AkAbak is a professional simulation program for electro-mechano-acoustical networks running under Windows (TM). The simulation is carried out on lumped elements and one-dimensional waveguide components.
It is especially intended for the investigation and design of loudspeaker systems. AkAbak simulates a complete system: from the voltage source through to any listening point - including all filters, networks, radiation elements and the nearby radiation environment.
The philosophy behind the program is to provide a simple, easy-to-use framework, even for complicated and extensive systems. The structures that are to be analyzed can be custom-built from standard elements, or for a speedy and efficient simulation, compact modules can be used. There are unlimited possibilities for interconnecting the individual modules, so that even exotic designs can be simulated.
The program as a whole is designed to emulate the principles of loudspeaker design as closely as possible. One consequence of this is that all the parameters required by the models simulating the structures are easy to obtain or to measure. Computation is very fast, so that it is possible to use a trial-and-error method, or to investigate the effects of component tolerances. The superb accuracy of the simulation provides a sound basis for testing out design ideas or for dimensioning and matching the components of an electrical, acoustic or electroacoustic design.
Apart from its simulation functions, AkAbak also includes a range of CAD tools, such as synthesis of passive networks with dissipative coils, tools for bass speaker design, filter design, etc. The classical simulation method of lumped elements is one of the most powerful and approved tools in designing and investigating electro-acoustic devices. AkAbak makes the application most convenient and efficient.
The idea of AkAbak was born in 1991. From the beginning the intention was to have available the technique of lumped elements in a most flexible way. The program was directly designed for the Windows platform. In 1994 the first version of AkAbak was released. The possibility of free and easy modeling the electro-acoustical domain was welcomed by the industry. The good response encouraged us to present AkAbak at the AES convention in Paris 1994, which was a great success. Thanks to the feedback of our customers AkAbak improved constantly, papers were given and more exhibitions followed.
