Quite often there is a need to stream from a PC to Barix devices. As Barix devices use standard IP streaming protocols any third party SW can be used to achieve the goal. The most convenient and most standard way is to have MP3 audio streaming in RTP protocol.
MP3 RTP Streamer
MP3 RTP Streamer is an interactive Java tool developed by Barix, that can run on Windows, Linux or MAC.
VLC Media Player
As alternate option the VLC Media player can be used. The VLC Media Player is freeware from the internet and allows to stream audio files, playlists and the PC audio inputs (e.g. line & microphone) over network to other targets, e.g. to the Barix Exstreamer.
Please check the Barix VLC Media Player - Howto  for more details.
