This tool helps you comprehensively test microphone performance, including: Real-time volume detection, waveform analysis, spectrum analysis, noise measurement, latency test. Supports all types of microphones, including USB microphones, 3.5mm interface microphones, Bluetooth microphones, laptop built-in microphones, etc.
📖 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 display of microphone input volume, including RMS value, peak level, and current volume percentage. Helps you determine if microphone sensitivity is normal.
Real-time audio waveform graph, visually displaying amplitude changes of sound signals. Helps identify clipping distortion, silent segments, or abnormal noise.
Real-time FFT spectrum analysis, displaying energy distribution of sound across different frequencies. Helps identify resonant frequencies, noise types, and sound quality issues.
Accurately measure latency from microphone input to playback output. Crucial for recording, live streaming, and real-time communication applications.
Measure microphone's minimum noise floor and signal-to-noise ratio, quantitatively evaluating microphone noise performance. Identify buzzing, environmental noise, etc.
Supports all types of audio input devices, automatically detects available microphones in the system. One-click switching between different microphones.
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.
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.
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.
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.
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.
