HTML Background Audio API
Keep HTML audio playing in the background of your iOS WebView app — even when the screen is locked.
For some scenarios, it may be useful to play audio content even after minimizing the app (for example, if you're making a radio stream or your music available in the app).
Our video below shows how to quickly and easily activate HTML background audio for your iOS application, allowing users to play audio even when they switch to a different foreground app or when they lock their iPhone or iPad.
