The result, EASERA, was released in late 2004. Its first goal was the development of a new software-based measurement platform that would unify all existing approaches in a modern format. SDA Software Design Ahnert GmbH was founded in 1999. The growing availability of both desktop and laptop computing power, along with increased demand for modular extensions to the EASE software suite, led to the decision to form a new company in order to put the software development on a professional basis. EASE 3.0 was released in 1999 as the first version of EASE to run in the more user-friendly Windows environment. Stefan Feistel joined the development team in 1995 to port EASE to the Windows operating system. The rapid acceptance of EASE by professional acousticians and sound system designers encouraged the development team to expand the program’s functionality and refine its accuracy, leading in 1994 to the last release for MS-DOS – EASE 2.1. Shortly thereafter, Renkus-Heinz became the worldwide distributor of the English-language version. EASE was first introduced to the professional audio industry in 1990 at the 88th AES Convention in Montreux. The previously-developed software prototype was given a functional interface and a now-familiar name: EASE (Electro-Acoustic Simulator for Engineers). Soon after the Berlin Wall fell in 1989, ADA Acoustic Design Ahnert was founded. Feistel contributed both advanced calculation algorithms and user interface programming. Ahnert applied his thorough theoretical training and practical experience in acoustics to design the software concepts. Rainer Feistel, Professor of Theoretical Physics at Rostock University, to develop a computer program capable of scientifically simulating the Delta Stereophony concept. After scientific studies at Lomonossov University in Moscow, he teamed up with Dr. Wolfgang Ahnert realized the importance of accurate acoustical design and analysis software. Through his work with AKG on the Delta Stereophonic System, Prof. ADA (Acoustic Design Ahnert) & SDA (Software Design Ahnert)Īhnert Feistel Media Group (AFMG) originated in the late 1980’s.
