This mic test online checks whether your microphone is capturing audio — select your input device from the mic selector, click Test my mic, speak a few words, and the audio waveform lights up in real time to confirm your mic is picking up sound. Your input volume level shows whether you're coming in too quiet or peaking too loud, while the quality rating and mic info panel surface live readings for sample rate, channels, noise suppression, and echo cancellation pulled directly from your device. If the waveform moves when you talk, your microphone is working; if it stays flat, the status message tells you exactly what's blocking your mic access so you can fix it. The free hearing test online takes under two minutes and runs entirely in your browser.
A microphone that looks connected is not always a microphone that is working. Running a quick mic test online takes under 30 seconds and catches problems before your audience, interviewer, or teammates hear them first.
Pair your microphone test with our tone generator to verify speaker output at the same time.

Choose your input device from the mic selector dropdown. If you only have one microphone connected, it is selected automatically.
Hit Test my mic and click Allow when your browser asks for permission. This is a standard browser security prompt — your voice never leaves your device.
Say a few words. If the audio waveform moves and the input volume bar rises when you speak, your mic is capturing sound correctly.
The Mic Info panel auto-fills with your device name, sample rate, channels, latency, echo cancellation status, and overall quality rating.
After the online microphone test, the Mic Info panel fills automatically with live readings from your browser’s audio API. Every value is a real system reading — not an estimate. Here is what each result means:
An overall score — Excellent, Very Good, Good, Fair, or Poor — based on your mic’s reported capabilities. Good or above means your microphone is ready for calls, recording, and streaming. Fair is passable for casual use. Poor usually points to a very low sample rate or high latency — common with cheap built-in mics or Bluetooth headsets operating in headset mode.
Shows how loud your mic is capturing audio in real time. A healthy level sits in the middle range — not clipping at the top, not flatlined at the bottom. If you are consistently too quiet, increase your microphone input gain in your OS sound settings. Too loud and you risk distortion on calls and recordings.
Measured in Hz — typically 44,100Hz or 48,000Hz. Higher sample rates mean audio is captured with more detail. 44.1kHz is standard for music recording; 48kHz is standard for video calls, podcasting, and broadcast. A very low sample rate like 8,000Hz will limit your audio quality regardless of the physical microphone.
Shows whether your browser is applying software echo cancellation and noise suppression to your mic input. Echo cancellation prevents your speakers from feeding back into your mic during calls. Noise suppression filters steady background sounds — fan hum, air conditioning, keyboard noise — before audio reaches the other person.
Shows whether your mic captures in mono (1 channel) or stereo (2 channels). Most headset and built-in laptop microphones are mono, which is correct for voice calls and recording. Stereo matters mainly for instruments, ambience recording, and ASMR content.
The delay between when you speak and when your microphone captures the audio, in milliseconds. Under 20ms is ideal for live calls and recording. High latency — 50ms or above — causes noticeable delay in monitoring and can make video call audio feel out of sync. For a full round-trip measurement, use the audio latency test tool.
Whether you’re preparing for a call, setting up a studio, or troubleshooting audio, a quick mic test is the fastest way to confirm everything is working before it matters.
Muted by mistake, wrong input selected, or volume too low — these are the top reasons people can’t be heard on Zoom, Google Meet, Microsoft Teams, and Discord. A 30-second microphone test online before you join confirms your mic is live, your input level is right, and your echo cancellation is active — so you are not the person everyone is asking to repeat themselves.
Your teammates can’t hear you mid-game, or your stream audio sounds distorted — these issues come from mic settings that look correct but aren’t. Run your mic test before a session to catch input level, background noise, and latency issues before they affect your content. Check your background noise level and your gaming headset’s sample rate while you are at it.
Before you record a long session, verify your microphone’s sample rate, channel configuration, and input volume match your recording software’s expectations. A sample rate mismatch or clipping input can ruin hours of audio. Running a quick online microphone test before you hit record takes under a minute and saves hours of post-production time.
USB microphones, headsets, and audio interfaces all need browser permission before they work in web apps. The mic test online confirms your new device is detected, recognized by name, and performing at spec — sample rate, latency, and all. If something is wrong, you know immediately rather than mid-call.
The mic test uses standard WebRTC and the browser’s getUserMedia API — it works on any device with a microphone and a modern browser. No plugins, no Flash, no extensions required.
Works on Windows 10/11, macOS, and Linux across Chrome, Firefox, Edge, Safari, and Brave. On Windows, set your mic as the default recording device in Sound Settings. On macOS, grant browser access under System Settings → Privacy → Microphone. Supports USB microphones, built-in mics, and audio interfaces.
The microphone test online works on Android via Chrome and on iPhone and iPad via Safari. On iOS, only Safari supports microphone API access — Chrome and other third-party browsers on iPhone are restricted by Apple from using the mic API, so use Safari for best results.
Plug in your USB microphone, headset, or audio interface before opening the page, then select it from the mic selector dropdown. It appears alongside any built-in microphone. Refresh the page if you connect a new device after the page has already loaded.
The online mic test surfaces the most common microphone issues in seconds — before they cause problems on a call, stream, or recording.
Your browser has not been granted microphone permission, or the wrong input device is selected. Click the mic selector, choose your device, and check your OS has not muted or disabled that input. On Windows: Sound → Recording tab. On macOS: System Settings → Sound → Input.
The audio waveform moves but the level bar barely rises (too quiet) or constantly hits the top (clipping). Adjust your microphone input gain in your OS sound settings. Windows: Recording → Properties → Levels. macOS: Sound → Input → Input Volume slider.
Your mic is capturing audio but the quality rating is Poor or Fair. This usually means a very low sample rate (under 16kHz) or high latency — typical of cheap built-in laptop microphones or Bluetooth headsets operating in headset mode. Try a wired microphone for comparison.
Look for the blocked permissions icon in your browser’s address bar, click it, and set microphone to Allow. Refresh and run the mic test again. If still blocked, check that your OS allows the browser to access the mic — on macOS this is under Privacy & Security → Microphone.
