To mix audio remotely for a live stream, first decide whether you mean controlling a mixer at the venue from elsewhere or sending audio over a network to a remote mixing position. In either case, map the signal path, make a clean program mix for the audience, and monitor the signal that actually reaches OBS. If remote guests need to hear the show, give each guest a separate mix-minus return that excludes that guest’s own incoming audio.
Choose the remote workflow before routing audio
“Remotely mix” describes two different setups. They solve different problems, so identify where the audio is mixed before choosing network, software, or hardware.

| Workflow | Where the audio is mixed | What travels over the network | Best fit |
|---|---|---|---|
| Remote control of a local mixer | At the venue, on a physical mixer or local computer | Control commands and status; audio can remain local until it enters the streaming computer | You need to adjust a venue mix from another location and the mixer supports secure remote control. |
| Networked audio transport | At the operator’s remote location, or in a remote software workflow | Audio channels or a mix from the venue to the mixing position, and possibly a return feed | The audio itself must travel to another location for mixing or production. |
Do not assume a remote-control connection carries audio, or that an audio transport provides mixer controls. Confirm what the specific mixer, interface, driver, and application can send and receive.

Draw the signal path and identify each mix
Write down the route from every source to its destination before opening OBS. A basic livestream path is:
#1 Best Overall
- [XLR Mic Input] One XLR microphone input interface is set on the gaming audio mixer, which is great to up your audio quality with your XLR setup. The XLR mixer is a stepping stone to upgrade your live streaming. Audio mixer offered built-in 48V phantom power which opens up more choices for mics. Directly use it with your condenser microphone but do not solve added peripherals. (NOT available for USB mic)
- [Individual Channel Control] Gaming audio mixer for one mic recording with smooth volume slider fader take your streaming recording to a whole new level with full pleasure. Four independent channels set on the DJ mixer give audio volume of the MICROPHONE, LINE IN, HEADPHONE, and LINE OUT channels individual control. Configurable on the PC audio mixer instead of just operating on your game or streaming software.
- [Mute and Monitor] The front mute and monitor buttons but not at the back, make it easier to get the audio interface use. Ability to mute audio, the audio mixer for streaming prevents background noise from damaging your live broadcast. Real-time feedback between speaking and hearing will not distract your attention, which encourage you to speak more confidently. The sturdy-built control button allow you to operate freely and easily during live streaming.
- [Sound Effects] The computer sound mixer supports four pre-recorded customized button that can be recorded and activated at the press of button to post production. 6 kinds of voice changing modes change your output style. 12 auto tune changes the tone of your voice. The podcast mixer being able to add different and fun effects is a huge bonus for your streaming or game voice.
- [Controllable Vibrant RGB] RGB button on the audio mixer DJ meets different live streaming themes. Lights on the video mixer is vibrant but not harsh on your eyes. Flowing or frozen RGB color rotation in a decent pace presents a greatly strong impression as a "light show" to your audience. Even a streaming equipment accessory will not be dull looking when video production.
Microphones and playback sources → mixer or audio interface → program mix → OBS or encoder → streaming platform
If there are remote guests, add a second path: host and selected show audio → guest-return mix → call or contribution app → guest. The guest’s incoming audio should feed the program mix, but not their own return.
- Program mix: what the audience hears, including the host, relevant playback, and remote guests.
- Guest return: what a particular guest hears. Include the host and any other sources they need; exclude that guest’s own incoming channel.
- Monitoring path: what the operator listens to while checking the mix. Monitor the same bus or signal point that feeds the stream when possible.
With more than one guest, plan a separate return for each person if each must hear everyone except themselves. A single shared return cannot remove a different guest channel for each participant.

Get the local mix into OBS
1. Confirm the source before adjusting OBS
Start at the microphone, playback source, mixer, or interface. Check its physical gain or software level and confirm that the intended input is active. OBS’s Audio Mixer Guide, published April 3, 2026, recommends checking from the source device and listening through Audio Monitoring as well as watching the mixer.
2. Route the intended program bus
Choose an output that carries the program mix, not an isolated microphone or an unintended monitor feed. Depending on the setup, that may be a physical mixer output, an interface input, or a virtual output provided by compatible software. Do not assume every interface offers loopback, virtual outputs, or independent buses; check its driver, operating-system support, channel routing, and ability to create any guest returns you need.
One documented example is PreSonus’s Revelator Dynamic livestream setup: configure its software mixer and send “Stream Mix A” through a virtual audio output to OBS. This illustrates virtual routing for that product; it does not establish that other interfaces work the same way.
Rank #3
- Compact, feature-rich livestreaming USB audio mixer provides high-quality sound for desktop audio production
- Plug-and-play connectivity to computer or mobile device (no special drivers required)
- Loopback function makes it easy to mix mic and instrument inputs with background music, game sounds, or other audio input from a computer – and send the stereo mix back to the computer for streaming
- High-performance A/D converter with resolution up to 24-bit/192 kHz provides crystal-clear output for voice and instruments
- Equipped with a single mic input (XLR or ¼"), two LINE inputs for guitar and keyboard, and USB-C input for connecting to a computer
3. Select and monitor the input in OBS
Add or select the audio source connected to the program bus, then use the OBS Audio Mixer to confirm its meter responds when expected. Use the source’s monitoring controls to listen to the signal in OBS and verify that it is the complete mix you intend to stream. A meter shows level, not whether the right bus or sources are routed.
OBS’s Audio Mixer Technical Details, published February 13, 2022, explains that 0 dBFS is the maximum digital level and exceeding the output ceiling can cause clipping distortion. Keep the signal clean at the source and through the OBS input; do not let peaks reach or exceed that ceiling.
Build a mix-minus for remote guests
A mix-minus sends a guest the useful parts of the show while omitting that guest’s own incoming audio. Without that exclusion, the guest can hear their voice return after transmission delay, creating an echo or other distracting repeat. The stream still receives the full program mix, including the guest.

- Create the guest-return bus. Include the host and the other show audio the guest needs. Leave out that guest’s incoming channel.
- Choose the return as the guest app’s microphone or input. In the call or contribution software, select the bus that carries the mix-minus—not the full program mix if that mix includes the guest.
- Bring the guest’s received audio into the program mix. Select the call app’s guest audio output as a source for the stream mix.
- Check both directions. Confirm that the guest can hear the host and relevant show audio, cannot hear their own delayed voice, and that the audience feed includes the guest.
- Repeat the check per guest. Where separate returns are needed, each return must omit its own recipient’s incoming channel.
Keep the return from feeding back into itself. If the call app, mixer, or interface cannot provide an independent bus or input/output selection, it may not support the mix-minus routing this setup requires. The Critical Listening Lab mix-minus explainer also describes the underlying routing idea.

Networked audio can help when audio must reach a remote production position, but evaluate the full path: capture, transmitter, network, receiver, application buffers, mixing, monitoring, and any return path. A transmitter’s latency figure is not the same as the delay a guest experiences in a complete two-way conversation.
NDI’s Technical Facts About NDI for Audio (copyright 2024) states that an NDI audio transmitter can deliver a stream over a network in 6 ms. The same documentation cautions that this may not be suitable when a captured microphone is monitored in the same environment. That 6 ms is a network-delivery figure, not a guaranteed end-to-end round trip through a call, mixer, buffers, and monitoring. The document also identifies 48 kHz as the standard sample rate for live production; treat that as NDI’s stated live-production standard, not a universal requirement for every system.

NDI’s audio use cases include live streaming, broadcast, and remote production, while noting 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 intended to send and receive NDI audio in software workflows, including virtual or cloud environments. It is an option for compatible systems, not a universal substitute for a local interface or a dedicated audio-over-IP system.
Before adopting a network transport, verify channel count, network reachability, application and operating-system compatibility, routing, monitoring delay, synchronization needs, and how the system recovers if the network fails. The available documentation does not establish a controlled head-to-head result for specific audio protocols or products.
Check the mix before going live
- Speak or play audio into each source and verify it reaches the intended program bus.
- Listen in OBS to the stream-bound signal, not only to a mixer’s local monitor.
- Check the program mix and each guest return independently.
- Ask each guest to confirm what they hear, then confirm that the audience feed includes the guest without routing their voice back to them.
- Watch for clipping at the source and in OBS; meters alone cannot confirm correct routing or clean sound.
- If using network transport, check synchronization and delay at both ends using the complete real-world path.
Troubleshoot common routing failures
| Symptom | Likely cause | What to check |
|---|---|---|
| OBS meter does not move | The wrong device or output is selected, the source is muted, or the mixer is not sending to that output. | Follow the signal from source to bus to interface or virtual output, then confirm the matching input is selected in OBS. |
| OBS shows a level, but the audience cannot hear the intended mix | OBS is receiving a different bus, or one or more sources are missing from the program mix. | Listen through OBS Audio Monitoring and check the source assignments on the bus feeding the stream. |
| A guest hears their own delayed voice | The guest’s incoming channel is included in their return, or the return is routed back into itself. | Remove that guest channel from their return and verify the call app’s selected input and audio routing. |
| The audience hears the guest, but the guest cannot hear the host | The guest-return bus is missing the host, or the wrong input is selected in the call app. | Add the host to that guest’s return and select that bus as the app’s microphone or input. |
| Audio distorts on stream | The signal is clipping at the source, in an intermediate device, or at the OBS output ceiling. | Check gain and level at each stage; OBS identifies 0 dBFS as the maximum digital level. |
| Networked audio feels out of sync or uncomfortable to monitor | The total application, buffering, network, and monitoring delay may be greater than the transport figure alone suggests. | Assess the complete path and use case; do not treat a transmitter latency number as a round-trip guarantee. |
| A virtual output or separate return is unavailable | The interface, driver, operating system, or application may not provide the required routing. | Check the product’s supported virtual outputs, loopback, independent buses, and compatibility before rebuilding the workflow around it. |
