StreamLive ProEcho during a live stream with guests
Echo in a live with guests usually comes from someone using speakers instead of headphones, or watching the live in another tab. How to find who and fix it.
Echo in a live with guests almost always has one source: someone's microphone is picking up the sound from their own speakers. A guest listens on laptop speakers, your voice comes out of them, their microphone catches it and sends it back, and now everyone hears you twice. The second common source is a guest, or the host, who has the live stream open in another tab: the delayed broadcast plays out loud and goes back into the microphone.
StreamLive Pro already prevents the classic echo. Each guest receives their own mix: you and the other guests, without their own voice (this is called mix-minus). The browser's echo cancellation is also turned on for the host microphone. What software cannot fully remove is sound that leaves a speaker and comes back into a microphone in the same room.
Symptom, cause, fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Everyone hears the host twice, a moment apart | A guest is on speakers, not headphones | That guest puts on headphones, or you mute them while they are not talking |
| The echo stops when one guest is muted | That guest's microphone hears their speakers | Headphones for that guest |
| A long delayed echo, several seconds | Someone has the live playing in another tab or on a TV | Close the live on that device, or mute it |
| Echo only when two people sit in the same room | Two devices with open microphones near each other | One device per room, or headphones and one muted mic |
| Echo from the host side | The host monitors the program or a guest on speakers | Host on headphones; choose them in "Select speaker for guests" |
| You use a multi-input sound card and hear echo | The browser's echo cancellation is off for such devices | Use headphones for monitoring |
Steps
- Find the source by muting. In the participant row of each guest, mute them one at a time. When the echo stops, you found the microphone that is picking up speaker sound. Every mute is shown to the guest, so they know it was you.
- Ask that person for headphones. Any wired or wireless headphones stop the loop. This is the fix that works every time.
- Close extra copies of the live. Ask guests not to watch the stream on YouTube or Facebook while they are in the room. The room already gives them everything they need to hear.
- One device per room. If two people sit together, use one computer with one microphone, or give each headphones and keep only one microphone open.
- Put the host on headphones. Use the "Select speaker for guests" button in the live studio (in the Podcast studio: the audio output button) and choose your headphones, so guests are heard only in your ears.
- Check multi-input sound cards. If your microphone runs through a sound card with several inputs, StreamLive Pro opens it without the browser's voice processing so that each input can be routed. That includes echo cancellation, so monitor on headphones.
- Test before you go live. Join with one guest, talk for ten seconds each, and listen. It is easier to fix echo before the broadcast than during it.
Why guests do not hear themselves
Each guest gets their own audio mix without their own voice, and a mute you apply to a guest also enters that mix. That is why echo in StreamLive Pro is almost always acoustic: sound from a speaker in a room going back into a microphone in the same room.

When to contact support
If everyone, host included, wears headphones, nobody has the live open elsewhere, and the echo stays, write to [email protected]. Send the broadcast or room time, how many guests were in the room, which studio you used (live or podcast), and a short recording of the echo if you have one.
If the problem is the opposite, that you cannot hear a guest at all, see I cannot hear my guest in the live stream.
Frequently asked questions
Why is there echo when StreamLive Pro has echo cancellation?
Echo cancellation and the per-guest mix handle the sound inside the call. Sound that comes out of a speaker in a room and goes back into a microphone in the same room cannot always be removed. Headphones stop it.
Who has to wear headphones?
Whoever's microphone is picking up speaker sound. The quick way to find them is to mute guests one by one until the echo stops.
Can a guest watch the live on YouTube while being a guest?
Better not. The delayed broadcast playing out loud goes back into their microphone. Everything they need to hear is already in the room.
Does the echo get into the recording too?
Yes. Echo that is in the room's sound is also in what goes out to the networks and into the recording.
Can I mute a guest without them leaving?
Yes. Each guest has mute and unmute in their row, and the guest sees a message that the host muted them.
