How can computers learn to recognize birds from sounds? The BirdNET research project uses artificial intelligence and neural networks to train computers to identify nearly 3,000 of the most common species of North America and Europe. You can record a file using the internal microphone of your iOS device and see if BirdNET correctly identifies the probable bird species present in your recording. Get to know the birds around you and help us to collect observations by submitting your recordings. BirdNET is a joint project of the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology, and Chemnitz University of Technology.
BatLib
This app allows users to listen to and compare the ultrasonic calls of European bats, translated into audible frequencies. It aids in identifying bat species by comparing sounds to output from a BATSCANNER device and provides detailed information about each species.
- Play ultrasonic bat calls in audible range
- Compare sounds with BATSCANNER output
- Filter species by frequency
- Access detailed bat species information
- View photos and habitat details

The BatLib app plays the different ultrasonic calls of most European bats, transformed into the audible range using the heterodyne mixer method. This is particularly useful for comparing directly with the output of the BATSCANNER device to help determine the species. 1. Enter the frequency that your BATSCANNER displays to filter the species 2. Listen to the typical bat call sequences 3. Compare the sound with what you hear from your BATSCANNER 4. Sounds similar? Read additional information about the bat species, such as acoustic characteristics, size, habitat, photos, etc. Further information about our bat products: www.batscanner.ch
