Microphone Test Online — Quality Checkup & SNR Analysis

A browser-based microphone tester that checks if your mic is working correctly. Shows real-time audio levels, waveform visualization, and device information — no download needed.

How It Works

1

Select your microphone and grant access.

2

We run quick tests: signal, background noise, voice capture, sharp sounds, and latency — each stage starts when you're ready.

3

Get a clear verdict, per-parameter diagnostics, and recommendations.

Test your microphone online — check quality, latency, noise level, and frequency response

We will check:

  • Is the microphone working?
  • Background noise level
  • Voice capture quality
  • Dynamic range
  • Latency
Mode — live visualization and recording you can play back.

What We Measure

5-stage diagnostic: noise, SNR, latency
Signal detection, noise floor, voice capture, dynamic range and round-trip latency measured in one run.
A clear verdict instead of an abstract grade
Ready / usable with caveats / problem — based on stable metrics (signal-to-noise, frequency range, overload), not absolute loudness that drifts with gain.
Noise type classification and fixes
Pinpoints 50/60 Hz hum, preamp hiss, low-frequency rumble or room ambience and tells you how to remove each.
Compare two mics side by side
Run a second test and see Microphone A vs B head to head to pick the better one on noise, SNR and dynamic range.

Frequently Asked Questions

Is this test accurate?

It uses the Web Audio API for precise measurement within browser capabilities. While not a replacement for professional calibrated equipment, it provides reliable comparative results and identifies real problems.

What is a good SNR?

Above 40 dB is good for most purposes. Above 50 dB is excellent. Below 30 dB means background noise will be clearly audible.

Why does my mic have electrical hum?

Usually caused by poor USB grounding, proximity to monitors/power supplies, or low-quality cables. Try a different USB port or use a powered USB hub. For detailed diagnosis, run our microphone noise test.

Can I compare two microphones?

Yes! After the first test, click "Compare with Another Mic" to run a second test and see a side-by-side comparison.

What browsers are supported?

Chrome, Edge, Firefox, and Safari (14+). We recommend Chrome or Edge for the best accuracy.
