New EASE Tools Go Beta

AFMG is proud to announce the Beta cycle for a set of new modeling programs related to room acoustics and building acoustics as well as to EASE and EASE AURA.

AFMG SoundFlow AFMG SoundFlow is a newly designed software for simulating sound propagation in multi-layered walls. Based on the physical properties of the building materials and the configuration of the wall structure it calculates the absorption coefficient and reflection coefficient as well as the transmission loss for all frequencies and angles of incidence.

Another tool expanding the capabilities of the EASE software and its modules is the new AURA-Remote program. As a plug-in to EASE it allows all AURA users to speed up their calculation times by orders of magnitude using the remote server farm of AFMG.

AFMG Reflex

Last but not least, AFMG finally publishes the software AFMG Reflex to calculate the scattering of sound waves incident on a structured surface or diffusive geometry.

For more information please see our detailed announcement.

EASE (China) Opens Measurement Lab

Jack Sui Headed by Xing (Jack) Sui and located in Hong Kong, EASE (China) will now provide loudspeaker measurement services. All measurements are conducted with a high degree of accuracy utilizing an anechoic chamber in Beijing as well as a sophisticated turning robot manufactured by the German company Four Audio and AFMG's professional measurement software EASERA.


Immediately after its opening, the measurement laboratory resumed its work. A set of Beta Three loudspeakers manufactured by the Chinese company Elder Audio is currently being measured. The resulting loudspeaker data files are verified and then added to the EASE database.

Knowledge base

The newly developed, patent-pending spectrally selective accumulation (SSA) filter by AFMG provides a robust means to make accurate measurements in noisy environments or when using speech or music excitation signals. An impressive demo was prepared by Doug Fowler and is located here:

Recently, our Beta user Charlie Hughes wrote a detailed article about all-pass filter designs. He used our software packages SpeakerLab and EASERA extensively. This paper was published in the Voice Coil magazine issue 2/2010.

Spring Classes Review

We would like to provide a brief review of the most recent workshops run by AFMG, Renkus-Heinz and Markus Zehner.

The last EASE class held in Berlin from April 28th-30th, was sold out and all participants enjoyed three days of advanced EASE content, meeting with the developers and establishing new contacts to other professionals. Instructor Emad El-Saghir said: "It was my pleasure teaching this class. It had an exceptionally high level due to the great working knowledge and experience of the participants. We did not even have to touch the basics anymore."

Recent System Engineering classes and SysTune Measurement workshops run by Markus Zehner were also very well received. Especially the new 4-day Sound System Engineering course was warmly welcomed by the community due to its hands-on layout and the inclusion of simple sound system design studies.

As often, this May's EASE class hosted and run by Renkus-Heinz, CA, USA, was completely sold out. For participants from all over the country these entry-level classes taught by Jim Mobley and Jonas Domkus provide a great opportunity to gain professional knowledge and learn how to use EASE within a short time frame.

After 2008, this year AFMG was again present at AES Brazil. Instructor Bruce Olson conducted several training classes and workshops. The interest in EASE, SysTune and other programs was very high so that all classes were well attended.
