Apple has finally bought the popular music-recognition app Shazam and its augmented reality service, according to Business Insider. That said, financial details haven’t been revealed yet. Though numerous reports this week revealed that Apple is expected to pay around $400 million for Shazam. The deal marks Apple’s second biggest acquisitions after Beats in 2014 for $3 billion.

“We are thrilled that Shazam and its talented team will be joining Apple,” said Apple  spokesperson Tom Neumayr. “Since the launch of the App Store, Shazam has consistently ranked as one of the most popular apps for iOS. Today, it’s used by hundreds of millions of people around the world, across multiple platforms.”

She further added that Apple Music and Shazam are a natural fit. Shazam is currently one of the highest rated apps on the App Store, and allows users to discover new music by holding their smartphones near a speaker.

The app recognizes which song is playing, along with the ability to recognize clips from TV shows, movies, as well as classical music. However, in 2015, the app was updated with voice-recognition abilities that further bolstered its popularity and also paved the way for AR.

Apple will likely integrate Shazam with Siri, Apple Music, and iTunes to make its services more appealing to users and help them easily find new music. Siri is already equipped to detect a song the iPhone, iPad, OR Mac, and with Shazam’s integration Siri capabilities can get augmented even further.

Past reports suggest that Apple has been eying Shazam for years now, to use the technology for its own Augmented Reality initiative. Apple recently launched an ARkit for iOS app developers as the company plans to go big on AR. Key sources suggest that Apple has been hiring AR talent and is secretly working on some kind of commercial release.

Even CEO Tim Cook believes that AR is the next big thing, as he talked about AR several times during an earnings call back in July 2016. The Cupertino tech giant is also rumoured to be working on its own wearable device, something on the lines of Google Glass with a focus towards augmented reality.
