ClapIR Acoustics Measurement Tool


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 available in the iTunes store. This is an open-source project.

ClapIR is based on research done at Northwestern University by Prem Seetharaman and myself, with additional support from Prof. Peter Dinda. For details on the research, please read the AES convention paper.
