1. Click the "Check Microphone" button – Located above, this initiates the microphone test sequence.

3. Select your microphone – If you have multiple audio input devices, choose the one you want to test from the dropdown menu.
4. Speak into your microphone – Talk at your normal speaking volume, as you would during a call.
5. Watch the audio visualizer – Moving green bars indicate your microphone is successfully capturing audio.
6. Check the volume level – The percentage indicator shows your current input level. Aim for 50-80% for optimal clarity.
7. Test with recording (optional) – Click "Record" to capture a short clip, then play it back to evaluate your actual audio quality.

Before using our online mic check tool, ensure Windows is configured correctly. Right-click the speaker icon in your taskbar and select "Sound settings" (Windows 11) or "Open Sound settings" (Windows 10). Under the Input section, verify your preferred microphone is selected from the dropdown. Speak and watch the volume bar move to confirm Windows detects your mic properly.

If your microphone isn't being detected, open Settings > Privacy & Security > Microphone (Windows 11) or Settings > Privacy > Microphone (Windows 10). Ensure "Microphone access" is turned on and "Let apps access your microphone" is enabled. Also verify that your browser (Chrome, Firefox, or Edge) appears in the list of allowed apps. For USB microphones, try disconnecting and reconnecting to a different USB port, or check Device Manager for driver issues.

On macOS, configure your microphone through System Preferences (or System Settings on macOS Ventura and later). Navigate to Sound > Input and select your microphone from the device list. Speak and watch the input level meter respond—if the bars move, macOS is receiving audio from your mic.

When you click "Check Microphone" on our site, Safari or Chrome will request microphone permission. Click "Allow" to grant access. If you previously denied permission, go to System Preferences > Security & Privacy > Privacy > Microphone and check the box next to your browser. On macOS Ventura+, this is under System Settings > Privacy & Security > Microphone. After enabling, refresh this page and try again.

Our mic check tool works seamlessly on smartphones and tablets. On Android devices, open Chrome browser and navigate to this page. Tap "Check Microphone" and select "Allow" when prompted for microphone access. If you don't see the permission prompt, go to Chrome Settings > Site Settings > Microphone and ensure it's set to "Ask first" or allowed for this site.

On iPhone and iPad, Safari provides the best experience. Open this page in Safari, tap the test button, and allow microphone access when prompted. If the mic doesn't respond, check Settings > Safari > Microphone and ensure it's enabled. For Chrome on iOS, go to Settings > Chrome > Microphone.

Testing external microphones on mobile is straightforward—simply connect your USB-C or Lightning microphone, or pair your Bluetooth headset. Your phone will automatically route audio through the external device. Run our mic check to verify it's working before your call.

Our mic check tool is perfect for pre-call testing because it verifies your actual hardware works. If your microphone passes our test, it will function in any application—the issue would be app-specific settings, not your mic.

Zoom: After confirming your mic works here, open Zoom Settings > Audio. Select your microphone from the dropdown and click "Test Mic" to double-check. Zoom also offers background noise suppression settings worth configuring.

Microsoft Teams: Teams uses your system's default microphone. Test here first, then verify in Teams by clicking your profile > Settings > Devices. You can test directly within Teams by starting a test call.

Discord: For gamers, our mic check before joining voice channels prevents the "can you hear me?" dance. In Discord, go to User Settings > Voice & Video to select your input device and adjust input sensitivity.

Google Meet: Meet relies on browser permissions—if it works here, it works in Meet. Click the three dots in a Meet call > Settings > Audio to verify device selection.

Skype: After our mic check, verify in Skype via Settings > Audio & Video. Skype offers a test call feature to hear how you sound.

• Built-in laptop microphones – The small mic above your screen or embedded in your laptop's body. Convenient but often picks up keyboard noise.
• USB microphones – Popular choices like Blue Yeti, Audio-Technica AT2020USB+, Samson Q2U, and Rode NT-USB. These offer superior quality for podcasting and streaming.
• Gaming headset microphones – Headsets from HyperX, SteelSeries, Razer, and Logitech with attached boom mics. Great for clear voice chat.
• Webcam microphones – Many webcams like Logitech C920, C922, and Razer Kiyo include built-in mics. Decent for casual calls.
• Bluetooth headphones – Apple AirPods, AirPods Pro, Sony WH-1000XM4/XM5, Bose QuietComfort, and other wireless earbuds with integrated mics.
• XLR microphones – Professional condenser mics like Shure SM7B or Audio-Technica AT2035 connected through an audio interface (Focusrite Scarlett, etc.).
• Lavalier/lapel microphones – Small clip-on mics popular for video recording and presentations. Often connect via 3.5mm or USB.
• Condenser microphones – Studio-quality mics for professional podcasting, voiceovers, and music recording.

• Position your microphone 6-12 inches from your mouth for optimal clarity and minimal background noise pickup.
• Use a pop filter or windscreen to eliminate plosive sounds and breath noise that cause audio spikes.
• Test in your actual calling environment—background noise, echo, and room acoustics all affect quality.
• Close windows and turn off fans or AC units during important calls when possible.
• Consider basic acoustic treatment—even hanging clothes in a closet makes a noticeable difference for echo reduction.
• Clean your microphone regularly, especially headset mics that collect skin oils and debris over time.
• Use a boom arm or desk stand instead of holding your mic to eliminate handling noise and vibrations.
• Enable your application's noise suppression feature—Zoom, Teams, and Discord all have built-in AI noise reduction.

• Before important meetings – Job interviews, client presentations, investor pitches, team standups—always test first.
• After connecting new audio hardware – New headset, USB microphone, audio interface, or even new cables.
• When switching between devices – Moving from headphones to speakers, laptop to external monitor, or docking/undocking.
• After operating system updates – Windows and macOS updates occasionally reset audio settings or permissions.
• When troubleshooting audio issues – If someone says "I can't hear you" or "you're breaking up," verify your mic works here first.
• Before recording sessions – Podcasts, YouTube videos, voiceovers, music—always test before hitting record.
• Before gaming sessions – Ranked competitive matches, streaming to viewers, or coordinating with your squad.
• Before online exams – Many proctored tests require working audio and will fail you for technical issues.

Our mic check tool leverages the Web Audio API, a powerful browser technology that enables real-time audio processing directly in your browser. When you click "Check Microphone," your browser uses the MediaDevices API to request microphone access. Upon approval, we receive a live audio stream from your selected input device. This stream is then processed by the Web Audio API's AnalyserNode, which extracts frequency and amplitude data from your audio signal.

This data is visualized as animated bars on your screen, providing real-time feedback about your microphone's input levels. The entire process happens locally—your audio data never travels over the internet to any server. We have no backend infrastructure receiving or storing audio; it's all client-side JavaScript running in your browser. This architecture ensures complete privacy while delivering accurate, instantaneous feedback about whether your microphone is functioning correctly. When you close the page, all audio processing stops immediately.
