LspCAD 6 is a software intended for the
design of loudspeaker boxes and crossovers. With LspCAD 6 it is possible
to model loudspeaker boxes, passive crossovers, active analog and
digital crossovers. A nice feature is that it is possible to model
everything at the same time, i.e. there is no need to do box modeling
first and crossover modeling later, this makes prototyping of new
projects easier.
Crossovers
and boxes are created from a tray of components, the components are
picked from the tray and dropped of the schema. 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. To alleviate this potential
problem, the concept of network sets is implemented. Additionally a set
of Store/Recall buttons makes it easy to make rapid comparisons of
different designs. 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. 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
The
boxes are designed with building blocks such as ports, cabinet volumes
and driver units. 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 room
Crossovers
that can be implemented are besides analog pass and active filters also
digital filters with unit delays and sum units. 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. 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. Matlab or Octave, digital BiQuad filters, FIR filters, also a
digital equalization filter component makes it possible to invert the
frequency response of a given loudspeaker unit in order to achieve a
ruler-flat response in the driver working range.
Components for well-known commercial digital filters such Behringer, dbxPro and XTA is implemented and also optimized.
To
be able to achieve a given target frequency response a powerful
crossover optimizer can be used. This optimizer also gives the option to
put constraints on things such as component values and resulting load
impedance, the unique feature of the load impedance optimization is that
it actually can increase the load impedance while maintaining the
desired frequency response. Another feature is that one may lock the
crossover frequency during the optimization.
The
tolerance analysis helps to give a view of how the resulting frequency
response of a crossover deviates from the original response once we add
the possibility that components might deviate from their specified
values.
Finally the powerful crossover emulator (or auralizer) is a good companion when it comes to evaluating crossovers.
The
popular real time update feature in LspCAD 6 gives the user a "What you
see is what you get" feeling as the graphs are updated each time one
change e.g. a component value. Similar to earlier releases it is
possible to store intermediate work. |
