roomtreatment.diy
Free 3D room acoustics solver and acoustic treatment calculator
Design your audio system by choosing speakers and electronics, building your room in 3D, and optimizing acoustics with real room physics.
About this launch
roomtreatment.diy lets you design your entire audio system from the ground up. Choose from real products across speakers, subwoofers, receivers, power amps, TVs, projectors and screens. Build your room in 3D, accounting for odd-shaped layouts like sloped ceilings, attic rooms, L-shapes, doors and windows.
The tool places your speakers and listening position, then searches over a hundred thousand placement and aiming combinations to find the flattest frequency response and tightest stereo imaging. It models the sound field for your exact room and system using real physics, tracking where each frequency band lands on the walls to recommend acoustic panel placement.
You can optimize for listening rooms or switch to a dedicated studio mode for production work. The analysis accounts for what your walls and floor are made of, using absorption coefficients derived from frontier research. Results include frequency response, decay times (RT60), and before-and-after comparisons.

Shopper questions
Do I need an account to use roomtreatment.diy?
No, you can draw a room and run the full analysis as a guest without sign-up. You only need an account when you want to save a room and come back to it later.
Does the tool account for speaker placement and listening position?
Yes. It can optimize speaker and listening positions by searching over a hundred thousand placement and aiming combinations for the flattest response and tightest stereo imaging. You can also choose which combination to optimize: subwoofer(s), speakers, or listener position.
Can roomtreatment.diy handle odd-shaped rooms?
Yes. It supports sloped and vaulted ceilings, attic rooms with angled roofs, and L-shapes. You can also place doors and windows on any wall and set their size and position.
Can it be used for a production studio?
Yes. There is a dedicated studio mode alongside the listening-room workflow.
How accurate is the acoustics model?
The model is built from first principles and acoustics literature, with targets calibrated against measured rooms. It is a prediction rather than a microphone, but it is built to stay as objective as the physics allows.
