This app REQUIRES a JackTrip Analog Bridge or JackTrip Digital Bridge. Use the JackTrip mobile app to register your JackTrip Bridge, and then visit https://app.jacktrip.org to get connected. Sing with your chorus, or jam with your band without leaving home. JackTrip is a tool for musicians that enables them to produce music together over common Internet connections. It delivers high quality sound with minimal time delay, so that musicians can keep the beat and stay in harmony. It can make it sound like you are in the same room next to each other, even when you are actually hundreds of miles apart.
