Pattern Radio: Whale Songs

posted by Jason Kottke   Jun 10, 2019

The National Oceanic and Atmospheric Administration (NOAA) and Google have teamed up on a project to identify the songs of humpback whales from thousands of hours of audio using AI. The AI proved to be quite good at detecting whale sounds and the team has put the files online for people to listen to at Pattern Radio: Whale Songs. Here’s a video about the project:

You can literally browse through more than a year’s worth of underwater recordings as fast as you can swipe and scroll. You can zoom all the way in to see individual sounds — not only humpback calls, but ships, fish and even unknown noises. And you can zoom all the way out to see months of sound at a time. An AI heat map guides you to where the whale calls most likely are, while highlight bars help you see repetitions and patterns of the sounds within the songs.

The audio interface is cool — you can zoom in and out of the audio wave patterns to see the different rhythms of communication. I’ve had the audio playing in the background for the past hour while I’ve been working…very relaxing.
