New iOS App that tells Temperature by Listening to Cricket Chirps


Sunny Slope Development today is proud to announce that their new iOS app, Cricket Temperature, is now available on the Apple App Store. It is available for iPhones and iPads. This is a fun little app that uses sophisticated algorithms to listen to cricket chirps and calculate the temperature from those chirps. It also displays a plot of the sounds that the device hears. Cricket Temperature also lets people adjust various parameters to see how it affects the signal of the cricket chirps.

This iOS app uses a fast fourier transform algorithm to change the signal from the time domain into the frequency domain, then looks for cricket chips in a very specific frequency region. The algorithm then looks at several frequencies that crickets chirp at and it boosts those frequencies. The app then uses the chirps it hears to calculate the temperature based on the formula of the number of chirps in 14 seconds plus 40. This formula give you the temperature in Fahrenheit degrees. The app displays and immediate temperature and also averages 10 chirp temperatures to display a fairly accurate average temperature.

Cricket Temperature allows children and fun loving adults to explore the world of sound especially crickets by seeing the sound displayed on a frequency plot.

Cricket Temperature 1.0 is only $0.99 USD (or equivalent amount in other currencies) and available worldwide exclusively through the App Store in the Entertainment category.
