New HomePod Ambient Sounds and Sleep Timer Features
Version 13.2 of audioOS for the HomePod included two new features that could be useful if your HomePod is in the bedroom. You can now ask Siri to play a collection of endlessly looping ambient sounds, such as Forest, Stream, Fireplace, Night, Ocean, Rain and White Noise. This effectively makes your HomePod a white noise machine, one with amazing speakers. You can also ask Siri to set a sleep timer for these sounds, or any music you are playing.
