Founding developers Lies Zandberg and Robert Lachlan

Lies Zandberg and Robert Lachlan are at the Department of Psychology, Royal Holloway, University of London. Their Cultural Evolution and Communication research group works on communication, bioacoustics, culture and evolution with a focus on bird song. With their tool development research they aim to enable academics, naturalists, and biodiversity surveyors to obtain directional and high-quality acoustic recordings. They push algorithms and circuits to enhance the richness and accuracy of bioacoustics analyses.


This innovative acoustic monitoring device for wildlife integrates beamforming technology. Its sound processing utilizes four MEMS microphones to capture precise and clear recordings. It delivers a 90% higher rate of bird call identification than a single mic device. This cutting-edge technology gets the most out of formerly limited data.
