Broadcast Transmission and Syndication

Reliable audio streaming from broadcast studio  to studio or to the transmitter site.


Broadcast audio codecs

Professional Multiprotocol IP Audio de-/encoder with I/O, balanced audio. Support of Internet Radio and VoIP (SIP, RTP) codecs and protocols make the products the ideal choice for broadcast, professional and VoIP applications. Remote contribution links with SIP in combination with the high-quality, open audio format Opus creates a cost-effective solution. SIP functionality can establish seamless links across VoIP and other IP based communications systems, making it ideal for remote contribution applications. This makes this application particularly interesting when using remote contribution back to the studio, such as from sporting events.

No hassle broadcast link management

Reflector is a complete solution for streaming audio that replicates a received stream to an unlimited number of destinations through the public internet. The solution is based on a server-client architecture. The client encoder device pushes the audio stream to the server and the client decoder devices pull the stream from the server. The client devices don’t need to have a public IP address and don’t need any specific configuration for passing through. The number of receiving locations is only limited by network bandwidth.

All client devices are configured automatically on startup from the server where they are registered with their MAC address. Thus the devices can be shipped directly to their locations, and no manual intervention is needed for configuration. Depending on the chosen hardware devices, it is also possible to pass contact closure information in the same stream. At the destination a failover to USB playback can be used to ensure a continuous audio feed out in case of network failure. A free iPhone App is also available to monitor the audio streaming. The Reflector Service itself can be hosted by the Barix partner StreamGuys, or the server software can be licensed for own management. 

Streaming audio to an internet radio provider (Icecast, Shoutcast)

Convert any audio signal into Shoutcast, IceCast, G.711, PCM or high-quality MP3 streams and send the stream to up to 32 different destinations across the LAN or over the internet. Supporting peer-to-peer connections with other Barix devices, it can also be used for integration into wide audio infrastructures. With the BRTP protocol the application can communicate with other Barix devices on secured networks. Easy-to-install and cost-effective solution for professional audio streaming.

High quality audio transport using SIP

Barix’new MA400 SIP Opus Codec enables remote contribution links with SIP and the high-quality, open audio format Opus in a cost-effective solution. The advantages of the royality-free Opus codec are its quality, efficiency and low latency. Combined with the SIP functionality to establish seamless links across VoIP and other IP based communications systems, it is ideal for remote contribution applications. The SIP functionality in the Barix unit allows to dial another device or auto replies to a call and automatically negotiate a transmission link for Opus based audio streaming. Particularly interesting is the MA400 SIP Opus Codec for remote contribution back to the studio such as from sporting events.
