Audio Test

Audio Test Tool Introduction

This is a professional microphone detection and audio testing tool that helps you:

• Detect whether the left and right microphone channels are working properly
• Test the output effect of different audio signals
• Real-time visualization of audio frequency
• Adjust volume and frequency parameters

Particularly suitable for:

• Computer/mobile external microphone detection
• Headphone left-right channel balance testing
• Audio device calibration
• Audio developers for testing purposes

How to Use Audio Test

Select the test channel by clicking the single-choice button to choose the channel to test:

• Left Channel: Test only the left microphone
• Right Channel: Test only the right microphone
• Stereo: Test both left and right microphones simultaneously (default)

Select the audio effect type from the dropdown menu to choose the test sound:

• Sine Wave: Pure single-tone sound (frequency adjustable)
• White Noise: Random noise across the full frequency range
• Audio Sample: Stereo test music

Start Test: Click the play button to begin testing.
During playback, the button changes to 'Stop'.
Adjust Parameters: Use the slider to adjust volume level (range: 0-1).
When selecting Sine Wave:

• Adjustable frequency (10-20000 Hz)
• Can directly input values or use the slider

Observe Visualization: The frequency graphs on the left and right sides display in real time:

• Blue: Left channel frequency
• Red: Right channel frequency

Test Complete:

• Click 'Stop Playback' to end the test
• Switch between different settings for multi-dimensional testing

Tool Usage Tips

• When testing headphones, it is recommended to first select a single channel to confirm correct left/right earpiece placement.
• White noise is suitable for testing the full-frequency response of microphones.
• Sine wave is ideal for testing sound emission at specific frequencies.
• It is recommended to gradually increase volume starting from 0.3 to avoid sudden loud sounds.
