Larix Broadcaster for iOS and Android now supports Opus audio over Enhanced RTMP, SRT, and NDI®|HX2. Previously used for WebRTC streaming in Larix, Opus is now available for mobile contribution to streaming servers and for live production over NDI.
Opus is designed for low-delay audio and works well for both speech and music. The new option gives broadcasters more flexibility when sending live interviews, event coverage, or other feeds from a phone or tablet. So in addition to regular bitrates, Larix provides low audio bitrates such as 15, 24 and 32 Kbps.
Before going live, confirm that your ingest server or production software supports Opus over the protocol you plan to use. For Enhanced RTMP in particular, check that the destination supports Opus audio specifically. E.g. Nimble Streamer supports Opus input via all the supported protocols.
You may also set up audio codec and bitrate in Larix Tuner control web service.
