Fantoni Bluesound app for iPhone and iPad
Bluesound by Fantoni enables you to measure reverb time in closed spaces using the microphone on your phone. Enter the dimensions of the room and select the type of use; the app will give you an estimated reverb time (RT60) and simulate the acoustic effect of the different Fantoni sound-absorbent systems. The results given by the app, while realistic, are for guidance only.
