Bioacoustics application that gives current temperature readouts by listening to crickets! This app uses the iPhone’s built-in microphone to detect the chirping of Tree Crickets, and computes a temperature value based on the rate of chirping. The readout is usually accurate to within a degree or two.
Sounds from Crickets are captured and put through a “chirp detection” algorithm that computes the number of chirps in 13 seconds and adds that to 40 to come up with the temperature in Fahrenheit.
