Online Mic Test & Microphone Playback
Run a mic test online to measure input level, background noise, peak signal, clipping, and estimated latency in real time. Use the recorder and playback option to hear yourself on a laptop, desktop, Android device, or iPhone. 100% private — zero audio is stored or uploaded.
Live Microphone Diagnostic Lab
Automatically calibrate background noise, then watch real-time input volume, peak, clipping, and voice replay.
How to test your microphone online in 3 steps
- Allow browser microphone access: Click the "Test Microphone" button and select "Allow" when your browser prompts for microphone permissions.
- Speak at your natural volume: Talk in your normal voice as if you are on a call or in a meeting. Watch the live RMS volume meter move into the green zone.
- Review live metrics and replay your voice: Confirm that your speech sits between −30 and −12 dBFS without clipping, and use Hear Yourself to record a quick sample and listen back.
Mic test recorder and playback
Start the live mic test, allow browser permission, and speak at the volume you normally use on a call. The meter should respond immediately. For a mic test with playback, open Hear Yourself and record a short sample. Listening back can reveal static, muffling, distortion, or the wrong input device more clearly than a moving meter. Recordings stay in temporary browser memory and are not uploaded.
What this test measures
- RMS Level
- Root-mean-square average of your microphone input. A healthy voice recording typically sits between −30 and −12 dBFS.
- Peak dBFS
- The loudest sample in each analysis frame. Sustained peaks near 0 dBFS indicate clipping — digital distortion that cannot be corrected in post.
- Noise Floor
- RMS level measured during silence. A quiet environment is below −55 dBFS. Higher readings indicate background noise, fan hum, or electrical interference.
- Estimated Latency
- Reported only if your browser exposes
AudioContext.baseLatencyoroutputLatency. Labeled “estimated” because browser-reported values are approximate.
How to interpret your result
| Metric | Good range | Needs attention |
|---|---|---|
| RMS Level | −30 to −12 dBFS while speaking | Below −40 (too quiet) or above −6 (too loud) |
| Peak | Below −3 dBFS | At or near 0 dBFS — clipping detected |
| Noise Floor | Below −55 dBFS (quiet) | Above −40 dBFS (loud environment) |
How to test and fix your mic on Windows, Mac, and iPhone
Windows 11 / 10
Go to Settings > System > Sound. Under Input, select your microphone and verify the volume slider is at 80–100%. If the meter does not move, check Privacy & security > Microphone to ensure apps and browsers have microphone access enabled.
macOS (MacBook & Mac mini)
Open System Settings > Sound > Input. Select your external or built-in microphone and adjust the input slider. If the browser shows permission denied, open Privacy & Security > Microphone and toggle your browser on.
iPhone & iPad (Safari)
When Safari prompts for microphone access, tap Allow. If you previously tapped Block, tap the aA icon in the Safari address bar > Website Settings > Microphone > set to Allow.
Discord, Zoom & Teams
If your mic works here but fails in calls, open the app's audio settings and change the input device from "Default" to your specific microphone model. In Discord, turn off "Automatically determine input sensitivity" if your voice cuts out.
Troubleshooting next steps
- No signal detected: Check that your microphone is plugged in and selected as the input device in your OS settings.
- Signal too quiet: Increase your microphone gain in system settings. Check our Fix Low Microphone Volume Guide.
- Clipping consistently: Lower your microphone gain or move further from the microphone. Run the clipping test.
- High noise floor: Move to a quieter room, disable laptop fans where possible, or check our Fix Mic Background Noise Guide.
Quick answers
Frequently asked questions
How can I test my mic?
Open the mic test, allow microphone access, select the input you want to check, and speak at your normal call volume. Watch the live level for a steady response, try a louder phrase to check for clipping, and record a short sample so you can listen for noise, muffling, or dropouts.
What is a mic test used for?
A mic test confirms that your browser is receiving the correct microphone and helps you check input level, background noise, clipping, latency, and voice clarity before a call, stream, class, interview, or recording.
Is an online mic test safe?
It can be safe when you use a trusted HTTPS website and review the browser permission prompt. AudioSolver processes microphone audio in your browser; it does not upload your recording. Temporary recordings are cleared when you reload or leave the page, and you can revoke microphone permission in your browser settings.
Can I test my mic online?
Yes. A browser-based online mic test works without installing software on most laptops, desktops, Android phones, and iPhones. Your browser must support microphone access, and you must grant permission before the live meter or recorder can receive audio.
How do I use a microphone correctly?
Keep the microphone in a stable position and speak across it rather than directly into it. For a typical voice mic, start about 10–20 cm (4–8 inches) away, keep your distance consistent, and use a pop filter if plosive sounds are strong. The best position varies by microphone and room.
How do I get the best microphone settings?
There is no single perfect setting for every microphone. Select the correct input, disable effects you do not need, reduce room noise, and adjust gain so normal speech is clear while louder words remain below 0 dBFS. Peaks around −12 to −6 dBFS are a useful starting point for many voice recordings.
How can I tell whether my microphone is good?
A good result sounds clear and natural, has a stable level, low background noise, no digital clipping, and no random dropouts. Listen to a short recording and compare it with another cable, port, browser, or device if you hear a problem; that helps separate microphone faults from connection or software issues.
How do I test a microphone on my phone?
Open the mic test in your phone browser, allow microphone access, and speak toward the microphone opening you want to check. Disconnect Bluetooth devices if you mean to test the built-in phone mic. Mobile operating systems may choose the active input automatically, so repeat the test after changing accessories.
