Questions

  • No, you can draw a room and run the full analysis as a guest, no sign-up. You only need an account when you want to save a room and come back to it later.

  • A tape measure is enough. You do not need centimetre precision for treatment to be accurate.

  • Yes. Sloped and vaulted ceilings, attic rooms with angled roofs, and L-shapes are all supported. You can also place doors and windows on any wall and set their size and position.

  • It models the sound field for your exact room and system, then tracks where each frequency band lands on the walls. Panels go where they have the highest measured impact based on frequency response and sound decay times across the entire frequency spectrum.

  • Yes, and it goes further. It can also optimize speaker and listening positions first, searching well over a hundred thousand placement and aiming combinations for the flattest response and the tightest stereo imaging. You can also choose which combination of components to optimize: subwoofer(s), speakers, or listener position.

  • Yes. There is a dedicated studio mode alongside the listening-room workflow.

  • Yes, it does. Each material within the room has its own unique absorption coefficient derived from frontier research.

  • For position searches, anywhere from 2-10 seconds, and for panel placement, up to a minute.

  • 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.
