S. M. Audio Engineering utilizes and supports some of the most powerful loudspeaker engineering tools in the industry.
THE KLIPPEL ANALYZER SYSTEM is a tool for development and quality control of loudspeaker drivers and systems. It includes a large and growing suite of modules to measure, simulate, and investigate the loudspeaker performance objectively and assess the impact on the subjective listening impression. Download Dr. Klippel's latest paper on the nonlinear parameters, “ Loudspeaker nonlinearities - causes and symptoms”. You can also download a poster that summarizes this paper's conclusions. ARTA software (Audio Real Time Analysis) is an easy to use and well documented suite of programs for audio measurements and analysis. The ARTA program is a powerful analyzer for the measurement of frequency, step, and impulse responses, waterfall plots and sonograms, energy decay in reverberant environments, room acoustical parameters, directivity patterns, and speech intelligibility measures: MTF, STI, RASTI, %AL. The STEPS program enables the measurement of the frequency response with high dynamic range and high noise immunity. Simultaneously with a frequency response measurement, levels of harmonic distortion are also estimated. The LIMP program is for loudspeaker impedance measurements and the estimation of the Thiele-Small linear parameters. VECTOR FIELDS LTD. develops simulation software for the analysis and design of electromagnetic devices. The OPERA-2d and OPERA-3d packages are used by leading companies, research laboratories, and universities throughout the world. We did an advertisement for them. You can download SM Audio Engineering's BH Curves for the OPERA packages. For a limited time we are offering indefinite licenses to Bl(x,i).comi and Le(x,i).comi proprietary command files and one-year free support including sample problems to any company or individual that purchases a license for OPERA from S. M. Audio Engineering. LspCAD6 is loudspeaker design and modeling software for the professional designer. It includes box modeling and modeling for active and passive crossovers, and can emulate aural crossovers in real time. LOUDSOFT has a variety of loudspeaker simulation applications which all utilize very user-friendly graphical user interfaces. User up-to-speed time is typically hours, not days or weeks. FINECone is a convenient and powerful application for performing natural frequency FEA. FINEMotor can be used with the users' Electromagnetic FEA application such as VF OPERA to obtain quasi-dynamic large signal simulations. FINEBox and FINE X-over facilitate a virtual loudspeaker coupled with the outputs from FINEMotor and Cone. Software and support are available from S. M. Audio Engineering. Soft-Part LAB is a powerful Finite Element Analysis software application that has a nonlinear geometry model with composite (multi-laminate) material property capability. It is utilized for large signal simulation and buckling analysis of high performance spiders and surrounds along with natural frequency simulation of cone and dome vibration modes. DIGMODA is a state of the art plate amplifier with ICE Power modules and DSP on board. The DSP functions and filtering are implemented with D-PRO Windows software with a user-friendly graphic interface. What most companies do with resistors, capacitors, and op-amps, DIGMODA does with software! MAGONITE is a new experimental ceramic material that is manufactured by applying proprietary KERONITE processes to pre-formed Magnesium foil for extended periods of time to obtain MgO ceramic cones and dust caps. Brush-Wellman Electrofusion Beryllium Domes and Truextent Assemblies are the world’s finest high frequency diaphragms. Actually they are the only supplier of Beryllium foil on the planet. Don’t be fooled by misleading claims of “Beryllium” transducers that contain 10% Beryllium or less. Discount priced samples of acoustic grade Beryllium (98% or better) domes and assemblies are available to S. M. Audio Engineering’s active clients.
FRIENDS AND INDUSTRY COLLEAGUES:
US PATENT SEARCH: Search the US Patent Database for patents granted in the past two months in the classes of 181 and 381 that have the words "loudspeaker", "speaker", "transducer" or "diaphragm" in the title. Search the Pre-grant US Patent Application Database for patent applications published in the past two months in the classes of 181 and 381 that have the words "loudspeaker", "speaker", "transducer" or "diaphragm" in the title. Google Patent Advanced Search can also be used to search the USPTO database. AlternaTIFF may be required to view the patent images. AlternaTIFF is a web browser add-on (ActiveX control or plug-in) that displays most of the common types of TIFF image files. It works in most web browsers for Windows 95 or higher (98, ME, NT4, 2000, XP, etc.).
