ClapIR Acoustics Measurement Tool

By Stephen Tarzia

Open iTunes to buy and download apps.


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.

What's New in Version 1.1

Made the app compatible with iOS 7. Added Spanish and German language localizations.

Great tool!

I used this to help design my vocal booth while using an untreated room as a control. Works great as far as I can tell. Wanted a tad bit of early reflections and used this app to tell me where I wanted to be as far as adding/subtracting room treatment.

The tool I was looking for !

Thanks a lot for this simple but great tool. It does what it is supposed to do.

You saved my day, thanks again.

With the last guy...

I think maybe an iOS upgrade has rendered this App useless. It doesn't open the mic when the app starts.
