Mic Echo & Sidetone Test
Hear your own voice exactly as callers do. Test microphone clarity, room reverberation, background hum, and adjust loopback playback delay from 100ms to 2000ms.
How to Use This Tool
- Put on headphones first (this prevents your microphone from picking up your speakers and creating an audio loop).
- Click "Start Echo Test" and allow microphone access in your browser.
- Speak normally into your microphone. You will hear your voice played back in your headphones.
- Use the Echo Delay presets (100ms, 350ms, 500ms) to adjust playback timing, and use the volume slider to set comfortable monitoring levels.
- Click "Stop Echo" when you are done testing.
Why Test with an Echo Delay?
When you speak, you hear your own voice through bone conduction in your skull, which sounds deeper and fuller than how others actually hear you. Playing back your microphone with a 300–500ms delay lets you evaluate how your voice genuinely sounds to teammates on Discord, Zoom, or Teams—revealing any muffled tones, background static, or keyboard clicks.
What Causes Loud Audio Screeching (Feedback)?
Acoustic feedback happens when sound from your speakers travels into your microphone, gets amplified, and loops continuously. This creates an immediate, piercing squeal. Always keep your mic physically away from external speakers or wear headphones during calls.
Microphone Placement Tips
Position your microphone about 5 to 10 cm (2 to 4 inches) away from your mouth, slightly off to the side rather than directly in front of your lips. This prevents forceful breath bursts (plosive "P" and "B" sounds) from slamming into the microphone capsule.
