Mic Test

• Instant confidence – Know your microphone works before joining meetings, starting streams, or recording content.
• Catch issues early – Discover muted mics, wrong device selections, or low volume before they cause problems.
• Visual confirmation – Real-time audio bars show you exactly when your mic is picking up sound.
• Test any microphone – USB mics, headsets, wireless earbuds, webcam mics, laptop built-in mics, and professional audio setups.
• Complete privacy – All audio processing happens locally in your browser; nothing is recorded or transmitted.
• Recording feature – Optionally record and playback audio to hear how you actually sound.

1. Click "Check Microphone" – The button above starts the mic test process.
2. Grant permission – When your browser asks for microphone access, click "Allow" to continue.
3. Select your microphone – If you have multiple audio inputs, choose the one you want to test from the dropdown.
4. Speak into your microphone – Talk at normal volume, like you would on a call.
5. Watch the visualizer respond – Green bars moving indicate your mic is successfully capturing audio.
6. Check the volume percentage – Aim for 40-70% for clear audio without clipping.
7. Try the record feature – Record a short clip and play it back to evaluate your sound quality.

Before running our online mic test, verify Windows audio settings. Right-click the speaker icon in your taskbar and select "Sound settings" or "Open Sound settings." Under Input, confirm your preferred microphone is selected. Speak and watch the input level bar—if it moves, Windows sees your mic.

If your mic isn't detected, check privacy settings. Go to Settings > Privacy & Security > Microphone (Windows 11) or Settings > Privacy > Microphone (Windows 10). Enable "Microphone access" and "Let apps access your microphone." Ensure your browser (Chrome, Firefox, Edge) is allowed. For USB microphones not showing up, try different USB ports or update drivers via Device Manager.

Mac users should verify settings in System Preferences > Sound > Input. Select your microphone and speak—the input level should respond. If nothing happens, macOS may not recognize your device.

Browser permissions matter on Mac. When you click our mic test button, Safari or Chrome will ask for microphone access—click Allow. If previously denied, go to System Preferences > Security & Privacy > Privacy > Microphone and enable your browser. On macOS Ventura or later, this is System Settings > Privacy & Security > Microphone. After enabling, restart your browser and test again.

Our mic test works great on smartphones and tablets. Android users should use Chrome browser—navigate here, tap "Check Microphone," and allow access when prompted. The visualizer will respond to your voice.

iPhone and iPad users get optimal results with Safari. Tap the test button and grant microphone permission. If issues persist, check Settings > Safari > Microphone to ensure it's enabled. Chrome on iOS also works—verify permissions in Settings > Chrome > Microphone.

External microphones work too. Connect your USB-C microphone, Lightning adapter, or Bluetooth headset, then run our mic test. Your phone will route audio through the external device automatically.

Our mic test verifies your hardware works—if it passes here, your microphone will function in all applications. Each app has additional settings worth knowing:

Zoom: After passing our test, go to Zoom Settings > Audio. Select your microphone and click "Test Mic" to hear yourself. Configure noise suppression preferences here too.

Microsoft Teams: Verify in Settings (click profile picture) > Devices. Select your mic and test within Teams. Teams automatically picks your system default.

Discord: Perfect for gamers—test here before voice chat. In Discord, User Settings > Voice & Video lets you select input device and adjust sensitivity thresholds.

Google Meet: Uses browser permissions. If our mic test works, Meet will work. Check Settings (three dots menu) > Audio during a call.

Skype: Settings > Audio & Video shows microphone options. Skype has a test call feature to hear yourself.

• Built-in laptop microphones – Usually above the screen or near the hinge. Convenient but prone to picking up keyboard and fan noise.
• USB microphones – Blue Yeti, Audio-Technica AT2020USB+, Rode NT-USB, Samson Q2U, Elgato Wave. Superior quality for content creation.
• Gaming headsets – HyperX Cloud II, SteelSeries Arctis 7, Razer BlackShark V2, Logitech G Pro X. Great clarity for team communication.
• Bluetooth headphones/earbuds – Apple AirPods, AirPods Pro, Sony WH-1000XM5, Samsung Galaxy Buds, Jabra Elite. Wireless convenience with mic capabilities.
• Webcam microphones – Logitech C920, C922, StreamCam, Razer Kiyo. Decent quality for casual video calls.
• XLR microphones – Shure SM7B, Rode PodMic, Audio-Technica AT2035 via audio interface (Focusrite Scarlett, etc.). Professional broadcast quality.
• Lavalier microphones – Rode Wireless Go, DJI Mic, Hollyland Lark. Clip-on mics for video production.
• Condenser microphones – Studio-grade mics for podcasting, voiceovers, and music production.

• Position your microphone 6-12 inches from your mouth for optimal clarity without excessive breath noise.
• Use a pop filter with condenser mics to eliminate plosive sounds (hard "p," "b," "t" sounds).
• Test in your typical calling environment to account for background noise and room acoustics.
• Keep noise sources minimal—close windows, turn off fans when possible during important calls.
• Basic acoustic treatment helps—blankets, curtains, or even recording in a closet reduces echo.
• Clean your microphone periodically—headset mics especially collect oils and debris.
• Use a boom arm or desk stand to isolate your mic from desk vibrations.
• Enable noise suppression features in Zoom, Teams, or Discord for cleaner real-world audio.

• Before important calls – Job interviews, client meetings, investor pitches, performance reviews.
• After connecting new hardware – New microphone, headset, audio interface, or cables.
• When changing audio setup – Switching from headphones to speakers, docking/undocking laptop.
• After system updates – Windows and macOS updates can reset audio settings and permissions.
• When troubleshooting – Someone says "I can't hear you"? Test here first before blaming the app.
• Before recording – Podcasts, YouTube videos, voiceovers, music—always test before hitting record.
• Pre-game preparation – Competitive gaming sessions, streaming, team coordination.
• Before virtual events – Webinars, online classes, virtual presentations.

Our mic test uses the Web Audio API, a native browser technology for real-time audio processing. When you click the test button, the MediaDevices API requests microphone permission. Once granted, your audio stream connects to an AnalyserNode that extracts frequency and volume data. We visualize this data as animated bars, giving you immediate feedback about your microphone's functionality.

The crucial point: everything happens locally in your browser. Your audio never travels to any server. We don't have backend systems receiving microphone data—it's entirely client-side JavaScript. This architecture guarantees complete privacy while providing accurate, real-time mic testing. When you close this page, all audio processing stops instantly. No data to delete because no data was ever collected.
