Getting started

Everything in RoomSense starts with three numbers: the room's internal length, width and height. From those it derives the modes, the proportions verdict, the RT60 estimate and, on the Results tab, the synthesis. The first time you open it, an example club (18 × 12 × 6.5 m, 300 people) is filled in — replace it with your venue.

Quick start

1. Open RoomSense from the dashboard. You land on the Room Modes tab.
2. In Room Dimensions, enter Length, Width and Height in metres (internal clear dimensions). A German decimal comma works: 3,5 is 3.5.
3. Read the modal chart: every axial, tangential and oblique mode up to about twice the Schroeder frequency. The L : W : H badge says whether the proportions lie in the EBU Tech 3276 region and whether two dimensions stack modes on the same frequencies.
4. Scroll to the RT60 Estimator, pick a material for each surface, add the audience and read the reverberation time against the DIN 18041 target for this volume. See Estimate RT60 and size the treatment.
5. Type a name in the Venue name field at the top and press Save. The room is now a venue profile on all your devices; the top bar shows Saved or ● Unsaved changes.

The tabs

Delay Alignment (EQ & Delay) gives the delay for a speaker nearer the listener than the main — a delay tower, a front fill: enter how much further the main's sound travels to that point. The speed of sound follows the air card's temperature. The result comes in milliseconds and in samples at 48 and 96 kHz. The badge rates what the listener hears after alignment — the Haas offset: Time-aligned at 0, Main stays the source up to 30 ms, Echo risk beyond. Delay → distance answers the reverse question.

Sub Polarity Check takes distance to sub minus distance to tops and tells you which box to delay and by how much, with the phase at the crossover.

Every tab ends with a Print A5 button; the sheet carries the venue, the room and the date.

The top bar

• Venue name, — Select venue —, Save and Delete manage venue profiles — dimensions, materials, targets, the rule and the calibration.
• Import and Export move profiles as a JSON file between devices or colleagues.
• ◐ toggles dim mode for front-of-house in a dark room. The choice follows your account.

Venue profiles sync to your account record by record, with a local copy on the device — a profile saved offline never deletes one another device made. A reload brings back the numbers you were working on and the open tab.

Core concepts

• Room modes are the standing waves a rectangular room supports; axial modes are the strongest. Below the Schroeder frequency the room behaves modally, above it statistically.
• RT60 is how long sound takes to fall 60 dB after the source stops. What is "right" depends on the volume — DIN 18041 gives a target per room size. RoomSense estimates it.
• "?" tips. Every technical term has a ? button with a plain explanation, in your language; Esc closes it.

Next

• Estimate RT60 and size the treatment — materials, audience mode and panel counts.
• Exposure, hearing protection and the crew's day — how long the crew can stand at that level.
• The rule where you play, the correction value and the protocol — the rule where you play, and the protocol.
