A generic filter component allows, among other things, for the modeling of LP/HP filters of various filter order, pole-zero or directform filters imported from eg.

A paradigm that makes the initial prototype modeling simpler is the parameter mode that allows the user to modify parameters such as crossover frequency and Q value rather than having to fiddle with component values. For well-known box types a special wizard functionality helps the user to pick an optimal alignment for the given driver, each radiating part of a loudspeaker can be linked to a baffle component that makes it possible to model baffle diffraction and reflections from the closest walls in a listening roomĬrossovers that can be implemented are besides analog pass and active filters also digital filters with unit delays and sum units. The boxes are designed with building blocks such as ports, cabinet volumes and driver units. Moreover a number of filter templates are available some of them with wizard functionality which makes it easy to tune the components for desired properties Another concept that simplifies designs is the group concept where one can simply group a number of components and later with a simple mouse click change on one set of component values to another set and see the results of the changes instantly. Additionally a set of Store/Recall buttons makes it easy to make rapid comparisons of different designs. To alleviate this potential problem, the concept of network sets is implemented. This allows for a large degree of freedom for the user, on the downside is the problem that the design procedure may become more tedious. there is no need to do box modeling first and crossover modeling later, this makes prototyping of new projects easier.Ĭrossovers and boxes are created from a tray of components, the components are picked from the tray and dropped of the schema. With LspCAD 6 it is possible to model loudspeaker boxes, passive crossovers, active analog and digital crossovers.Ī nice feature is that it is possible to model everything at the same time, i.e. LspCAD6 professional, the full version with all features enabled.
