Microphone Test

Microphone Test Introduction

This is a simple and practical microphone detection tool that helps you quickly test whether your microphone is working properly and displays the audio waveforms of the left and right channels in real time. You can visually observe the audio input to ensure the microphone's sensitivity is functioning correctly. Additionally, this tool supports audio recording functionality: you can record audio and play it back to check the sound quality, and finally download the recorded file for future use or sharing.

Tool Usage Steps

Start Microphone Test
Click the "Start Test" button; your browser will prompt you to grant microphone access permissions. After granting permission, the tool will display the left and right channel audio waveforms in real time. If the microphone is working correctly, you will see the waveform change with sound input.
Test Recording Function (Optional)
After confirming that the microphone test is working properly, click the "Record" button to begin recording audio. During recording, the waveform graph will continue to display the current audio input signal.
Stop Recording and Play Back
After completing the recording, click the "Stop" button to end the recording. The system will automatically generate an audio file and display it in the playback control panel. You can click the play button to listen to the recording result.
Download Recording File (Optional)
If you are satisfied with the recording result, click the "Download" button to save the recording as a WAV-format audio file for future use or sharing.
End Test
After completing the test, click "Stop Test" (the original "Start Test" button will automatically switch) to close microphone access and release system resources.
