Like so many other tech journalists, I feel as though I've spent the last few years writing the same broad things about Auracast. The tech, which is part and parcel of Bluetooth LE, the new standard that has slowly but surely been spreading through devices in recent years, has been available for a while but seen quite a slow rollout.
The big thing that I've read and repeated over the years is that Auracast could revolutionise how public address systems work. All of a sudden, your Bluetooth device could access shared public announcements in locations like train stations and airports, so that you're never again at risk of missing something important because your music's too loud or your noise cancelling is too effective.
