Floorplan Sound Simulation
See the sound before you install it.
A browser-based acoustic design tool for AV integrators. Upload a floor plan, trace the rooms, place speakers, and it predicts what every zone will actually sound like — SPL coverage across Low, Mid and High bands, room modes, first reflections and stereo imaging, with absorption set wall by wall and acoustic panels placed into the room, or the full Dolby reference geometry for a home cinema, checked speaker by speaker. Then it produces the paperwork: a report that adapts to whether the room is for music or cinema, a full bill of quantities, an Excel quotation that round-trips your prices, and a client-ready PDF. The design tool is free, with no account required.

Eight Guided Steps, No Manual
Floor plan to coverage map, no manual.
- Upload, trace, scale, place, view, detect furniture, set the seat, set the rack
- Every step autosaves in the browser
- Nothing is lost on a refresh or a closed tab
A project is structured Floors → Zones — a whole villa, apartment or commercial fit-out in one file. Every floor gets its own plan image and scale; every zone gets its own SPL map, room modes, reflection analysis and speaker schedule. The bill of quantities and the PDF report roll every zone on every floor into one set of project-wide totals — not a single-room tool you have to run over and over.
Floor plan to priced proposal.
Eight steps, one tool.
Upload floor plan
PNG, JPG or WEBP — drag onto the window or browse. One plan per floor.
Trace room outline
Click the corners to define each zone. Vertices are editable afterwards.
Set scale
Click two points of a known distance, enter it in metres or feet. Everything downstream is real-world accurate.
Place speakers
Drag from the real XSCACE catalogue. Speakers snap to walls, rotate freely, and can be set as ceiling-mounted.
View coverage
The SPL map — a calibrated heat map of what the system will actually sound like.
Detect furniture
AI reads the plan and finds sofas, beds, wardrobes, rugs — they block and absorb sound in the simulation.
Set MLP
The main listening position, which drives reflection analysis.
Set rack
The head-end location, from which all cable runs are estimated.
Design it, then prove it.
A prediction is only as good as its assumptions. Measure the room on site with the Calibration Toolkit in the XSCACE Studio — a real RT60 and ambient noise (NC) reading — and enter it into the planner. The measured RT60 is mathematically inverted into the room’s true average absorption, which then re-drives the whole simulation.

Frequently asked questions16 answers
Is the Floorplan Sound Simulation free?
The design tool is free with no account required — simulation, room analysis, bill of quantities and Excel export all work signed out and autosave in your browser. XSCACE Pro adds unlimited branded PDF reports, the AI tools, saved price lists, cloud projects and third-party equipment.
How much does XSCACE Pro cost?
US$49.99 per user per month, billed in your local currency, after a 14-day free trial. Paying annually gives two months free — $499 a year. Active XSCACE dealers get Pro at no cost.
What do I get on the free tier?
Multi-floor simulation, room modes, the 3D view, the full bill of quantities with Excel export, signal-flow diagrams, the commissioning checklist, and rack layout with cable estimation. Free includes 3 client PDF reports a month and 25 AI requests (8 if you are signed out).
Do I need an account?
Not to design. Simulation, room analysis, BOQ and Excel export all run signed out and autosave in the browser. An account is needed for cloud projects, saved price lists, your branding on reports, and the AI features.
What happens when the Pro trial ends?
Nothing is deleted. Your projects and price lists stay, the Pro features pause, and the free tool keeps working exactly as before.
Can I use other manufacturers’ speakers?
Yes, with Pro. Add any product manually, or upload its spec sheet and let the AI extract the sensitivity, power and dispersion the simulation needs. Added products join a shared community catalogue.
Can I simulate a whole house, not just one room?
Yes. Projects are structured Floors → Zones, so a whole villa or multi-room fit-out is one project. Each floor has its own plan and scale, each zone its own SPL map and speaker schedule, and the BOQ and PDF report roll every zone on every floor into project-wide totals.
What acoustic analysis does it actually do?
SPL coverage prediction across Low (20–250Hz), Mid (250Hz–4kHz) and High (4–20kHz) bands using coherent phasor summation, axial room modes with boom and null flagged at the listening position, first-reflection points on each wall, L/R stereo imaging angle checked against the 45–60° target, and modelled RT60 for the room volume and absorption.
Is there a 3D view?
Yes. Coverage renders as a relief surface whose height encodes level, with speaker dispersion cones, adjustable room and listening height, a first-person walk mode, and GLB export for use in other 3D software.
How do I create an audio BOQ automatically?
Place speakers on the plan and the tool tracks every product and quantity per zone as you design, adding rack layout and cable lengths from where you place the rack. Export rolls the whole project into one bill of quantities, an Excel quotation that round-trips your prices, and a client PDF report — with no manual line-item entry.
Can I put my own prices and currency on it?
With Pro, yes. Save your standard unit prices once and they apply to every project in any of twelve currencies, shown on the BOQ, the report and the spreadsheet. AI price-list import can read a distributor PDF or Excel straight into matched prices.
Does it work offline?
Simulation and exports run in the browser once the page has loaded. The AI features, account, cloud projects and payments need a connection.
Is it a desktop-only tool?
Effectively yes. Tracing rooms and placing speakers precisely needs a mouse and a wide screen, so phones and tablets get a "best on desktop" notice rather than a cut-down editor.
Does the prediction replace on-site measurement?
No, and it does not claim to. It is a prediction that becomes a verified as-built document once you enter a real RT60 and NC measurement taken on site with the Calibration Toolkit in XSCACE Studio — the measurement mathematically re-drives the simulation.
What is sound simulation software used for?
It predicts how a speaker system will perform in a space — coverage, SPL, room modes and reflections — before anything is installed, so an integrator catches bass problems, dead zones and comb filtering on screen rather than on site after the drywall is closed.
How is this different from REW or Yamaha’s speaker simulator?
REW is excellent at measurement but does no floor-plan design and generates no BOQ. Yamaha's Y-S3 simulates placement but only for Yamaha gear and produces no bill of quantities. This is the only free tool we know of combining acoustic simulation across a real product catalogue, room mode and reflection analysis, and automatic BOQ, quotation and PDF report generation in one workflow.
Used as a speaker placement calculator it works out how many speakers a room needs and where they go. As a coverage calculator it predicts SPL across the floor at listening height, so dead spots show up on the drawing rather than on site. As a ceiling speaker calculator it checks spacing against the coverage angle and the ceiling height. It also lists the room’s axial modes from the traced dimensions, and checks Dolby reference angles against the seating position.
For a single rectangular room, the speaker placement calculator and subwoofer placement calculator do the same arithmetic on their own.
Absorption is set wall by wall — reflective, non-reflective, or a custom absorptivity — rather than as one figure for the whole room, and acoustic panels can be placed into the plan so the coverage map recomputes around the treatment. Enter a measured RT60 and ambient noise reading after commissioning and the same model re-solves against what the finished room actually did.
These are the brands other users have already added. It is not a closed list: any manufacturer’s product can be added by typing its specifications or uploading the spec sheet, and it joins the shared catalogue once moderated.
The catalogue carries more than 136 products from XSCACE and other manufacturers, filterable by brand. Modelling other manufacturers’ products is a paid add-on; everything else in the planner is free to use.
