An anonymous reader shares a report from VentureBeat, written by Emil Protalinski: The most interesting Google Pixel 2 and Pixel 2 XL feature, to me, is Now Playing. If you've ever used Shazam or SoundHound, you probably understand the basics: The app uses your device's microphone to capture an audio sample and creates an acoustic fingerprint to compare against a central song database. If a match is found, information such as the song title and artist are sent back to the user. Now Playing achieves this with two important differentiators. First, Now Playing detects songs automatically without you explicitly asking -- the feature works when your phone is locked and the information is displayed on the Pixel 2's lock screen (you'll eventually be able to ask Google Assistant what's currently playing, but not yet). Secondly, it's an on-device and local feature: Now Playing functions completely offline (we tested this, and indeed it works with mobile data and Wi-Fi turned off). No audio is ever sent to Google.
