[ATTACH=CONFIG]196468.vB5-legacyid=4913[/ATTACH]Berlin, Germany, September 25, 2012 – AFMG’s prime measurement software SysTune finally achieves accolades for years of scientific research and development. Patents in the US and Germany have been granted to AFMG for their Real Time Deconvolution technology. Further patents are pending. Real Time Deconvolution algorithms are the significant factor in SysTune’s unrivaled performance at impulse response processing. No other audio measurement software is able to deliver full-length impulse responses and other measurement data derived from them in real time.
“An impulse response,” explains Stefan Feistel, managing director of AFMG, “contains all the information that can be derived from the measurement of a linear, time-invariant system, such as loudspeaker systems, rooms and the like. Magnitude and phase transfer functions can be extracted from an impulse response just as all parameters of electro and room acoustics. In order to evaluate STI, RT, C50 or many other parameters of room acoustics, you need to have a full-length impulse response – and SysTune is the only software able to deliver this in real time.”
Developers at AFMG have been working on the topic of room impulse responses for three decades. With the rise of computer processing power, SysTune has been the first real-time audio measurement program to deliver fluent, continuous and reliable results without the need for error-prone, manual delay tweaking. Refinement of SysTune’s astute algorithms led to the filing of the patents in 2007. Now, in 2012, AFMG can celebrate: Quality and uniqueness of SysTune have been officially approved and patented by national authorities!
[ATTACH=CONFIG]196469.vB5-legacyid=4914[/ATTACH][B]Full-length Impulse Reponses – The Key to Quality Measurements[/B]
What makes the real-time processing of full-length impulse responses so special and important? As you know, any measurement that is not full-length will not contain all the information necessary to describe the acoustic conditions of the system under test. Imagine measuring in a large hall during a concert. Everybody knows you will need to use live audio with a dual-channel FFT to do the job. Few people, however, know that each measurement cycle needs to be as long as the complete decay of sound in the room in order to fully describe it. SysTune´s patented algorithms are the only ones able to perform such measurements and calculations in real time. Many other approaches either lose information or cannot be performed in real time. With SysTune you can do system tuning and reliable evaluation of room acoustics and speech intelligibility in real time during your event.
[B]More Features in SysTune 1.2[/B]
AFMG has recently released a free upgrade to SysTune, giving users access to more very interesting new features. The Web Interface for remote control from virtually any modern smartphone or mobile device has been celebrated among SysTune users as a big time-saver. The helpful Delay Analysis plug-in provides exceptional power to users with little experience in setting up sub / top or main / delay systems while opening a wide range of extra opportunities to professional system technicians.
When taking into account that SysTune is still within version 1.x and all previous upgrades have been free, users can be very excited by what more there is to come!

[B]Background Information:[/B]
EASERA and SysTune – A Pair for all Requirements in Audio Measurement
AFMG´s EASERA is the universal software platform for all acoustical, electronic, and audio technical measurements. It fulfills the highest scientific demands. Beyond that, it has features that allow quick and comprehensive gathering of data in the field which can then be analyzed in depth when back in the office. EASERA has all established measurement signals ready in one coherent and easy-to-learn platform thus providing a multitude of options for measuring and evaluation.
Professionals worldwide value SysTune as the preferred software platform when it comes to analyzing and optimizing sound systems in operation. For this, SysTune provides multi-channel measurements in real time, giving sound engineers precise impulse and frequency responses, as well as delay times – even in the middle of the show with an audience present.
[B]EASE – Industry Standard for Acoustical Simulation of Rooms[/B]
Since the 1990´s, EASE has been setting the worldwide standard for acoustic simulation both inside rooms and in open areas. Rooms can be defined using a CAD module, absorption coefficients can be assigned to surfaces, and sound sources as well as listener positions can easily be added to the model. Data can then be used to generate an exact simulation of reverberation times, speech intelligibility and other acoustical parameters even before the room itself is built.
This is also very useful especially for predicting the performance of loudspeaker models in a suggested acoustical environment. EASE supports this by providing the most extensive loudspeaker database available on the market. EASE SpeakerLab assists loudspeaker manufacturers in continually providing new data in GLL format. SpeakerLab is frequently implemented by more and more manufacturers, and the GLL format provides possibilities to define loudspeakers and controllers in all their parameters. This is singular to the market; EASE continues to be unrivaled in ease of use, flexibility and precision in simulating electro- and room acoustics.
In 2011 AFMG has expanded the EASE suite of programs by two more remarkable tools. AFMG SoundFlow simulates absorption, reflection, and transmission of sound by multi-layered structures. AFMG Reflex can model the reflection, diffusion, and scattering of a sound wave hitting any 2D structured surface. Both programs provide an immense increase to the accuracy of acoustical simulations by enhancing the wall materials used in EASE.
