Treble web application - 21/05/2026​

3D viewport visualization toolbar:​

  • Added a new viewport toolbar with several visualization modes, available in both the editor and results views:
    • Particle animation — visualize how sound reflections propagate through the model in real time.
    • Reflection density — highlight surfaces based on how many reflections reach them, filterable by reflection order and source.
    • Absorption coloring — color surfaces by their absorption coefficients, with a legend and controls.

Wavefield animation for surface receivers:​

  • New wavefield analysis mode that animates the time-varying sound pressure field from wave-based (DG) simulations on surface receiver grids. The surface mesh is displaced in 3D based on pressure amplitude, giving a physical visualization of how sound propagates and decays over the receiver surface. Includes a timeline scrubber and adjustable playback speed.

Surface receiver comparison (delta view):​

  • Compare surface receiver results across two simulations side by side in a single difference heatmap, making it easy to see how changes to the model or simulation settings affect the acoustical parameters.

Surface receiver results view:​

  • Redesigned the surface receiver results UI/UX to accommodate the new visualization options.

Reference curves in Reflection tracking:​

  • Added a reference curves chart in the Reflection tracking tab with environment-specific presets for Speech and Music, making it easier to evaluate reflection patterns against established criteria.

Grid receivers:​

  • Increased the maximum number of grid receiver points to 2,500, enabling denser and larger receiver grids.

Resizable results panels:​

  • Added draggable horizontal split panes in the Results view, allowing you to adjust the layout between the results panel and the 3D viewport.

Rhino integration:​

  • Added a new Treble plugin for Rhino, allowing you to prepare and upload acoustic models directly from Rhino. The plugin supports geometry layer setup, cloud-based geometry validation with detailed feedback, uploading models to Treble, and fetching geometry back into Rhino. Install via Rhino's Package Manager.

Performance:​

  • Significantly improved source summing performance, resulting in faster processing and support for larger summing jobs.
  • Improved model loading performance with asynchronous loading and precomputed geometry metadata.

Treble web application - 06/02/2025 - Our biggest update ever​

Features

  • IFC import

    • The ability to upload .ifc files directly into Treble with automatic space extraction and geometry simplification. Read more here.

  • Source summing

    • Sum multiple sources within the results view to see the combined IR and its derived acoustical parameters. Read more here.

  • Forced modal analysis

    • Visually analyze the spatial distribution of the frequency response for the selected individual or summed source on a heatmap. Read more here.

  • Multi GPU support

    • Run bigger wave based jobs than possible before or run smaller jobs faster with the new automatic multi GPU feature. Read more here.

  • STI update

    • Estimate the STI resulting from one or more combined sources with user defined source characteristics. With this update you can now analyze the STI of PA (public announcement) systems. Read more here.

  • Source proximity update

    • Assign sources closer to surfaces than possible before, both in the geometrical solver where all limits have been lifted and the wave based solver where the limit now gets lower with increased transition frequency. The new limits for hybrid and wave based simulations are as follows:
      • Octave band centered on 125 Hz - 50 cm
      • Octave band centered on 250 Hz - 40 cm
      • Octave band centered on 500 Hz - 20 cm
      • Octave band centered on 1000 Hz - 10 cm
      • Octave band centered on 2000 Hz - 5cm

  • Save result setup

    • The ability to save a setup within the results view for quick future access and collaborative sharing.

  • In app tutorials

    • A tutorial section has been added to the homescreen with a tutorial on the new source summing feature.
Updates
  • Homescreen overhaul
    • The homescreen has been overhauled with a new look. The update includes a new side panel, a filterable task window and a section for recently worked on spaces and projects.
  • Project hierarchy
    • The project hierarchy has been revamped along with associated UI/UX changes. Read more here.
  • Upgraded IR generation algorithm for ray-radiosity
    • The pulses in the IR's is now based on a "Poisson sequence" rather than being converted directly from the raytracing binned energy.
    • Each pulse in the sequence is converted into a time signal by synthesis in the frequency domain, this enables the timing and phase of each pulse to be set with a floating point number, resulting in better variation in the resulting IR.
    • Each pulse is distributed energy from binned energy from the ray-radiosity raytracing, Using the binned energy as an envelope rather than the actual response.
  • Updated parameter generation
    • All acoustical parameters are now calculated directly from the impulse response, both for the wave based solver (as was done before) and the geometrical solver. This allows for more accurate parameter generation in the geometrical solver, as the pressure based image source method accounts for the angle of incidence which is now factored into parameter results. Note that this means that when rerunning old simulations results might change slightly. Read more here.
  • New setup sheet in the downloadable results
    • When downloading the ‘Parameter values’ .xlsx sheet for a given simulation a new ‘Setup’ sheet has been added. The sheet contains information on both the solver setup for the simulation (transition frequency, number of rays etc.), the materials assigned to each layer and their respective absorption coefficients and absorption area per octave band.
  • New spectrum for STI calculations
    • There are now two options when analyzing STI results. The new 'Source SPL level', which returns the STI based on the gain and directivity of the chosen source and the 'Speech spectrum - ISO 3382-3'. The latter option returns the same STI as before the update, with the caveat that the speech spectrum used as basis for the calculations has been updated to account for it only being available for omnidirectional sources. Read more here.
