Floorplan sound simulation software lets an integrator answer a question that used to require a finished install to test: what will this system actually sound like in this room? XSCACE's Floorplan Sound Simulation tool does exactly that — upload a floor plan, trace the rooms, place real XSCACE speakers from the actual product catalogue, and it predicts coverage, bass problems and reflections before a single bracket goes into a wall. It runs free, in a browser, with no account and no install, and it produces the paperwork — a bill of quantities, a branded quotation spreadsheet, and a client-ready PDF report — for every zone of the project, not just one room.
Real Interference, Not a Coverage Blob
Most speaker-placement tools draw overlapping circles and call it coverage. XSCACE's engine uses coherent phasor summation — it models real interference between speakers, the same comb filtering and cancellation that happens in a physical room, rendered as a calibrated heat map with an absolute dB scale rather than a relative “good/bad” gradient. The prediction accounts for each speaker's real sensitivity, power and horizontal/vertical directivity pulled from XSCACE's own product database, distance loss, mounting height relative to ear height, reflections off walls, floor and ceiling using the image-source method, and even furniture — objects absorb, reflect and cast acoustic shadows, weighted by frequency. The map renders across three bands: Low (20–250 Hz), Mid (250 Hz–4 kHz) and High (4–20 kHz), because a system that measures flat at 1 kHz can still have a dead zone in the bass.
Room Modes: Where the Bass Actually Booms
Every rectangular room has resonant frequencies determined by its dimensions — axial room modes that reinforce some frequencies and cancel others regardless of how good the speakers are. The tool calculates these on every axis, four orders deep, and draws both the peaks and the nulls as node lines directly on the plan. That is the difference between a subwoofer placement that sounds huge and one that sounds boomy in one corner and missing entirely six feet away. With the main listening position set, the same engine draws first-reflection points on the side walls — the exact spots where acoustic treatment actually does something, instead of a generic “add some panels” recommendation.
One Project, Every Zone
A project in the tool is structured Floors → Zones, not room-by-room. A whole villa, apartment or commercial fit-out is one file: each floor gets its own uploaded plan image and its own real-world scale, and each zone within that floor gets its own SPL map, room mode analysis, reflection points and speaker schedule. The bill of quantities and the PDF report don't stop at one room — they roll every zone on every floor into one set of project-wide totals, with one report section per zone. That matters for the actual use case: nobody specifies a single-room system and stops, and a tool that only simulates one room at a time turns a whole-home proposal into a dozen separate exports stitched together by hand.
AI Assistance That Gives Coordinates, Not Generalities
The tool reads the uploaded floor plan and detects furniture — sofas, beds, wardrobes, rugs — automatically, then factors those objects into the acoustic simulation as real absorbers and reflectors rather than leaving the room empty. On top of that, an AI acoustic-treatment pass reviews the actual speaker positions, the listening position, and the room's reflection geometry, and returns specific, buildable recommendations. A real example from a 6.4m × 6m stereo room: “Right side wall at x=6m, y=2.37m and y=1.32m (ear height ~1.1–1.3m above floor) — two 60×60cm broadband absorption panels,” and “Rear left corner at x=0–0.5m, y=5.7–6.4m, floor-to-ceiling — vertical corner bass trap.” That is a materials list with coordinates, not a suggestion to “add some acoustic panels somewhere.” The same AI layer suggests amplification and streaming source — Air Mini, Air Amp, or a Xylem DSP amplifier — following XSCACE's real wiring rules, including using a placed Acacia Powered subwoofer's own 2-channel speaker outputs as the zone's amplifier where that's the correct call.
Design It, Then Prove It
A prediction is only as good as the assumptions behind it, and the tool doesn't pretend otherwise. Every zone has a Room Acoustics panel for on-site measurements — a measured RT60 (reverberation time) and ambient noise (NC), taken with the Calibration Toolkit built into the XSCACE Network Controller. Enter that real RT60 reading, and it's mathematically inverted (Eyring) into the room's true average absorption, which then re-drives the entire simulation — the model stops guessing at wall absorptivity and starts using what the room actually measured. The result gets stamped into the report alongside the prediction, so what a client receives is a verified as-built document, not just a forecast. This is the one thing the tool is explicit about not claiming: it does not replace on-site measurement. It becomes accurate once you take one.
3D, and the Paperwork That Wins the Job
The same SPL prediction renders as a full 3D waterfall relief surface — speaker dispersion cones, reflection rays, room-mode visualisation, and a first-person walk mode to stand inside the room before it exists. It exports to GLB for use in other 3D software. But the outcome that actually closes a project is the paperwork: a bill of quantities broken down floor by floor and zone by zone, a branded XSCACE quotation spreadsheet with live line-total and grand-total formulas, and an indexed PDF report with a cover page, a clickable table of contents, one page per zone with its SPL map and technical details, a signal-flow diagram per zone, 3D views, and a phase-based commissioning checklist. An integrator walks into a client meeting with a heat map of the client's actual living room and a priced proposal — not a verbal description of what a system “should” sound like.
