FAQ

Is RoomSense free?

Yes. The full suite is free with a Squaresmile account.

Where does my data go?

The calculations run in your browser. Live audio from the microphone never leaves the device. What you save — venue profiles and show protocols — syncs to your Squaresmile account, with a local copy on the device. There is no third-party analytics.

Does it replace REW, Smaart or a sound level meter?

No. RoomSense predicts and references, and its level monitor is indicative. Use it before you are standing in the room, then measure with a proper system.

Is the RT60 measured?

No. It is an Eyring estimate with air absorption from your dimensions, materials and audience. See Estimate RT60 and size the treatment.

Which exposure rules does it use?

For a level: NIOSH (85 dB(A), 3 dB exchange) and OSHA (90 dB(A), 5 dB, never above 115). For the crew's day: the EU values 80 / 85 / 87 dB(A) LEX,8h. For the audience: DIN 15905-5, V-NISSG, WHO, the Dutch covenant, the French décret, VLAREM and HSE guidance. See Exposure, hearing protection and the crew's day and The rule where you play, the correction value and the protocol.

Can the level monitor replace a class meter?

No. It is a browser with a phone or laptop microphone — indicative, after you calibrate it against a real meter. For a record a regulation or permit asks for, use a class 2 meter and import its log into the show protocol.

Which loudness targets are built in?

Spotify, YouTube, Amazon HD, Tidal and generic streaming at −14 LUFS, Apple Music at −16, podcast −19 to −16, and EBU R128 at −23 (±0.5 LU). The table lists each platform's true-peak ceiling for reference; RoomSense does not measure true peak — LoudSense does, for files.

Can the live LUFS meter measure the PA?

It meters whatever your input hears — momentary, short-term and integrated, BS.1770 with overlapping blocks and R128 gating, every channel summed (two identical channels count as one). The number depends on your input gain.

Which standards does it reference?

Eyring with ISO 9613-1 air absorption, DIN 18041, EBU Tech 3276, the Schroeder frequency, ISO 226, ISO 7029:2017, IEC 61672 A / B / C / Z, ITU-R BS.1770 / EBU R128, NIOSH / OSHA, EU Directive 2003/10/EC, and the audience rules above.

Can I share a venue with the crew?

Yes. Profiles sync to your account; Export writes them to a JSON file anyone running RoomSense drops in with Import.

Can I print it?

Every tab has a Print A5 button; the audience notice and the show protocol print on A4.

Does it work on a phone?

Yes — the tabs stay pinned, tables scroll sideways, and every control is touch-sized. The charts are roomier on a tablet or laptop.

Which languages does the interface speak?

The platform's 11 languages — labels, results, messages and the ? tips follow the language picker.
