Multi-channel audio streaming for production

Stream Bridge can carry up to 16 production audio channels into a browser viewer, giving remote directors, producers and technical teams independent control of programme, clean feeds, commentary, languages, effects and submixes.

4 Simple Steps

  1. Pick a multi-channel feed

    An NDI source carrying up to 16 channels of programme and production audio.

  2. Pair the app

    Install Stream Bridge, add a device on the dashboard and enter its connection key.

  3. Keep channels separate

    Programme, commentary, languages and effects stay as separate channels.

  4. Viewers set their mix

    Each channel can be controlled independently in the browser player.

How it works

A single stereo mix isn't enough for every production role. Stream Bridge can preserve up to 16 source audio channels, so a remote viewer hears exactly the combination they need to direct, approve, monitor or troubleshoot the show.

Channels stay individually controllable in the browser player - programme sound, clean feeds, commentary, languages, effects and technical submixes can all travel with the same low-latency picture, without needing a separate viewer for each mix.

You can also add audio sources that aren't part of the main source, so the viewer's built around the role rather than forcing the source mix to satisfy everyone.

Each viewer still gets its own connection, so plan bandwidth around the video bitrate and the size of the audience. The audio control stays simple for the viewer while you manage the source and access centrally.

Technical Breakdown

A closer look at source channels, browser controls, audio quality, bandwidth, connection handling and viewer configuration.

Supported Sources

Up to 16 audio channels from a single NDI source.

Explore details

With Share All Audio switched on, Stream Bridge exposes the available NDI source channels to the viewer, instead of reducing the production to one fixed stereo choice.

The actual channel content comes from the source - programme, clean feed, commentary, languages, effects and technical submixes can all stay available when they're supplied as distinct channels.

Audio

Independent browser controls for every shared production channel.

Explore details

The viewer can select and balance channels inside the Stream Bridge player, so a director can build a useful monitoring mix without changing the programme mix a client or another viewer hears.

Additional audio sources can also be offered alongside the main source when the required commentary or submix is produced elsewhere on the paired device.

Performance

One video stream with multiple selectable audio tracks.

Explore details

Multichannel delivery is a viewer configuration, not a reason to create a separate video encode for every audio mix - the original picture stays shared while viewers control the tracks made available to them.

Encoding and device limits still apply to the video source. Live CPU and GPU telemetry helps you monitor the whole stream while multichannel viewers are connected.

Viewer Quality & Latency

Production audio stays aligned with the low-latency live picture.

Explore details

Audio channels travel through the same real-time viewer session as the video, keeping production sound useful for directing, approval and technical monitoring.

Browser playback, network stability and the route still affect the final experience. Chrome tends to be the most reliable for WebRTC and multitrack behaviour.

Networking

Individual WebRTC connections for every multichannel viewer.

Explore details

Each viewer gets its own stream connection. Plan sender upload for the video bitrate multiplied by the number of simultaneous viewers, with extra headroom for audio and overhead.

We prefer a direct route and use our cloud relay network automatically when firewall or NAT conditions prevent that connection.

Security & Customisation

Audio choices are configured per viewer link.

Explore details

You decide which links get the full source audio and which get a simpler experience - different audiences don't need to see the same channel selection.

Multichannel links can also use custom URLs, passwords, branding and other player controls, keeping technical monitoring separate from client viewing.

Frequently Asked Questions

Practical answers about source channels, browser mixing, additional audio and bandwidth.

Setup & sources

A viewer can receive up to 16 channels from a single NDI source, when Share All Audio is switched on and those channels are present on the source.

Yes. Shared channels appear as separate controls in the browser, so the viewer can choose and balance the production tracks they need.

No. Share All Audio is part of the stream and viewer setup - separate links can be created for audiences that need a simpler player or different audio options.

Delivery & performance

Yes. Additional audio sources from the paired device can be included on a viewer link, with independent level control in the player.

No. The viewer gets one live video stream with the configured audio choices - you don't need a separate picture encode for every monitoring mix.

Chrome's the most reliable for WebRTC and multitrack playback. Firefox, Edge and Safari are also supported, though behaviour can vary a little between browsers and devices.
