'Wavelet' Math Translates Whale Song into Art

摘要

Wavelets, they're called, but they're not the kind that gently lap onto shore. These wavelets create a kind of science-art, one that depicts the haunting songs of whales and dolphins.rnIn this setting, wavelets are mathematical functions that parse data into different frequencies. "They have advantages over other methods of analyzing signals with sharp spikes," says Mark Fischer. Such spikes, he says, are characteristic of whale and dolphin music.
