Broom room

Browser-based room impulse response measurement.


Sweep the room

What it's all about.

Use the power of the Web Audio API to capture Room Impulse Responses... in the browser! This web app uses a sine sweep to excite the room. The microphone captures the response of the room you want to measure. This Sweep Response is then processed to an Impulse Response, ready for you to download.

Please note: this project is in its very early stage and is still work in progress. So there might be some bugs and the results may even differ between browsers.
