BRIO by OraStream is your personal desktop music server for streaming lossless and high-resolution audio seamlessly, from both within and outside of your home. With BRIO, you can connect your digital music library and play back either locally on your computer or DAC, or wirelessly on Sonos, ChromeCast and uPnP devices.
The BRIO Android app is a companion to BRIO by OraStream. It is used to remotely stream from the BRIO desktop server. Streaming is seamless thanks to OraStream's adaptive bitrate streaming technology.
It also works as a remote control for your BRIO desktop server and allows you to select your desired music source and output.

The Standard Plan, which is free of charge, turns your desktop PC or Mac into a home music server that allows you to access music (at native resolution) stored there remotely using a web browser.
You'd need to sign up for the Mobile Plan to use on the Galaxy S7 to access your home music server.
