PRIVACY & LIMITATIONS

Room dimensions stay local. No microphone is monitored.

Room dimensions, sound speed, frequency ceiling, RT60, map height, and crowding threshold are calculated only on the current page. RoomMode does not request microphone, recording, floor-plan, or location access, and it never plays test signals.

Rigid rectangular model, not an acoustic measurement

The tool enumerates ideal modes below the chosen ceiling as c/2×√((nx/L)²+(ny/W)²+(nz/H)²), classifies them by non-zero axes, flags crowding from adjacent frequency gaps, and draws a 24×16 relative-pressure map at one height. The Schroeder transition is only a statistical estimate from volume and RT60. It does not model wall loss, openings, sloped walls, furniture, speaker/listener positions, treatment, phase, frequency response, decay time, or measured transfer functions.

Room dimensions can describe a private space

Refreshing or closing discards current inputs. CSV contains mode indices, types, frequencies, pitch names, and adjacent gaps; the report studio and optional local checkpoints read the visible summary. The page does not collect addresses or floor plans, but exact dimensions and acoustic targets may still describe a home or unreleased venue, so review them before sharing.

Advertising and local preferences

This page uses Google AdSense Auto Ads. Google may use cookies or similar technologies under its policies. .miluland.com domain cookies sync language, theme, high contrast, a six-item recent-tools list, and up to 16 favorite tool IDs across MiluLand sites. These values never contain inputs, files, or results; the current site also keeps a local compatibility copy.

Local report studio

The report studio reads only the workbench’s currently visible result summary for local preview, Markdown copy, JSON download, printing, and a SHA-256 fingerprint. It never reads input controls or original files and is not persisted unless you choose to download it.

Optional local checkpoints

Only when you explicitly choose Save does the tool write the visible result summary, time, and optional short label to this site’s browser storage, up to five entries. Imported files and input-control contents are never stored; you can export, restore same-tool checkpoints, or clear them at any time. Imports are limited to 128KB and validate the tool, timestamp, summary, and label of up to 80 characters.
