How researchers use machine learning to re-create chirps and trills produced by forest insects when Dinosaurs lived on Earth

While those sounds have been whipped up by Hollywood sound engineers, scientists are taking the help of technology for a different approach. Crickets and katydids (bush crickets) produce noise via stridulation. Rubbing an opposing wing's scraper across this ridged file sets the wing membrane into rapid vibration. Machine learning algorithms were brought in to process the repetition rates, estimating how fast these extinct species rattled out their core sound pulses.The resulting audio profiles paint an unexpected picture of the ancient night. For example, most Jurassic species trilled in lower tonal registers similar to contemporary crickets.
