& Predict
& Predict

Room modes and modal distribution (Bonello criteria, histograms, mode tables)
RT60 targets (industry standards + custom targets) and required absorption calculations
Per-band RT60 planning: build a treatment schedule per octave band
3D room simulation: speaker/listener placement, early-reflection rays, bass modal response prediction
LiDAR room scanning (supported devices) with AR mode visualisation for rapid capture, on-site verification and visualisation of pressure zones

Acoustic Design Tools for Real-World Rooms

WM Toolbox replaces scattered spreadsheets, lookup tables, and desktop-only software with a single native app that runs the same physics used in professional studio construction. From first survey to final report, it covers the full acoustic design workflow.

This suite of tools were initially developed for internal use in evaluating project. They are now available in the app store for all to use.

Note: This app provides engineering tools and estimates; it is not a substitute for certified measurement instruments where compliance or regulation applies.
