Online Microphone Test — Audio Spectrum Analysis, Decibel Meter & Recording

Our interactive microphone testing suite enables comprehensive evaluation of any audio input device (built-in laptop microphone, USB studio condenser, Bluetooth headset, or lavalier mic) directly in your browser powered by Web Audio API and MediaDevices API.

Microphone Diagnostic Features

This web-based workbench provides an exhaustive suite of diagnostic utilities to verify and calibrate audio capture:

Live Waveform Visualizer (Oscilloscope): real-time visual representation of sound waves to detect static noise, clipping, audio dropouts, or hum.
32-Band FFT Spectrum Analyzer: graphical breakdown of sound frequencies across low, mid, and high bands to evaluate voice clarity and frequency response.
Peak Decibel Meter (dBFS): accurate amplitude metering from -60 dBFS to 0 dBFS to prevent digital clipping and audio distortion.
Software Gain Slider: adjust input amplification dynamically from 0% to 300% to boost quiet microphones.
Unlimited Voice Recording & Download: capture voice samples with instant playback and web-standard WebM/WAV file downloads.
Hardware Metadata Extraction: inspect native sample rate (44.1 kHz, 48 kHz, 96 kHz), channel configuration (Mono / Stereo), and buffer latency.

When to Test Your Microphone

Run this diagnostic before important online meetings, streaming sessions, or remote calls in applications like:

Video Conferencing & Chat: Zoom, Google Meet, Microsoft Teams, Discord, Skype, Telegram, Slack.
Game Chat & Live Streaming: OBS Studio, Streamlabs, Twitch, TeamSpeak, Counter-Strike 2, Valorant.

Troubleshooting Microphone Issues

If your microphone level stays at 0% or shows a permission error, follow these troubleshooting steps:

Browser Permissions: Click the pad lock icon near the URL bar in your browser and ensure Microphone permissions are set to "Allow".
OS Privacy Settings: In Windows 10/11, navigate to Settings -> Privacy -> Microphone and enable "Allow apps to access your microphone". On macOS, check System Settings -> Privacy & Security -> Microphone.
Hardware Mute Switch: Ensure the physical mute toggle button on your headset or USB microphone cable is turned ON.
Exclusive Access Conflicts: Close background apps (Discord, Skype, Zoom) that might lock audio hardware exclusively.
