SIP Opus Codec

SIP link negotiation protocol based Codecs for audio over IP transport.

The cost-effective new MA400 and M400 SIP Opus Codecs combine the dynamic flexibility and ease of SIP-based link establishment with the quality and efficiency of the open Opus audio compression format. The SIP Opus Codec devices encode or decode audio signals using the open standard Opus codec, a royalty-free audio compression format known for exceptional quality and reliability in interactive speech and music transmission over the Internet. 

The devices build on the Opus codec’s quality, efficiency and low latency with SIP functionality to establish seamless links across SIP-compatible telephone or other IP-based communications systems. Ideal for remote contribution applications, the SIP functionality in the Barix units enables them to dial another device or accept an incoming call and automatically negotiate a transmission link for Opus-based audio streaming. In addition to remote broadcast links, the SIP Opus Codecs offer a reliable, high-quality solution for studio-to-studio (SSL) and studio-to-transmitter (STL) applications at cost-efficient pricing.

Built on Barix’s latest-generation, high-performance IPAM 400 audio module, the SIP Opus Codec devices are available in two powerful models. The mono, bi-directional MA400 SIP Opus Codec is powered by PoE and features analog microphone or line-level input and 5W 8-ohm or line-level output. Meanwhile, the stereo, externally powered M400 SIP Opus Codec can be configured as either an encoder or a decoder, and offers line-level analog input or output with RCA connections. The M400 also supports directly connected USB microphones. Both models support audio level supervision with SNMP trap generation and interoperate easily with third-party SIP-compliant, Opus-compatible products.
