AudioHallo – Church Audio

Hard to hear the sermon? AudioHallo brings the church's sound system straight to your phone and earphones over the church's own Wi-Fi. • Simple: large text, big buttons, one tap to listen • Fast: the sound arrives with almost no delay, in sync with the speaker • Automatic: the app finds the church's audio server by itself • Clearer speech: an optional switch brings voices forward and lifts quiet words • Text on the screen: when the organisers send a short text, such as the hymn number, it appears at the top of your screen • Translation: if the church streams more than one channel, switch with one tap • Mute ringing while you listen, if you like; it switches back when you stop • Home screen button: start the church sound with one tap • Keeps playing with the screen off; big volume buttons, or the phone's own • Works on church Wi-Fi without internet; your mobile data keeps working • Follows your phone's language (English, Hungarian, Romanian) and dark mode • Free, no sign-up, no ads, no tracking Requires an AudioHallo system at the church: a Raspberry Pi or Windows computer with a USB sound card connected to the mixer, and a Wi-Fi router. Wired earphones give the best result; Bluetooth earphones add about 0.2 seconds of delay.
