Our microphone quality test provides several key metrics that help you understand your audio setup:
Decibel (dB) Readings: The volume meter shows your audio levels in decibels. For best results, your speaking voice should register between -20 dB and -10 dB. Levels consistently below -30 dB indicate your microphone is too quiet, while levels above -5 dB mean you're speaking too loudly or your mic gain is set too high.
The live waveform display shows the actual shape of your audio signal in real-time. A healthy microphone signal should show clear, consistent waves when you speak. If you see flat lines when speaking, your microphone isn't working. Erratic, spiky patterns might indicate interference or a faulty connection.
The frequency analyzer displays which audio frequencies your microphone is capturing. A good quality microphone should capture a wide range of frequencies. The human voice typically ranges from 85 Hz to 255 Hz for fundamental frequencies, with harmonics extending much higher. If your spectrum looks incomplete or has gaps, it might indicate microphone limitations or audio driver issues.
Our microphone troubleshooting tool can help identify these common issues:
If the waveform stays flat, check if your microphone is muted, properly connected, or selected as the default recording device in your system settings.
Consistently low audio levels mean you need to increase your microphone gain or speak closer to the mic. Check your system sound settings and microphone boost options.
If levels constantly hit maximum, your microphone gain is too high. Reduce the input volume in your system settings to prevent distortion.
Erratic patterns or constant background noise indicate interference. Try moving away from electronic devices or using a different USB port.
Significant delay between speaking and seeing the waveform suggests driver issues. Update your audio drivers or check your audio interface settings.
Wildly fluctuating audio levels might indicate a loose connection, damaged cable, or faulty microphone that needs replacement.
Our online microphone checker is trusted by professionals for:
Our universal microphone test tool works with all types of audio input devices:
Sample Rate Testing: Our tool displays your audio interface's sample rate, typically 44.1 kHz (CD quality) or 48 kHz (professional standard). Higher sample rates capture more audio detail but require more processing power.
Latency Measurement: We measure the delay between audio input and processing. Low latency (under 20ms) is crucial for real-time monitoring. Higher latency can cause echo or sync issues in video calls.
Dynamic Range: The difference between the quietest and loudest sounds your microphone can capture without distortion. Professional microphones typically offer 100+ dB of dynamic range.
If our mic test shows no activity, try these solutions:
This web-based microphone test works in all modern browsers including:
Your privacy is our top priority. All microphone testing happens entirely within your browser - we never record, store, or transmit your audio data. Your microphone input is processed locally on your device and never leaves your computer. This ensures complete privacy while testing your audio equipment.
Frequency Response: This indicates which audio frequencies your microphone can accurately capture. Most voice microphones work best in the 80 Hz to 15 kHz range. Our frequency analyzer helps you visualize your mic's actual frequency response.
Sensitivity: Measures how much electrical output your microphone produces from a given sound pressure level. More sensitive microphones pick up quieter sounds but may also capture more background noise.
Signal-to-Noise Ratio (SNR): The difference between your actual audio signal and background noise. A higher SNR (above 70 dB) means cleaner, more professional audio quality.
Q: How often should I test my microphone?
A: Test your microphone before important calls or recordings, after system updates, when connecting new equipment, or whenever you suspect audio quality issues.
Q: Is this microphone test accurate?
A: Yes! Our test uses professional-grade Web Audio API technology that provides accurate real-time measurements of your microphone's performance.
Q: Can I test multiple microphones?
A: Absolutely! Use the device selector dropdown to switch between all available microphones connected to your computer and test each one individually.
Q: Why is my microphone volume too low?
A: Low volume usually means your microphone gain needs adjustment. Check your system sound settings and increase the microphone input volume or enable microphone boost.
Q: What should the audio levels be for recording?
A: For optimal quality, aim for peak levels between -12 dB and -6 dB. This provides enough headroom to avoid clipping while maintaining good signal strength.
Q: Does this work on mobile devices?
A: Yes! Our microphone test works on smartphones and tablets running iOS or Android with modern browsers like Chrome, Safari, or Firefox.
Q: Can this test detect a broken microphone?
A: Yes, if your microphone shows no activity, erratic patterns, or extremely low levels across all tests, it may indicate hardware failure or connection issues.
Q: Why do I need to allow microphone access?
A: Browser security requires explicit permission to access your microphone. This protects your privacy by preventing websites from recording without consent.
Our professional mic checker includes advanced features for power users:
Use our test to compare different microphones side-by-side. Professional studio microphones typically show consistent, full-range frequency response with low noise floors. Budget microphones may show limited frequency range or higher background noise. Gaming headsets often emphasize mid-range frequencies optimized for voice chat.
For Video Calls: Your microphone should show clear, consistent audio levels without excessive background noise. Test in your actual meeting environment for realistic results.
For Music Recording: Look for wide frequency response and low latency. Professional recording requires clean signals across the full audio spectrum visible in our analyzer.
For Streaming: Ensure consistent audio levels and minimal background noise. Streamers need reliable, clear audio that maintains quality over long sessions.
For Podcasting: Test for warm, natural voice reproduction. Check that your microphone captures the richness of speech without harsh frequencies or muddiness.
Don't let poor audio quality ruin your important calls, recordings, or streams. Our free online microphone test provides instant, professional-grade analysis of your audio setup. Whether you're troubleshooting problems or optimizing your configuration, this comprehensive testing tool gives you all the information you need in seconds.
