This website is about acoustic measurements of loudspeakers in rooms, for audio professionals but also for amateurs. You don’t need any software or knowledge to do the measurements but thanks to very complete results and graphs, even professional get all needed informations to understand and improve the measured audio systems. A FIR correction can also be automatically calculated for FIR processors (ie MiniDSP, streaming softwares,…).

You can start having a look at the All measurements page and compare performances of various systems..
For measuring, you need to register (it’s free) to access to the Upload recording where you can start with a free test. You just have to download and play the audio file and record with a microphone, preferably calibrated.
