Detailed Testing Instructions
1. Browser Compatibility
TestMic.Online works on all modern browsers including Chrome, Firefox, Edge, and Safari. For best results, use the latest browser version and ensure JavaScript is enabled.
2. Granting Microphone Permission
When you click 'Start Test', your browser will ask for microphone access. Click 'Allow' or 'Permit'. This permission only applies to TestMic.Online and can be revoked anytime from your browser settings.
3. Selecting the Right Device
If you have multiple microphones (built-in, USB, headset), use the device selector to choose the one you want to test. Common devices include laptop built-in mics, external USB microphones, and wireless headsets.
4. Understanding Audio Metrics
Volume shows your microphone input level (aim for 70-90%). Clarity indicates audio quality (higher is better). Background Noise measures ambient sound (lower is better). Latency shows processing delay (under 50ms is excellent).
5. Recording and Playback
Use the recording feature to hear how you sound to others. Click 'Start Recording', speak for a few seconds, then 'Stop Recording'. Play back the audio to check for issues like echo, static, or distortion.
Common Issues and Solutions
⚠️ No Sound Detected
Check if your microphone is properly connected. Verify volume isn't muted in system settings. Try selecting a different device from the dropdown. Restart your browser.
⚠️ Permission Denied
Click the lock icon in your browser's address bar. Find microphone permissions and set to 'Allow'. Refresh the page and try again.
⚠️ Poor Audio Quality
Position microphone 15-30cm from your mouth. Reduce background noise by testing in a quiet room. Use headphones to prevent echo. Clean the microphone mesh if it's dusty.
⚠️ High Latency
Close unnecessary browser tabs and applications. Check if your device is under heavy load. Use a wired connection instead of Bluetooth when possible. Update your audio drivers.
