How to Use the Online Echo Test
1
Allow Mic Access & Start
Click "Start Echo Test" and allow microphone permission when prompted. A 3-second countdown begins. Use headphones or lower your speaker volume first — this prevents real-time feedback from reaching your mic during the recording.
2
Speak Naturally During the 3-Second Recording
Say a few words clearly at a normal conversational volume. The tool records exactly 3 seconds of audio. Minimize background noise for the most accurate playback result.
3
Listen to Playback & Report the Result
Your recording plays back automatically. If you hear your own voice again with a noticeable delay or hollow effect, that is echo. Select "Yes, I heard echo" to get targeted troubleshooting tips, or "No, everything sounds normal" to confirm your audio setup is clean.
Common Echo Causes & Fixes
If the echo test detected feedback or a loop, here are the most likely causes and how to fix them:
Speakers feeding back into your mic
Your microphone picks up sound from your speakers, creating an audio loop. Fix: use headphones during calls, or lower your speaker volume significantly before retesting.
Microphone monitoring enabled in OS settings
Your operating system or audio driver may be routing mic input directly to your output. Disable "Listen to this device" in Windows Sound settings, or turn off Input Monitoring on macOS.
Another audio app is holding your mic
Video call apps like Zoom, Teams, or Discord can hold the microphone and apply their own loopback. Close all other audio apps before running the echo test for a clean result.
Room acoustics causing reverb
Hard, bare walls reflect sound back to your microphone. This creates room reverb — not a feedback loop. Soft furnishings, rugs, curtains, and acoustic panels absorb reflections and reduce room echo.
