Welcome to the Integral Acoustics website, home of the LARA
sound system design software.
Integral Acoustics is the developer
of the LARA louspeaker covergae
and placement analysis software.
LARA can be used to predict the
direct field coverage of one or
more loudspeakers over a defined
listening area. In the basic
package the listening area is
defined by selecting from a library
of room shapes and entering the
Loudspeaker coverage data can
be read from EASE 2 or 3 format
data files. The cabinet geometry is
added to the imported data and all
data is stored in a native cabinet
Major features include:
1. Definition of rooms using a
library of pre-defined shapes. You
just supply the key dimensions.
2. Definition of rooms with arbitrary
geometry (with optional full
3. Mouse driven display pan,
zoom and rotate.
4. Calculation at third octave
5. Choice of power summation or
complex addition to calculate
coverage and response
6. Display of contours showing
SPL or geometric data (e.g.
distance from loudspeaker) on
individual surfaces or groups of
7. Line of sight acoustic
shadowing calculations show
regions that have no line of sight
8. Choice of results display
modes, trading off speed of
calculation for resolution. Spot
mode gives virtually instantaneous
9. Display of signal arrival time
and levels for individual
loudspeakers (Direct ETC) at a
10. Directly shows the affect of
adding delays to loudspeakers.
