Our Mission
Professional Audio Testing,
Free for Everyone
We built Mic Test because audio quality matters — and every person, whether in a job interview, podcast, classroom, or client call, deserves a fast, private, and accurate way to verify their microphone works. No paywalls. No accounts. No compromise.
Professional-Grade Diagnostics
Real-time FFT spectrum, waveform oscilloscope, SNR analysis, noise fingerprinting — the same tools used by audio engineers, available free in a browser tab.
Zero-Knowledge Architecture
Every test runs entirely inside your browser. No audio reaches our servers. Ever. Verified in seconds via DevTools → Network tab.
Sub-Second Performance
From page load to live waveform in under one second. Built for performance as a first principle — no loading screens, no interstitial ads.
What We Do
Eight Powerful Tools,
One Simple Page
Every feature runs entirely inside your browser using the Web Audio API. Your audio is never sent to any server — complete privacy, always.
🌊
Real-Time Waveform & Frequency Analyser
See your voice as a live waveform at up to 60 FPS. Spot clipping, dead frequencies, and distortion instantly before any call or recording.
🎧
Live Monitor & Echo Test
Hear yourself live through headphones with near-zero latency. Toggle a 1-second echo delay to evaluate feedback loops in video calls.
⏺️
Record & Playback
Capture audio in-browser, play it back instantly, and download as high-quality WebM. No recording software needed.
🔁
Mic Comparison — A/B Test
Record the same phrase with two different microphones, toggle between playbacks, and hear the difference in warmth, clarity, and noise floor.
🌍
Noise Environment Test
Play background noise and watch sensitivity respond in real time. Toggle Noise Suppression on and off to test your mic in the conditions you'll actually use it.
🛠️
Device Diagnostics & Gain Control
Full technical readout: device name, sample rate, channel count, latency, and audio processing flags. Plus 2× software Gain Boost for quiet microphones.
Our Values
What We Stand For
Six principles that guide every decision we make — from how we build features to how we handle your data.
01 — PRIVACY
Zero-Knowledge Architecture
Your voice never leaves your device. All processing happens in a JavaScript sandbox inside your browser tab and is destroyed the moment you click Stop.
02 — ACCESSIBILITY
Free for Everyone, Always
No paywall. No free trial. No email gate. 100% of all features are available to every visitor immediately, forever, with no strings attached.
03 — PERFORMANCE
Speed as a First Principle
From page load to live waveform in under one second. No loading screens, no interstitial ads. Built fast and kept fast as the product grows.
04 — QUALITY
Professional-Grade, Consumer-Friendly
The same analytical tools used in audio engineering — FFT spectrum, SNR analysis, noise fingerprinting — made accessible to anyone on any device.
05 — TRANSPARENCY
Verify Everything Yourself
Open DevTools → Network tab during any test. You'll see zero audio requests because none are made. We invite scrutiny — we have nothing to hide.
06 — EDUCATION
Knowledge That Empowers
Not just a test button — a complete learning resource. Guides on mic types, noise suppression, phantom power, and troubleshooting every common audio problem.
Privacy Pledge
Your Voice Stays
On Your Device
A commitment we make to every user — verified, transparent, and non-negotiable.
No Server Audio Storage
Zero audio data ever reaches our servers. The microphone stream exists only inside your browser's JavaScript memory — nowhere else.
Zero Audio Transmission
No audio samples, voice clips, or metadata are transmitted to any server or third-party service at any point during or after testing.
0-Second Data Retention
Audio is processed only in the current session and destroyed the moment you close the tab or click Stop. Nothing persists anywhere.
No Account Required
No email address, no registration, no sign-in. We cannot identify you because we collect nothing that would allow us to.
No Audio Analytics
Analytics are limited to standard page-view metrics only. We never analyse, profile, or fingerprint your audio input or voice characteristics.
HTTPS Required
Browser-enforced HTTPS on all pages. The Web Audio API microphone access requires a secure context — protecting your data in transit by default.
Verify our claim yourself in 10 seconds: Open your browser's developer tools (press F12), go to the Network tab, then start the mic test and speak. You will see zero network requests containing audio data — because none are made.
F12 → Network → 0 audio requests
