization of the underlying algorithms.
No, FIRmaker can also be used in loudspeakers equipped with on-board DSP. This applies for example to more sophisticated powered line arrays as well as to digitally steerable column loudspeakers.
In general, any possible combination of DSP / amplifyers / transducers within single or multiple cabinets or in a unified housing is possible as long as the hardware and DSP software allows storing of separate FIR filters into every DSP block.
Yes. AFMG FIRmaker only requires high-resolution loudspeaker modeling data as well as FIR processing capabilities. It will work with both, purpose-designed systems as well as existing products.
FIRmaker could even be applied to improve existing installations for better musical performance, increased speech intelligibility or higher signal-to-noise ratio.
No, FIRmaker is using high-resolution loudspeaker modeling data to simulate the performance of the system. Based on that FIRmaker computes optimal FIR filters for each DSP channel. Extensive tests in the field have shown that the accuracy of the simulation predicts system performance better than measurable differences of the real setup.
On-site measurements e.g. with SysTune or EASERA can, of course, be performed additionally to refine the performance and align the array to other parts of the sound system.

EASE has been vital to speech intelligibility design since the early ’90s, originally as a post-design evaluation tool. Many of us extended its use to explore electroacoustics, though meaningful iteration required inventive workflows and heavy setup.
Acousteer changes that. With real-time visual feedback on aiming, EQ, delay, and more, plus custom processing blocks, we now work as if we’re commissioning on site—only virtually. We can't hear it yet, but we can see the impact of every move, instantly and across the venue.
"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.”
