Description: ABACUS (A Box and Crossover User-friendly Simulation
Software) is a simple Microsoft Windows-based program to
help the DIY speaker builder to plot out the frequency
response curves for vented cabinets. The responses of up to
four user defined cabinets can be simultaneously seen,
allowing easy what-if comparisons. The "Keele Alignment"
for box volume and tuning frequency is calculated
automatically and its frequency response can be plotted.
Another alignment called the "Mehta Alignment" is also
offered as a starting point in the search for the ideal
cabinet volume. The port calculator allows easy design of
the port dimensions. The formulae used for calculating
frequency response are those used in "Keele's Pocket
Calculator" method. The crossover design section has not
yet been implemented in version 2.0 of the software. All
speaker driver parameters box volume and vent tuning
combinations entered by the user are stored in a file for
later reuse.

Name: CALE (Computer Aided Loudspeaker Engineering)
Computer: MS-DOS
Distributor: ELAC Technische Software GmbH
Prices: CALE-Demo, 23 DEM (approx. US$14)
CALE Light, for private use 99 DEM (approx. US$61)(CD-ROM)
CALE full version for private use, 805 DEM (approx. US$495)
CALE full version for commercial use, 2415 DEM (approx. US$1486)
Description: CALE is available in several "steps," the above full
versions includes step I, step II and expansion A, but an
additional step III and step IV are on their way. CALE
Light includes step I with some minor limitations plus
parts of step II. Whenever a larger version of CALE is
bought, the price of your current version is deducted. CALE
consists of four parts: 1) Driver chassis part: it fits
impedance (MLSSA Data import), calculates inductor coils,
simulates 3D-dispersion plots (using finite element
methods) for axisymmetric drivers (ie. not oval drivers)
and Waterfall plots, based on the cone geometry of the
driver (over 100 geometries are provided with CALE, but you
can define your own). Included in step I are various
enclosure design capabilities, such as vented systems,
passive radiators and transmission lines. Also included are
complex filter networks, maintained with a graphic circuit
network editor which allows up to 5 groups with each up to
60 components in any order. Networks can be tested with any
given signal, and the power handling of each component can
be detected (power distribution in the network). You may
specify up to 10 separate (but coupled, if desired) boxes,
which means you can explore new box concepts - even several
drivers (not necessarily the same type) may share the same
box, and the mutual coupling will be included in the
analysis. 2) Step II contains the automatic optimization
routines, using a genetic algorithm (which includes some
influence by randomization so as not to get stuck in local
minima), where up to four target response curves may be
chosen for optimization (frequency curves, time- and/or
impulse response curves) under consinderation of the
radiation from the enlcosure walls. 3) Expansion A contains
the part for different cone geometries, which may be
explored in conjunction with a box, a horn or whatever is
desired. The cone can be assumed to have any desired
stiffness. The frequency response at any angle may be
calculated. A given dispersion characteristic for a given
driver may be desired (eg. a measured one) for higher
precision. 4) Step III and IV takes the room acoustics into
consideration. It uses Mirror combined with Ray-Tracing to
simulate a square or L-shaped room with regard to the
frequency spectrum, wavefield diagrams, intensity/position
diagrams, time relations, optimization of speaker position,
aftereffects and speech considerations etc. Each wall may
be given individual absorption coefficients. This part is
very processor and RAM intensive, even when compared to the
fastest computers of today (February 1997).

Price: US$320
Agent: Harmonic Design GmbH, Sonic Design AB, Munro Associates,
ME Technologies, Marton Music, Euterpe Audio
Demo disk: http://www.ljusdal.se/sd/caldem31.zip
Description: CALSOD 3.10 can model complete multiway (two-way, three-
way, four-way, etc) loudspeaker systems. Features include:
minimum-phase curve-fitting techniques enabling accurate
simulations of driver sound pressure and impedance
responses to be created, including phase response that is
important in crossover network design; simulation of sound
pressure and impedance response for vented, sealed,
passive-radiator, filter-assisted and bandpass
low-frequency alignments; the designer can specify the
positions of drivers on the baffle for accurate simulation
of effects on summed response caused by inter-driver time
delays to the listening position; optimization of
completely general user-defined passive and active
crossover networks with up to 60 components; standard
filter target functions for Linkwitz-Riley, Butterworth,
Bessel, constant voltage and user-defined designs;
curve-fitting optimizer for quickly creating sound pressure
models of driver response; curve-fitting optimizer for
creating impedance response models; curve-fit optimizer for
estimating driver Thiele-Small parameters (Qes, Qms, Qts,
Fs, Vas, Bl, Mms, Cms, etc) from experimental data using
added-mass or box loading techniques; driver Thiele-Small
parameters can also be estimated using a single measurement
of the driver impedance when mounted in a vented-box of
known volume and arbitrary tuning; driver impedance models
use frequency dependent voice-coil inductance and
resistance, parameters which can be automatically
determined by the impedance curve-fit optimizer and
Thiele-Small parameter estimator; automatic dcr
calculation for air-cored inductors; piston approximation
for driver models to simulate off-axis radiation
characteristics; specify orientation of the principal
radiation axis of each individual driver model used in the
loudspeaker system; import measurement files from MLSSA,
IMP, Audiosuite, CLIO, SYSid, System One, AIRR, PC Audio
Lab, AMS-PC, and LMS analyzers, with support for SPL
optimization using up to 5 observation points to account
for off-axis radiation characteristics; simulation of the
step in the sound pressure response caused by diffraction
of sound around the baffle; simulation of the effects of
floor reflections on the sound pressure response by setting
up a system of loudspeaker sources and images; simulation
of room gain effects on low-frequency response; modelling
of linear arrays. Plots include: impedance of each
individual loudspeaker driver; input impedance of the
crossover network and loudspeaker combination; voltage
transfer function of each filter when it is loaded by its
driver; filtered and unfiltered sound pressure response of
each loudspeaker driver included in the system; desired
target acoustic response function and target impedance
function; summed sound pressure response of a multiway
loudspeaker system, including the response at up to five
different observation points; magnitude and phase response
plots can be presented on a linear frequency scale to allow
the linear-phase behaviour of the loudspeaker system to be
easily assessed. The program comes with an extensive
printed user's manual with detailed tutorial examples.
Formulas are provided for determining initial crossover
component values for Butterworth, Linkwitz-Riley, and
Bessel filters.

Name: CALSOD 1.40
Computer: MS-DOS
Distributor: Audiosoft
Price: US$69
Agent: Old Colony Sound Lab, Sonic Design AB, Marton Music,
ME Technologies, Euterpe Audio, KEY Audio
Demo disk: http://www.ljusdal.se/sd/caldem31.zip
Description: CALSOD 1.40 is the low-cost edition of CALSOD 3.10, and
therefore has somewhat fewer features. It does not include
the active crossover design capability, nor the multiple
observation point and impedance optimizers, nor the ability
to directly import measurement files from audio test
systems. It still provides a complete system modelling
capability with the ability to predict the total summed
response of a multiway system (but the simultaneous
modelling of multiple off-axis response curves is not
available). The program is capable of modelling closed-box,
vented-box, passive-radiator and closed rear chamber
bandpass enclosures (both sound pressure and impedance,
including phase response). A passive crossover network
optimizer for multiway loudspeaker systems is also
included. The extensive 240-page user's manual is supplied
as a set of files on floppy disk, and it must be printed by
the user before use. The files are provided in Windows
Write 3.1 format, Word for Windows 2.0 format, and plain
formatted ASCII text files. The user's manual includes
detailed tutorial examples based on designing a two-way
system, and describes the techniques for modelling woofer
and tweeter response functions. Formulas are provided for
determining initial crossover component values for
Butterworth, Linkwitz-Riley, and Bessel filters, which are
used as an initial starting point prior to running the
crossover network optimizer.
