Someone created a website that simulates sonic reflections in a room and detects how acoustic treatment affects them, so you can design your perfect home theater or high-fidelity listening space.



  • The software works with rooms of all shapes and sizes.
  • Helps identify the proper place for speakers and acoustic panels.
  • Free for a room, but furniture analysis requires payment.

If speakers are sonic superheroes, then their archenemies are the rooms we place them in: Poorly placed speakers or oddly shaped speakers can ruin stereo and spatial audio setups by delivering misplaced, boomy, or unfortunate audio. But now a new website offers help finding the perfect place to place speakers and acoustic panels to compensate for unevenness in the room.

The website is Roomtreatment.diy and it uses multiple methods to predict how sound will bounce around your space. You can then identify what treatment is necessary and where it should be placed.

How does Roomtreatment.diy analyze your audio?
