## Description

ClapIR is a tool for measuring the acoustic properties of a room.  Simply start the app and clap your hands.  ClapIR then analyzes the clap's recording to calculate the room's reverberation times and frequency response.  It's acoustics engineering made easy!

ClapIR is based on research done at Northwestern University by Prem Seetharaman and Stephen Tarzia.
