Acoustic calculators
Interactive previews of the physics behind the product: standing waves, boundary dips, early reflections and treatment estimates. Fast in the browser; the full solvers live in the 3D room builder.
Room Acoustics Simulator
Draw your room, set up speakers and a seat, and run our wave-based solver on its real shape. See the bass response, modes, RT60 and a 3D pressure view.
Wave-based bass solve · Your real room shape · RT60 and room modes · 3D pressure view
AV Receiver & Speaker Compatibility Checker
Pick your receiver, speakers and layout from real products with sourced specs. See instantly whether the receiver can drive them, and what to change if not.
Impedance check · Channels and pre-outs · Atmos decoding · Power headroom
SBIR & Wall Dip Visualizer
Drag a speaker on the floor plan. Plot quarter-wave cancellation dips from front, side, and rear walls — then hear the null.
Quarter-wave nulls · FR dip plot · Hear the dip · Drag-to-place speaker
First-Reflection Mirror Auralizer
Locate specular mirror points, see early-reflection comb filtering, and toggle a virtual panel to flatten the highs.
Mirror coordinates · Comb-filter plot · Virtual panel toggle · Audio A/B
3D Room Mode Explorer
Browse axial, tangential, and oblique modes to 250 Hz with a pressure heatmap. Drop a desk and check for bass nulls.
