Phase Delay: ~180msThe 3-Point Acoustic Feedback Loop:
Your laptop or desktop external speakers play caller audio into the physical room air.
The sound wave bounces off walls and re-enters your open microphone capsule delayed.
Wearing headphones eliminates 100% of open speaker loopback instantly.
Live Microphone Audio Signal Check
Verify that your microphone is receiving and streaming audio data directly in your browser.
Measures the acoustic room silence, PC fan hum, and electrical interference when you are not speaking. Stay silent for 3 seconds to measure your baseline noise floor.
Record a 5-second sample to verify voice clarity, playback volume, and background noise.
माइक की समस्या हल करने के आसान उपाय (Troubleshooting Steps)
यदि आपका माइक काम नहीं कर रहा, आवाज़ धीमी है या गूंज रही है:
Hardware Mute Switch Check
Inspect your headset cable or earphone inline control for a physical mute toggle or volume wheel turned down.
अपने ईयरफ़ोन या हेडसेट के तार पर देखें कि कोई फिजिकल म्यूट (Mute) बटन तो ऑन नहीं है या वॉल्यूम व्हील कम तो नहीं है।
Browser Permission Unlock
Click the lock or tune icon next to the website address in Chrome or Safari, switch Microphone to "Allow", and reload.
वेबसाइट के लिंक (URL) के पास बने लॉक (🔒) आइकन पर क्लिक करें और Microphone को “Allow” करके पेज रीफ़्रेश करें।
System Input Gain Adjustment
Open Windows Settings → Sound or macOS System Settings → Sound → Input and set the input level slider to 85%–90%.
Windows की Sound Settings या Mac की Sound Input Settings में जाकर माइक्रोफ़ोन वॉल्यूम को 85% से 90% पर सेट करें।

Echo is almost never caused by the person who hears it. If caller A hears their own voice repeating, the issue is on caller B’s computer: caller B’s speakers are playing caller A’s voice into caller B’s open microphone.
Frequently Asked Questions
Q.What is the fastest way to fix an echo in a meeting?
Put on headphones. When speaker audio is piped directly into your ears instead of into the room air, the microphone physically cannot pick it up.
Q.What is Acoustic Echo Cancellation (AEC)?
AEC is a DSP algorithm used by WebRTC, Zoom, and Google Meet to digitally subtract known speaker output from incoming microphone signals.
