Importing drawings and 3D models

DWG import

EASE 5-FE allows importing 3D models, or 2D parts of the room, in  DWG format. These can be complete rooms or just the basis for drawing a room in EASE.

  • Import DWG files from CAD tools such as AutoDesk AutoCAD software, Trimble SketchUp Pro or Rhinoceros 3D by Robert McNeel & Associates
  • Supports 3D Polylines, 3D Faces, and Polyface Meshes
  • Ensure model consistency using geometrical analysis tools of EASE 5-FE
  • Insert faces in holes and invert wrongly oriented faces to establish a model suitable for acoustic simulation
  • Assign acoustic materials to surfaces and add loudspeakers, audience areas as well as receivers to the model
DWG Import


Modeling based on drawings

For many projects, only section plans are available for 3D room modeling. In EASE 5-FE, floor plans, front and section views can be loaded as graphics files and used as a reference for drawing the room model.

  • Load various image file formats, such as JPG or PNG
  • Adjust orientation according to section plane
  • Scale drawings based on known dimensions
  • Position drawings in the 3D coordinate system as a reference for entering the room coordinates
  • Use projection functions and constraints to derive coordinates from the drawings interactively while entering surfaces, placing loudspeakers, and defining receivers
  • Hide or delete drawings after the room building is complete
Import Image Files.


Import and export of EASE 4 projects (.frd file format)

EASE 5-FE allows importing and exporting EASE 4 project files in FRD format. This makes it easier to get started in EASE 5-FE by loading existing projects created in EASE 4.4, as well as exchanging EASE data with 3rd parties who are still using EASE 4.4. Since the two software tools are conceptionally different, there are some limitations with respect to the compatibility between them.

Importing projects from EASE 4.4:

  • Faces, loudspeakers, audience areas and listener seats can be imported, objects are not yet supported
  • Coated and two-fold faces are converted automatically to EASE 5-FE faces
  • SPK speaker models are not supported and some loudspeaker filters settings are not maintained
  • Import log shows all corrections

Exporting projects to EASE 4.4:

  • Faces, loudspeakers, audience areas and listener seats can be exported, section drawings are ignored
  • Face in faces and holes are converted to EASE 4 faces
  • Filters of loudspeakers and processing blocks are combined and exported
  • Audience areas with more than four points are split
Import and Export FRD


Creating the 3D model 

To enter 3D models from the scratch or based on drawings, EASE 5-FE provides a light-weight CAD editor. The editor allows entering precise entering of coordinates by an intuitive drawing toolset. 

Faces can be created using a range of tools:

  • Insert points directly by mouse click or by snapping to existing points
  • Insert points by entering coordinates in absolute or relative mode
  • Use axis and plane constraints to infer 3D coordinates quickly
  • Snap to mid-points, surfaces and other elements
  • Infer coordinates from section drawings 
  • Derive intersections with room element


Use axis and plane constraints to infer 3D coordinates quickly.

    A large set of functions supports the creation and modification of the 3D room model. These functions are consistent with the drawing toolset provided for creating faces and are available for:

    • Inserting loudspeakers, audience areas, listener seats
    • Inserting faces in faces
    • Moving room elements to a new location
    • Extruding faces to create rooms or 3D bodies
    • Duplicating room elements one or multiple times 
    • Choosing an anchor point anywhere in the model for move, duplicate and extrude functions
    • Moving vertices and points
    Inserting faces in face.

      Additional functions supporting the room-building process include:

      • Multi-selection - selecting and modifying multiple items at once
      • Mirror items in X- and Y-direction
      • Create two-sides face configurations
      • Invert the orientation of faces
      • Insert audience areas above faces
      • Status display with context information about the selected element
      • Measurement of distances and delays
      • Previews during editing steps
      • Full undo / redo functionality
      Duplicated face preview.

        When it comes to finetuning the model, preparing it for the simulation and fixing potential errors, several tools and views help to find potential geometrical problems in the model or acoustically wrong oriented faces.

        • Apply view slices to hide parts of the model
        • Use the x-ray and wireframe views to better understand the 3D structure of the model
        • Switch to parallel perspective to verify model consistency using standard view directions
        • Activate geometrical analysis tools that highlights holes and stacked faces in the model
        • Refer to the calculation results for room volume and surface areas
        Missing faces indicated by the outlines highlighted in red and stacked faces highlighted in yellow.

                    Direct field mapping (JR, Std, Pro)

                    The direct field mapping functions of EASE 5-FE offer a set of different result outputs that are used to optimize the coverage of the sound system.

                    Example of direct SPL mapping.

                    The direct field mapping results include the following mappings:

                    • Direct SPL
                    • Arrival times
                    • Loudspeaker coverage overlap
                    • Initial Time Delay (ITD) Gap
                    Mapping functions (JR, Std, Pro)

                    Generally speaking, mappings can be calculated on faces, audience areas and listener seats. For all mappings the following evaluation functions are available:

                      Acoustic Parameters window.

                      Mapping of room acoustic results

                      The Standard Mapping function allows a large number of simulations to be performed based on the diffuse field assumptions of statistical acoustics. Standard Mapping makes use of Eyring statistical formula to generate RT figures that will be used to calculate acoustical parameters, such as STI (Speech Transmission Index) and Total SPL. Measured RT data can also be used for this type of mapping.

                      STI mapping example.

                      In addition to the direct field results the following room acoustic results are provided using Standard Mapping functions:

                      • Total SPL – Sum of direct + reverberant sound field
                      • Speech intelligibility measures: STI according to IEC 60268-16:2020, RaSTI, ALCons
                      • D/R Ratio (Direct/Reverberant ratio)
                      • Critical Distance
                      • Clarity and Definition Measures: C7, C50, C80, C-Split
                      • Sound Pressure Levels: L7, L50, L80, L-Split

                      The same evaluation functions as for the direct field mapping are available for these mappings, as well.

                      Ray-tracing and reflection analysis (Std, Pro)

                      Standard Mapping with Reflections, Local Decay Time

                      Standard mapping results based on statistical acoustics can be extended by including early, specular reflections using simple ray-tracing functions. Using this combination, the same room acoustic quantities are calculated in a mapping format. 

                      • Total SPL – Sum of direct + reverberant sound field
                      • Speech intelligibility measures: STI according to IEC 60268-16:2020, RaSTI, ALCons
                      • D/R Ratio (Direct/Reverberant ratio)
                      • Critical Distance Clarity and Definition Measures: C7, C50, C80, C-Split
                      • Sound Pressure Levels: L7, L50, L80, L-Split
                      • Privacy Index, Articulation Index
                      Standard mapping with reflections menu option.

                      Additionally, the Local Decay Time mapping allow analyzing local reverberation times with respect to selected positions in the room.

                      The same evaluation functions as for the direct field mapping are available for these mappings, as well.


                      Reflection patterns

                      Using the Ray Tracing module, reflection patterns can be calculated, analyzed, and visualized in order to find, e.g., audible reflections, focusing effects, and flutter echoes. They can also be used to aim loudspeakers and reflectors. The following functions are available for this purpose:

                      • Control ray tracing process by cut-off criteria (reflection order, time) as well as number of rays
                      • Select loudspeakers of interest as ray sources
                      • Optionally, select faces that should be considered for reflections
                      • View results in the 3D model as rays or as sound particles, at fixed points for time or animated
                      • Color coding for different conditions and parameters
                      • Save and recall result files
                      Viewing reflections over a selected face.

                      Reflection analysis

                      The Ray Tracing module also calculates response functions for user-defined locations in the room. These so-called reflectograms contain precise information about each reflection, such as its arrival time, level, frequency response, and direction given a listener seat or measurement position.

                      In combination with the Probe module and the 3D wireframe view of the Ray Tracing module, the reflectograms can be analyzed interactively in many different ways:

                      • Step through all reflections found and highlight each one in the 3D view and in the Probe reflectogram
                      • Select individual reflections in the Probe reflectogram view to identify and investigate the paths of audible echoes
                      • Use the Movie function to view an animation of sound particles moving through the room in 3D
                      • Use the 3D hedgehog display to obtain an impression which directions important reflections come from
                      • Look at reflection points and level losses along the propagation path of the ray
                      Selecting individual reflections in the Probe reflectogram view.

                      Measurement Probe

                      The Probe module of EASE 5-FE is used to view and analyze response files and reflectograms calculated primarily using ray-tracing methods. It works similar to a measurement suite and offers many different views and evaluation methods.

                      A number of displays are available, including:

                      • Reflectogram
                      • Impulse Response (IR) and Energy Time Curve (ETC)
                      • Waterfall
                      • Frequency Response (for sound sources and even for each reflection)
                      • Sound Pressure Levels (Direct SPL, L7, L50, L80, Total SPL, L-Split)
                      • 3D Hedgehog (Direction and Relative Level – Horizontal, Vertical or 3D)
                      • Phase Angles
                      • Reverberation Times including Schroeder RT, Eyring RT and tolerance ranges
                      • Modulation Transfer Function (MTF), Speech Transmission Index (STI) according to IEC 60268-16:2020
                      • Clarity and Definition Measures (C7, C50, C80)

                      If the response is not the result of a full-length ray tracing simulation using AURA, it can be extended by a predicted tail to obtain an approximately complete impulse response.

                      Further editing and analysis functions include the ability of activating or deactivating parts of the response:

                      • Loudspeakers
                      • Reflection orders
                      • Single reflections

                      The response file can be transferred to the EARS module for auralization (Pro feature level only).

                      Full-length mapping and response analysis (Pro)

                      Full-length analysis with scattering (AURA module)

                      The AURA module provides advanced ray-tracing functions. They make use of a 64-bit engine and multi-threading in order to calculate accurate, full-length echograms and impulse responses including scattering effects and without tail estimates. This allows deriving all important acoustic quantities according to ISO 3382 and IEC 60268-16 with high accuracy.

                      Important calculation parameters for calculating full-length mappings and room responses can be adjusted by the user, including:

                      • Time length (cut-off time)
                      • Number of particles
                      • Scattering curve including the so-called S-curve
                      • Number of threads
                      • Loudspeakers in use
                      STI simulation in a stadium with AURA Mapping.

                      Full-length mapping

                      The AURA Mapping function provides the following results in a mapping format:

                      • Direct SPL
                      • Arrival Time
                      • Total SPL
                      • Clarity and Definition Measures (D, C50, C80)
                      • Center Time
                      • Reverberation Times EDT, T10, T20, T30
                      • Lateral Fraction LF and LFC
                      • Sound Strength G
                      • STI (according to IEC 60268-16:2020) and ALCons
                      • Echo Criteria for Music and Speech
                      Theatre - T30 simulation by AURA.

                      The same evaluation functions as for the direct field mapping are available for these mappings, as well.

                      For each receiver position the following data is additionally available:

                      • Echograms for all frequencies
                      • Histogram
                      • Integration curves for echo criteria
                      • Forward energy sum, Schroeder backward integral and intensity integral

                      Full-length response analysis

                      The AURA Response function calculates full-length response files in the following formats:

                      • Response (RSP) files for detailed analysis in Probe module
                      • Binaural (BIR) files for auralization in EARS module
                      • B-Format (WAV) files for auralization in Ambisonics setups

                      The same Probe evaluation functions as for specular ray-tracing results are available for AURA Response results.

                      Full-length auralization (Pro)

                      Auralization is the process of simulating and making audible the effects of playing a known reference sound, such as program material, through a defined loudspeaker system in a particular space. It allows listening to the room before it is even built and therefore allows adding subjective impressions to the design process.

                      The EARS module of EASE 5-FE provides the means to perform auralizations. These can be based on the direct sound response only or on the results of specular ray-tracing runs with or without a predicted tail. However, the most accurate listening results are achieved using the output of AURA Response calculations.

                      Many different effects can be made audible using the EARS auralization module:

                      • Listener vs loudspeaker location and orientation
                      • Level differences and directions
                      • Localization of sources
                      • Colorations
                      • Flutter echoes
                      • Slap-back reflections
                      EARS Convolver Window Open.

                      Additionally, the following main features are provided by the EARS module:

                      • Creation of BIR filter files using selected HRTFs
                      • Display of BIR files as binaural impulse response or frequency response
                      • Auralization using BIR files and dry signal input files (WAV) or from a live source (real-time convolution)
                      • Stereo convolution and mixing
                      • Built-in signal generator
                      • Batch processing for preparing multiple auralizations
                      Continuous feature development and outlook

                      AFMG will provide updates continuously within the time limit of the purchased license, free of charge.

                      With EASE 5-FE, we are set up for an agile development process. It will balance the development of new strategic features with the improvement of existing functionality and the implementation of features in response to user feedback.

                      Our approach is based on rigorous quality control, sustainable feature development, and flexibility to react to new market developments. 

                      For us it is the ultimate goal to establish the Enhanced Acoustic Simulator for Engineers on a new platform so that we are able to provide sound system designers as well as room acousticians with a solution that allows them to work most efficiently, create great designs and eventually achieve the best sound and acoustics possible.

                      EASE 5-FE is a growing tool that implements well-known features from EASE 4.4 as well as new functionality. We are continuously making improvements, at the moment primarily in the following areas:

                      • Expand import and drawing facilities
                      • Add more grouping functions
                      • Extend loudspeaker configuration options

                      For more information about our vision and motivation please see our EASE Development website or send us an email!

                      Loudspeaker Database

                      Several manufacturers have provided their licensed EASE data to AFMG for distribution. The loudspeaker speaker data can be downloaded as a whole package or sorted by manufacturer from the list below.

                      How to install:

                      • From within EASE 5-FE (Loudspeaker Ribbon -> Import GLL) import ZIP, GLL or DLL files.
                      • The files will be stored in an internal database and will be available for use in any EASE 5-FE project

                      Please note:

                      • Some manufacturers distribute the loudspeaker data only through their website or upon request. If you are missing a particular brand in the software, please contact the respective company directly. For an overview of all the supported brands for all AFMG products, please refer to our Supported Brands list.
                      • AFMG is not responsible for this data. If you have questions regarding accuracy, completeness or up-to-dateness please consult the manufacturer.
                      • GLLs for loudspeakers and line arrays available for EASE 4 can be used also for EASE 5-FE. The same applies to latest-generation DLLs. Speaker models based on cluster-type GLLs are not yet supported in EASE 5-FE. Speaker models based on SPK files are not supported in EASE 5-FE.
