Live sound and measurement seminars in the US
This fall, AFMG's distributor Renkus-Heinz and instructors Doug Fowler and Bruce Olson will be running a series of SysTune measurement workshops in the US. These two-day entry-level classes will provide an introduction into real-time measurements in live sound applications using EASERA SysTune.
The first class will be held in St. Louis, MO, on September 22nd/23rd.
AFMG and Renkus-Heinz are glad to have won live sound guru Doug Fowler as an instructor. Doug has been involved in measurement and alignment of portable systems since 1997. He has conducted dual channel FFT analyzer training numerous times over the last decade and is recognized internationally as an expert in concert sound reinforcement. Career highlights include numerous touring, large festival, and live DVD shoot credits as well as being published in trade magazines, and working in consulting capacities for several manufacturers. He is currently Director of Audio Engineering Services for Logic Systems Sound and Lighting, Inc. located in St. Louis, Missouri.
Most recently Live Sound International published a SysTune case study by Doug Fowler:
» Tuning a System Utilizing EASERA SysTune
AFMG and Renkus-Heinz also announce another two-day EASERA and SysTune measurement workshop in Lawrence, KS, on October 16th/17th. Instructors include Bob Coffeen, Jim Mobley and Bruce Olson as well as Stefan Feistel.
EASE Focus 1.62 released
This free update published on the 23rd of July includes the following changes:

Knowledge base
AFMG is proud to announce that recently another article on sound system modeling was published by the Journal of the AES.
It presents some of the theoretical background of the EASE GLL loudspeaker data format and offers an extensive overview of
its validation by measurement. The article was co-authored by Ambrose Thompson at Martin Audio.
» Methods and Limitations of Line Source Simulation by S. Feistel, A. Thompson and W. Ahnert. The authors are grateful for the support given by the R&D teams at Martin Audio and Kling & Freitag.
Live Sound International has recently published an introductory article about EASERA SysTune written by Charlie Hughes.
» Loudspeaker Measurements using EASERA SysTune
AFMG is thankful for the support given by its power user Charlie Hughes. He has been in the professional audio industry for over 20 years, having worked at Peavey Electronics and Altec Lansing. Charlie holds a Physics
degree from the Georgia Institute of Technology and currently runs Excelsior Audio Design & Services; a consultation, design and measurement services company based near Charlotte, NC.
Charlie Hughes has already written numerous papers about using AFMG's software products. Among them are:
- Loudspeaker directivity improvement modeled with EASE SpeakerLab
- Impedance measurements with EASERA
- Multi-channel loudspeaker polar measurements with EASERA
Also, AFMG and Charlie Hughes collaborated on the AES paper Simulating the Directivity Behavior of Loudspeakers with Crossover Filters. See Excelsior Audio for more.
