Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →To mix audio remotely for a live stream, first decide where the mix will be made: at the venue on a mixer you control over a network, or at your location from audio transported to you. Then map each signal from its source to the stream and, if guests need a return, create a separate mix-minus bus that leaves each guest out of their own return. Check the actual audio reaching OBS by listening to it, not just by watching meters.
Choose what “remotely mix” means for your setup
These workflows solve different problems. Remote control changes settings on a mixer located elsewhere; network transport sends audio from one place to another so it can be mixed at the receiving end. A setup may use both, but neither is simply a matter of opening OBS from a distance.
| Workflow | Where the mix is made | What to plan for |
|---|---|---|
| Remote control of a venue mixer | At the venue, on its mixer | Network access to the mixer’s control system, someone or something to manage the local signal path, and a way to monitor the resulting program feed. |
| Networked audio transport | At the receiving location, after audio arrives over the network | Transport latency, channel count, routing, monitoring, synchronization, and what happens if the network or receiving application fails. |
| Local mix into OBS | At the streaming computer, on a hardware mixer/interface or in software | A defined program mix routed into OBS, with a separate return bus if remote guests need to hear the show. |
For a documentary interview or discussion, draw the path before choosing tools: microphones and playback sources → mixer or software routing → program mix → OBS → streaming platform. Add a distinct guest-return path when participants are joining remotely. This reveals whether the challenge is controlling a distant console, transporting audio, or simply routing the right mix to OBS.
Build the program path into OBS
- Identify every source. List each microphone, playback source, and remote participant. Note where each signal enters the system and which person needs to hear it.
- Choose the program bus. Combine the sources intended for the audience into one program mix. If the interface or mixer offers virtual outputs or loopback, verify that the selected output carries this mix and not an unintended input or monitor bus.
- Route that output into OBS. Select the corresponding device or virtual output as the OBS audio source. PreSonus documents one example using its Revelator Dynamic software mixer: “Stream Mix A” is sent through a virtual audio output to OBS. This is an example, not proof that other interfaces provide the same buses or routing. Check the actual device’s drivers, operating-system support, outputs, and independent-mix capabilities. See [PreSonus’s OBS setup example](https://support.presonus.com/hc/en-us/articles/5338093881101-Revelator-Dynamic-Set-up-livestream-in-OBS).
- Check the input at the source and in OBS. Start with the microphone or playback device’s physical gain or software level. Then check the signal entering OBS and listen to it through OBS Audio Monitoring. OBS’s [Audio Mixer Guide](https://obsproject.com/kb/audio-mixer-guide) covers its source meters, faders, mute, and monitor controls.
- Keep the digital output clean. OBS identifies 0 dBFS as the maximum digital level; signals exceeding the output ceiling can clip and distort. Avoid peaks at or above that ceiling. A meter can show activity while the wrong bus is routed, so listen to the same program path the audience will receive. See [OBS’s audio technical details](https://obsproject.com/kb/audio-mixer-technical-details).
If the stream sounds wrong, check the whole chain in order: source gain, mixer or software bus, selected OBS device, OBS source mute and fader, then the stream output. Changing an OBS fader will not correct a misrouted bus upstream.

Send remote guests a mix-minus
A remote guest needs to hear the host and relevant show audio, but a return containing that guest’s own voice can send it back with delay. A mix-minus is a separate return mix with the guest’s incoming channel removed. The audience program mix still includes the guest.
- Create the guest-return bus. Include the host, other desired participants, and relevant playback. Exclude that guest’s incoming audio.
- Set the call or contribution app’s microphone input. Choose the guest-return bus as the app’s input, rather than the complete program mix.
- Route the guest’s incoming audio to the audience mix. Select the appropriate call-app output as a source in the stream’s program mix so viewers hear the guest.
- Test both directions. Confirm the guest hears the host and intended show audio, does not hear their own delayed voice, and is audible in the program mix. Do not route the guest-return bus back into itself.
With multiple guests, each may need a distinct return that excludes that individual guest. Whether a particular interface, mixer, or application can create the required independent buses depends on its actual routing features. A secondary explanation of the routing concept is available from [Critical Listening Lab](https://www.criticallisteninglab.com/en/learn/streaming-setup/mix-minus).

Transport audio over a network with latency in mind
Network audio can support live-streaming and remote-production workflows, but judge delay across the whole path: capture, transmitter, network, receiving application, buffers, mixing, monitoring, and any conferencing return. A transport’s latency figure is not the same as an interactive end-to-end round trip.
NDI/Vizrt’s [technical facts for NDI audio](https://docs.ndi.video/all/using-ndi/ndi-for-audio/technical-facts-about-ndi-for-audio) state that an NDI audio transmitter can deliver a stream over a network in 6 ms. That figure describes transmitter delivery, not a guaranteed guest round trip through applications and monitoring. The same documentation cautions that this may not suit someone monitoring a captured microphone in the same environment. It also identifies 48 kHz as the standard sample rate for live production; treat that as the cited documentation’s stated standard, not a universal requirement for every system.

NDI’s [use cases](https://docs.ndi.video/all/using-ndi/ndi-for-audio/use-cases) include live-streaming, broadcast, and remote production, and note that some commentary or production settings can tolerate latency when synchronization is not a blocking issue. NDI Audio Direct is a collection of VST plugins for Windows DAWs for sending and receiving NDI audio in software workflows, including virtual or cloud environments; see [Audio Direct documentation](https://docs.ndi.video/all/using-ndi/ndi-tools/plugins/audio-direct). It is an option for compatible setups, not a universal substitute for a local interface or dedicated audio-over-IP system. Confirm channel count, network reachability, routing, monitoring delay, and recovery behavior in your own configuration.
Check the setup before going live
- Trace the signal: Confirm that every intended mic, playback source, and guest reaches the program bus and that the bus selected in OBS is the intended one.
- Listen at the stream end: Monitor through OBS and confirm you are hearing the same mix sent to the audience.
- Verify guest routing: Test the guest’s return and stream contribution separately; make sure the return excludes that guest and is not feeding itself.
- Check practical latency: Evaluate the complete path in context, especially if a person is monitoring a microphone in the same room or holding a live conversation.
- Confirm compatibility: For virtual routing or network audio, verify driver and operating-system support, channel count, independent buses, and the applications’ actual input/output choices.
- Plan for a failure: Establish what you will do if the network, receiving application, or remote-control connection drops. The cited material does not establish a universal recovery method; it depends on the equipment and topology.
Common problems and what to check
| Symptom | Likely cause | Check or fix |
|---|---|---|
| OBS meters move, but the stream has no wanted audio | The wrong source or bus is selected, or the intended source is muted. | Listen through OBS Audio Monitoring; verify the selected device, source mute, and upstream bus routing. |
| Audio distorts on the stream | The signal exceeds the digital output ceiling. | Check level at the source and again where audio enters OBS; avoid peaks at or above 0 dBFS. |
| A guest hears their own voice delayed | The guest’s incoming audio is included in their return. | Use a guest-return mix that excludes that guest, and ensure the return does not feed itself. |
| A guest hears the host, but viewers cannot hear the guest | The guest return is configured, but the guest’s incoming output is not included in the program mix. | Route the call or contribution app’s appropriate output into the audience mix and test it independently. |
| Remote monitoring or conversation feels delayed | The complete route adds more delay than the transport figure alone suggests. | Check the end-to-end path, including application buffers and monitoring, and decide whether that delay is acceptable for the use case. |
| A virtual output or separate return is unavailable | The interface, driver, operating system, or application may not support that routing arrangement. | Check the device’s documented loopback/virtual outputs and independent-bus support; consider a mixer/interface that provides the required paths. |
