| Introduction |
| The process of loudspeaker crossover design is complex, involving both measured data along with mathematical components, all combined within a circuit simulator. Moreover, both electrical as well as acoustical computations and references must be maintained throughout the process in order to obtain accurate acoustical and electrical results. Traditional circuit simulators merely handle electrical components and lack the needed features to properly handle the unique requirements of this mixed environment. |
| CrossoverShop features a proprietary electroacoustic simulator with highly specialized components, offering all of the capabilities necessary for advanced crossover design and analysis. It allows a procedural design flow methodology, rather than trial & error analysis, or the more time consuming, iterative, and expensive method of build and test. A multitude of different crossover designs can be simulated, examined, and refined in a fraction of the time required to construct and measure a single physical design. |
| CrossoverShop computes all of the electroacoustic response curves automatically and plots them on an assortment of different graphs, each controlled by a full featured scale system. A graphical schematic editor is also provided for circuit construction and editing. Over two dozen extensive synthesis tools turn nearly any filter idea into instant reality. |
| A detailed treatment of the many subjects within the software would be far beyond the scope and space limitations of this brochure. Rather it will define and explain some of the more significant capabilities and features offered by CrossoverShop to design systems of many different types, structures, and complexity. With CrossoverShop, designing great crossovers has never been easier! |
| Application Software |
| The main program screen is shown below. CrossoverShop is a large Win32 program and contains over 100 dialogs, extensive 2D graphics, a wide assortment of post processing utilities, and intensive numerical mathematics. Over 80 specialized Windows® custom controls were created for the program. All simulations are performed utilizing both frequency and time domain analysis. Many of the numerical floating point routines are written in 80x87 assembly language and were highly optimized using the Intel® VTune™ Performance Analyzer to maximize FPU performance and minimize analysis time. All computations are performed with either Double (64bit) or Extended (80bit) floating point precision. |
