LARA Features


Download

 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 key dimensions.  



  Louspeaker coverage data can be read from EASE 2, EASE 3 and CLF  format data files. The cabinet geometry is added to the imported data and  all data is stored in a native cabinet library. Many CLF files contain the cabinet geometry already. 

You can download a demo version of LARA from our Dropbox site. Just click the link then click the download button when it appears. Download

Major Features Include:

  •  Definition of rooms using a library of pre-defined shapes. You just  supply the key dimensions.
  •  Definition of rooms with arbitrary geometry. 
  •  Mouse driven display pan, zoom and rotate. 
  •  Calculation at third octave frequencies.
  •  Choice of power summation or complex addition to calculate coverage  and response
  • Display of contours showing SPL or geometric data (e.g. distance from  loudspeaker) on individual surfaces or groups of surfaces. 


  • Line of sight acoustic shadowing calculations show regions that have  no line of sight to loudspeakers.  
  • Choice of results display modes, trading off speed of calculation for  resolution. Spot mode gives virtually instantaneous coverage display. Have you opened a new location, redesigned your shop, or added a new product or service? Don't keep it to yourself, let folks know. 
  • Display of signal arrival time and levels for individual loudspeakers  (Direct ETC) at a discrete point. 

  • Display of computed frequency response at discrete points. Display  has separate controls for display and calculation resolution with  smoothing.
  • Loudspeakers can be configured in clusters which can then be added  to the room and oriented as a single unit. 
  •   Loudspeakers arranged in regular patterns can be quickly configured  as clusters using array definitions. 
  •  Probe reports computed values at a location simply by clicking  on it. 
  •   An Ear Height correction can be entered.

  • Generates report showing average power requirements, peak  power requirements and mass for each loudspeaker and cluster and  for the whole system. Loudspeaker headroom is also reported.
  • Export of room geometry to CATT-Acoustic
  • The room can be viewed in 3-D wireframe and a probe can be used  to determine the SPL, distance from loudspeaker and loudspeaker  angles for a selected point. 
  • Loudspeakers can be assembled into clusters and then placed and  oriented together.

  • SPL over surfaces, calculated by power or complex summation.
  • Signal arrival time and level from every loudspeaker.
  • Direct frequency response at any audience location.
  • Loudspeaker headroom, input power required and total weight.
  • Geometric data such a distance and angle from selected  loudspeaker.
  • Room volume. 

LARA is priced at $350 Cdn.
