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, 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.

Features
01

Eight Guided Steps, No Manual

Upload a floor plan, trace the room outline, set the scale from a known dimension, place speakers, view coverage, detect furniture, set the listening position, then set the rack. Every step autosaves in the browser, so nothing is lost on a refresh or a closed tab.

Eight Guided Steps, No Manual
02

Coherent SPL Prediction

A calibrated heat map on an absolute dB scale, not a relative coverage blob. Coherent phasor summation models real interference between speakers — comb filtering and cancellation — accounting for directivity, distance loss, mounting height, reflections and furniture absorption across Low (20–250Hz), Mid (250Hz–4kHz) and High (4–20kHz) bands. A drive-power slider runs each speaker anywhere from 0 W to its rated power, and the predicted level moves with it.

Coherent SPL Prediction
03

Cinema Angles

Place the speakers and the plan reads the layout, then overlays the Dolby reference wedges for the front stage, the side and rear surrounds and the height layer — resolving 5.1, 7.1 or Atmos on its own. Set Screen fixes the screen direction, and every surround gets a tick when it lands in spec. A Phantom Centre option models the centre image the L/R pair forms and the seat zone it holds.

Cinema Angles
04

One Speaker At A Time

Alongside the combined coverage map, Speaker SPL renders the predicted field from a single selected speaker on its own — the fastest way to prove a channel reaches the seat, or to find the one driver working too hard. It is mutually exclusive with the combined map, so the picture is never ambiguous about which speakers it is showing.

05

Room Modes, Reflections & Imaging

Axial room modes from the traced geometry, with boom and null flagged at the listening position. First-reflection points drawn on each wall. And an L/R imaging tool that draws the stereo triangle and checks the subtended angle against the 45–60° target — green when it works, amber when the pair or the seat needs to move. Every zone now carries this into the report as its own page: the axial null-line grid over the plan, modal frequencies for length, width and height, the Schroeder transition, and plain-English guidance on where to keep the sub and the seat.

3D Waterfall View

The room in three dimensions with coverage rendered as a relief surface whose height encodes level, plus speaker dispersion cones, adjustable room and listening height, a first-person walk mode, and GLB export for use in other 3D software.

Design It, Then Prove It

Enter a measured RT60 and ambient noise (NC) taken on site with the Calibration Toolkit in XSCACE Studio, and the measurement mathematically re-drives the whole simulation. The prediction becomes a verified as-built document with the measured values stamped into the report.

Design With Any Brand

The full XSCACE catalogue is built in — Slim Array, in-ceiling, in-wall, outdoor, subwoofers and electronics. With Pro you can add any manufacturer’s product: type the specs, or upload the spec sheet and let AI extract the sensitivity, power and dispersion the simulation needs. Added products join a shared community catalogue.

Several Amplifiers Per Zone

A zone can be driven by more than one amplifier — a Lucifer 8 for the bed layer and a Lucifer 4 for the heights, each with its own quantity. Every amplifier flows through to the bill of quantities and the signal flow. Powered subwoofers can drive the satellites themselves, using the Acacia's two-channel output or the Banyan Pith's mono output.

Music Or Cinema, Per Zone

Every zone is tagged as Music & Multiroom or Home Cinema, and that one choice reshapes the exported report. A music room gets a single combined SPL coverage map with the stereo imaging angle and the first-reflection count at the seat. A cinema gets a page per channel group — Front L/C/R, surrounds, rears, the height layer — each mapped from only its own speakers, because surrounds and heights fire individually rather than summing into one field the way a stereo pair does. The Dolby angles, screen bearing and seat position are written in.

Bill of Quantities & Client Report

A bill of quantities built as you design, broken down per floor and per zone with product thumbnails, plus rack layout and cable-length estimation. Cable is tallied by the gauge you pin to each speaker — 12, 14 or 16 AWG, or left automatic. Export to Excel, fill in prices, re-import — it round-trips cleanly by a hidden ID column. The client PDF carries cover, per-zone coverage plans, room modes, technical detail, 3D views and your branding.

Price Lists in Twelve Currencies

Save your standard unit prices once and they apply to every project, in any of twelve currencies, shown on the bill of quantities, the report and the spreadsheet. Prices default to US dollars and follow whichever currency the price list is in, rather than assuming one. AI price-list import reads a distributor PDF or Excel straight into matched prices.

Price Lists in Twelve Currencies
One project. Every zone.

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.

The Workflow

Floor plan to priced proposal.
Eight steps, one tool.

01

Upload floor plan

PNG, JPG or WEBP — drag onto the window or browse. One plan per floor.

02

Trace room outline

Click the corners to define each zone. Vertices are editable afterwards.

03

Set scale

Click two points of a known distance, enter it in metres or feet. Everything downstream is real-world accurate.

04

Place speakers

Drag from the real XSCACE catalogue. Speakers snap to walls, rotate freely, and can be set as ceiling-mounted.

05

View coverage

The SPL map — a calibrated heat map of what the system will actually sound like.

06

Detect furniture

AI reads the plan and finds sofas, beds, wardrobes, rugs — they block and absorb sound in the simulation.

07

Set MLP

The main listening position, which drives reflection analysis.

08

Set rack

The head-end location, from which all cable runs are estimated.

Design → Measure → Verify

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.

The prediction becomes a verified as-built document. Not a claim that it replaces on-site measurement — a tool that gets more accurate once you take one. The measured values are stamped directly into the report, alongside the XSCACE Studio that produced them.

Frequently Asked Questions
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.
