AFMG Reflex: Get Diffusion Right
German software developer AFMG, renowned for mathematically rigorous acoustical simulations, has developed a new tool for designers and owners of project studios and home theaters. AFMG Reflex is the first commercial software to model the reflection, diffusion, and scattering of sound waves by geometrical structures.
Reflex Basic owners can quickly and easily analyze both specialized diffusers and ordinary wall surfaces. Reflex Basic saves time and money by optimizing diffusing room treatments for small to mid-sized critical listening spaces. Users can quickly evaluate diffuser performance and fine-tune room design for both single-listener and expanded “sweet spots.”
“Diffusors can reduce standing waves and smooth out room response while keeping a live quality,” points out AFMG’s Stefan Feistel. “But they’re more expensive than simple absorption, and until AFMG Reflex, the results were extremely hard to predict.”
Although it is based on unique advanced algorithms, Reflex Basic makes design and optimization simple and easy. The user draws a two-dimensional cross-section of the reflective surface. Reflex Basic then displays the reflective properties as a polar response graph for any frequency at any angle of incidence. Scattering and diffusion coefficients are shown as frequency response graphs. Different angles and frequencies can be compared and saved as a report. This makes it easy to optimize both the design of diffusers and their placement in the room.
Along with Reflex Basic, AFMG has introduced Reflex Standard, which has an unlimited feature set.
“With Reflex Standard, acoustical consultants and architects can finally move beyond rule-of-thumb estimates of scattering coefficients,” Feistel says. “Scattering coefficients computed by Reflex Standard can be exported directly into EASE wall material files to improve simulations significantly, especially when modeling acoustically challenging environments.”
In Reflex Standard, the size and complexity of surfaces are unlimited: Any 2D-extruded geometrical surface design can be modeled. Users can view multiple surface models simultaneously for detailed comparison. AFMG Reflex Standard is an indispensable tool for calculating the scattering coefficients that are required for auralizations (audible previews of sound system performance and architectural acoustics) generated by the EASE module AURA.
AFMG will distribute both versions of Reflex online through www.afmg.eu
Multi-user licenses for both programs are available at a 20% discount. Trial versions of AFMG Reflex can be downloaded from the product website http://reflex.afmg.eu which also provides detailed information about both Reflex Basic and Reflex Standard.
