Design, simulate and compare sound systems with real loudspeaker data.
Draw a room or an open-air site, place loudspeakers taken from official datasheets, and see coverage, SPL, shadows, delays and uniformity — with the equation behind every number.
Build the venue
Indoor or outdoor, stage, audience zones with raked seating, columns, walls and balconies. Top view and a true-scale side section.
Place real loudspeakers
X, Y, Z, azimuth, tilt and roll. Every value comes from a manufacturer datasheet and shows its provenance and the exact quote.
Read the prediction
SPL and coverage maps, shadow zones, headroom over noise, measurement points with per-speaker contributions and arrival times.
Compare options
Swap models in the same scene and weigh the trade-offs. No “best speaker” — options with advantages and limitations.

Data you can trace
…. Values are classified MANUFACTURER, CALCULATED, ESTIMATED or UNKNOWN. When a sheet only publishes 90° × 60°, the directivity is drawn as a labelled nominal geometry — curves are never invented.
Explore the database →No black box
Every model the simulation uses is documented with worked examples and its limits, and backed by automated physics tests.
Read the reference → · Calculators →Predictions are simplified estimates (direct sound, energetic summation, nominal directivity). They do not replace the manufacturer’s own prediction software, room-acoustic modelling or on-site measurement.
