How to fix echo or feedback on Zoom and video calls
August 19, 2026
Echo on a video call is almost always audio feedback, not room reverb — your speaker plays the other person's voice, your microphone picks it back up, and sends it right back to them in a loop. That's a live, in-the-moment problem, and the fix is headphones and call settings, not a post-processing tool. Here's how to tell which problem you actually have, and what fixes each one.
Feedback vs. room reverb: two different problems
Feedback is a loop: your speaker plays sound, your mic hears it, and sends it back — heard as your own voice or the other person's repeating back at them. It only happens live, during the call, and it stops the instant the loop breaks (someone mutes, or switches to headphones).
Room reverb is different: it's reflected sound baked into one person's recording from a hard-walled room, present constantly — on a call or off. This is the same problem covered in our room-echo removal post — a post-processing fix works for this, but not for live feedback.
Quick test: if the "echo" stops the moment you or the other person mutes or puts on headphones, it's feedback. If it's a constant hollow quality present the whole time regardless of muting, it's room reverb.
Fixing feedback during a live call
Use headphones instead of speakers. This is the single most effective fix — it breaks the loop by keeping the call audio out of the room your microphone can hear, entirely.
Mute when not speaking. A muted mic can't feed the loop, even if your speaker is still playing.
Check for duplicate devices in the same room. A phone and laptop both joined to the same call, in the same room, is one of the most common causes — each device's speaker feeds the other's microphone.
Lower your speaker volume if headphones genuinely aren't an option — quieter speaker output gives your mic less to pick back up.
Zoom's built-in echo settings
Zoom has audio settings specifically for this: noise and echo suppression toggles, and an "Original Sound" option that can interact with (and sometimes disable) that suppression. Checking these settings before an important call is worth the thirty seconds — most feedback complaints on Zoom specifically trace back to Original Sound being enabled without realizing it turns off the built-in echo cancellation.
Can you fix feedback after the call is already recorded?
Honestly — not well. Feedback is a duplicate, looped copy of audio mixed into the original in a way that's hard to cleanly separate after the fact, unlike room reverb, which is a more consistent, characterizable kind of distortion that de-reverb tools are built to target. If a call recording has genuine feedback throughout, prevention (headphones, single device) is the real fix — there isn't a reliable undo.
If what you're actually hearing on the recording is a constant hollow quality rather than a looping repeat, that's room reverb, not feedback — and that is fixable after the fact. Try WavyVid's echo removal tool free on the recording to check.
The bottom line
Live call echo is almost always feedback — fix it with headphones and muting, not software. If your recorded call sounds hollow rather than looped, that's a different problem (room reverb) with a real software fix: clean it up here, free and in your browser.
Frequently asked questions
What causes echo on a video call?
Most call echo is audio feedback: your speaker plays the other person's voice, your microphone picks it back up, and sends it back to them — creating a loop. This is different from room reverb, which is reflected sound baked into a single person's recording.
How do I stop echo during a live Zoom call?
Use headphones instead of speakers (removes the mic-speaker loop entirely), mute when not speaking, and check that only one device per person is connected to the call — a phone and laptop both joined in the same room is a common feedback cause.
I already recorded the call — can I fix the echo afterward?
If the echo is feedback (a looped repeat of someone's voice), it's hard to fully separate from the wanted audio after the fact. If what you're actually hearing is room reverb on one person's mic, that's fixable in post the same way as any other room-echo recording.
Does Zoom have a built-in setting for this?
Yes — Zoom's audio settings include noise and echo suppression options (and "Original Sound" toggles that can interact with them). Checking these before a call prevents the problem rather than needing a fix afterward.
How do I know if it's feedback or room echo?
Feedback sounds like your own voice or the other person's voice repeating back, tied to the live loop — it usually stops the moment someone mutes or puts on headphones. Room echo is a constant hollow, distant quality present on the whole recording, on or off a call.
