White Mark Acoustic Toolbox is a professional room-acoustics, measurement and reporting platform for acousticians, studio designers, audio engineers and critical-listening specialists. Plan, model, measure, document and share acoustic projects from one app, whether you are checking an existing room, developing a studio concept, reviewing treatment options or preparing client-facing reports. ROOM DESIGN & PREDICTION • Room mode analysis with modal tables, histograms and Bonello distribution checks • RT60 target planning using industry-standard and custom targets • Per-band absorption planning for octave-band treatment schedules • Room optimiser for comparing dimensions and ranking modal performance • 3D room simulation for speaker/listener placement, early reflections and bass response prediction • LiDAR room scanning and AR visualisation on supported devices for rapid room capture and on-site checks MEASUREMENT & VERIFICATION Use the built-in microphone or a class-compliant audio interface / USB measurement microphone where supported. • SPL Meter with A, C and Z weighting, Fast, Slow, Impulse and Leq modes • RTA with 1/3-octave and 1/1-octave spectrum analysis • Spectrogram with 2D and 3D Metal-accelerated frequency-over-time views • Oscilloscope with real-time waveform display, triggered capture and fundamental frequency detection • THD+N meter for sine-wave distortion analysis • RT60 capture from broadband noise decay • NC/NR analysis with full curve family charting and RC Mark II descriptors • Signal generator with pink noise, white noise, log sweep and polarity test tones • Dosimeter for occupational noise exposure logging against OSHA and NIOSH references • Experimental vibration analysis using the device accelerometer APPLE WATCH COMPANION • Start and stop captures, monitor live SPL and review Noise Criteria telemetry from your wrist while moving around the room. TREATMENT & ABSORBER TOOLS • Porous absorber design using the Miki model • Panel, membrane and Helmholtz absorber tools in Pro • Multi-layer absorber stacks in Pro • Assign calculated absorption to room surfaces • Compare saved absorber designs and export specifications PROJECT WORKFLOW • Create projects, save measurements, add editable notes and organise work by phase. The Project Manager lets you review local projects, load the current project across tools, rename, duplicate, delete and manage project archive workflows. • Project Archives use the .wmarchive format to package project metadata, saved measurements, notes and project-scoped tool state into a self-contained file. Export a project for backup or collaboration. EXPORTS & REPORTING • Generate PDF reports and CSV exports from key tools, including project metadata, charts, measurement summaries and saved notes. TIERS Free: core room analysis, per-band planning and material viewing. Pro: unlimited projects, full simulation suite, absorber tools, optimiser and PDF/CSV exports. Commercial: Pro features plus commercial-use rights and white-label report branding for client deliverables. White Mark is a specialist acoustic design consultancy for recording studios, immersive audio rooms, post-production, broadcast and critical listening environments worldwide. The tools in this app were originally developed to support professional acoustic design workflows and are now available for broader use. Important: White Mark Acoustic Toolbox provides engineering tools, estimates and device-based measurements. It is not a substitute for calibrated, certified measurement instruments where regulatory, compliance, safety or diagnostic decisions are required. Vibration readings are experimental, accelerometer-based and should be verified with appropriate calibrated equipment before use in any formal assessment. ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | White Mark Commercial Monthly | $14.99 | per month | | White Mark Pro Monthly | $2.99 | per month | | White Mark Pro Annual | $24.99 | per year | | White Mark Commercial Annual | $149.99 | per year | ## Version history (last 4 releases) ### 1.07.3 — 2026-05-14 Version 1.07.3 adds a much stronger project workflow, portable project archives and several measurement-history improvements. NEW PROJECT MANAGER A new Project Manager is available from the More tab. You can now review local projects, load a project as the current working project across tabs, rename, duplicate, delete, export archives and import archives from a single place. PROJECT ARCHIVES Projects can now be exported as self-contained .wmarchive bundles containing project metadata, saved measurements, notes and available project-scoped tool state. Archives can be opened from Files, Mail, Messages, Google Drive and other document providers to launch the app and start the import workflow. Safer import/export handling has also been added. Archives are checked before sharing, and imports validate structure, manifest data, hashes, project contents and duplicate names. Imported archives default to a renamed copy so existing local projects are not overwritten. MEASUREMENT NOTES & GRAPH WINDOWS Saved measurement notes can now be edited from the session detail screen without changing the original measurement date, captured payload, measurement type, phase or calibration metadata. Live and saved Spectrogram views now support selectable 15s, 30s, 60s, 2m and 5m time windows. SPL graphs now use the same selectable live and saved graph-window controls. FIXES & REFINEMENTS • Dashboard project renaming no longer creates duplicate rows. • Current-project indicators now track project ID rather than project name. • Deleting a duplicate-named project now removes only the selected project. • 3D Spectrogram PDF reports use a taller viewport to avoid clipping. • Edited notes refresh immediately in detail views, history lists and PDF/CSV export data. • Added an in-module notice explaining that vibration readings are experimental and accelerometer-based. ### 1.06 — 2026-03-26 Version 1.06 — Acoustic Measurement Expansion SPECTROGRAM 2D and 3D Metal-accelerated visualisation of the frequency spectrum over time. Observe decay characteristics, transient resonances, and room behaviour in real time. Rotate and explore the 3D mesh view on supported devices. OSCILLOSCOPE Real-time raw audio waveform display with triggered capture mode. Automatic fundamental frequency detection identifies the dominant pitch in your signal. THD+N METER Total Harmonic Distortion plus Noise measurement module. Analyse distortion ratios from a pure sine wave signal — ideal for verifying monitor and signal chain performance. VIBRATION ANALYSIS Measure structural resonances from 0.5–50 Hz using your device's built-in accelerometer. The app identifies resonant peaks and annotates them by likely source (HVAC, building floor, motor). Reports whole-body vibration comfort ratings per ISO 2631-1. Full spectrum data now exports cleanly to CSV and renders as a bar chart in PDF measurement reports. ENHANCED NOISE CRITERIA The NC/NR view now plots the full NC curve family (NC-15 through NC-70) as background reference curves with your measured spectrum overlaid. Includes RC Mark II quality descriptors (Neutral, Rumble, Hiss) and per-band dB axis labels. IMPROVEMENTS • iPad multi-view mode now correctly restricts Spectrogram, Scope, and THD selection when in split-pane layout. • Redesigned RT60 idle-state layout with a clean card-based design and capsule status indicator. • Signal Generator routes correctly through the main speaker on all iOS devices. • Updated in-app Help Guide with full documentation for all new measurement tools. ### 1.05 — 2026-03-18 Version 1.05 — Major UI and calculation upgrades: FITZROY RT60 & PER-SURFACE ABSORPTION Fitzroy RT60 calculations for rooms with non-uniform treatment. Assign targeted absorption materials to all six surfaces (front, back, left, right, floor, ceiling) across all design tools. ENHANCED PDF REPORTS Exports now include rendered 3D modal visualisations with improved layout and detail. UI & ACCESSIBILITY New Liquid Glass interface for AR tools. 120Hz ProMotion support. Full adaptive layouts for XXXL Dynamic Type and improved chart contrast throughout. MacOS IMPROVEMENTS Smoother window management, native print support, and standardised toolbars across the Catalyst experience. Plus engine optimisations, calculation refinements, and bug fixes throughout. ### 1.04 — 2026-03-09 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
