Professional Microphone Test Tool Features

📖 Introduction: Professional microphone test tool provides comprehensive audio detection features, from basic volume testing to advanced spectrum analysis, helping you fully understand microphone status. Supports all types of microphones, including USB microphones, 3.5mm interface microphones, laptop built-in microphones, etc.

🔍 Real-time Volume Detection

Real-time display of microphone input volume, including RMS value, peak level, and current volume percentage. Helps you determine if microphone sensitivity is normal.

Tip: Normal speech should be between -20dB and -6dB

⚡ Waveform Analysis

Real-time audio waveform graph, visually displaying amplitude changes of sound signals. Helps identify clipping distortion, silent segments, or abnormal noise.

⏱️ Spectrum Analysis

Real-time FFT spectrum analysis, displaying energy distribution of sound across different frequencies. Helps identify resonant frequencies, noise types, and sound quality issues.

Monitor spectrum graph to identify abnormal frequency peaks

🔧 Latency Test

Accurately measure latency from microphone input to playback output. Crucial for recording, live streaming, and real-time communication applications.

Professional audio interfaces typically have less than 10ms latency

🎯 Noise Measurement

Measure microphone's minimum noise floor and signal-to-noise ratio, quantitatively evaluating microphone noise performance. Identify buzzing, environmental noise, etc.

High-quality microphones should have SNR greater than 70dB

📊 Multi-device Support

Supports all types of audio input devices, automatically detects available microphones in the system. One-click switching between different microphones.

Supports USB, 3.5mm, Bluetooth, and other interfaces

Frequently Asked Questions (FAQ)

Why is my microphone not working?

This may be due to browser permissions, system settings, or hardware issues. Please ensure: 1) You've allowed browser access to the microphone; 2) Correct default input device in system settings; 3) Microphone hardware is properly connected. Check audio latency issues using our Audio Latency Test Tool.

How to identify microphone issues?

If your microphone: 1) Shows no waveform at all; 2) Has extremely low volume; 3) Has obvious buzzing or static noise; 4) Has very high latency, it may indicate hardware issues.

What are RMS and Peak?

RMS (Root Mean Square) indicates average volume, while Peak indicates maximum instantaneous volume. Normal speech should have RMS around -20dB, with peaks not exceeding -6dB to avoid clipping.

What types of microphones are supported?

Supports all types of microphones: USB microphones, 3.5mm interface microphones, XLR microphones (requires interface), laptop built-in microphones, Bluetooth microphones, etc. Compatible with Windows, macOS, Linux systems.

How to test microphone latency?

The tool automatically performs latency tests. The system emits test tones and measures round-trip latency from input to output, with results displayed in the "Audio Latency" stats item.

Is test data saved?

All test data is only saved in the current browser session. Data will be lost after refreshing the page or closing the tab. To save results, please use screenshot functionality or manually record data.
