Last october, Endel announced that he partnered with Grimes to create a special “ soundscape ” in his music app, meant to help you focus, relax, or fall asleep. The collaboration was called AI Lullaby, and as you might have guessed from the name, combined artificial intelligence with original Grimes music and vocals. There was just one problem: it was only available on iOS. Sleep sounds are now gone for iPhone users and, as promised, have moved to Endel’s Android app. If you have a phone or tablet that works with Google’s operating system, it should be accessible the next time you open the app.
So what makes Endel special? And why can’t these soundscapes work on a platform like YouTube? Well, Endel is all about personalization. It takes into account many factors, such as the time of day and your body’s circadian rhythms. If you’re feeling generous, you can also provide the app with more data, such as your location – which covers the weather and the amount of sunlight outside – heart rate and movement in general. Endel then uses this information to generate and play music that uses pure intonation and pentatonic scales, which are easily absorbed by the brain. The company also uses “sound masking” techniques to bury hard elements.
Grimes, meanwhile, teamed up with Endel after researching “a better baby sleep situation for her son, X Æ A-XII Musk.” “When you have a baby you always use white noise machines,” Grimes Told The New York Times. “It’s a lot easier to put them to sleep if you train them in some sort of audio situation. And so I was like, could this be more artistic?
