Left / Right Stereo Speakers Sound Check

This tool uses modern browser audio technology to play test sounds through your speakers. When you click any test button, sound is generated in real time, and the live visualizer confirms that audio is actively playing through your device speakers.

test sound left right

The Left and Right Speaker Test lets you check each speaker individually.
If sound plays from only one side, it clearly indicates a speaker imbalance or hardware issue. This feature is especially useful for diagnosing problems with headphones, mobile phones, and stereo speakers.

Frequency Sweep Test

The Frequency Sweep test plays sound from low bass to high treble frequencies.
It helps identify distortion, missing frequency ranges, rattling, or weak sound output. MySpeakerFixer uses this test to reveal speaker damage that may not be noticeable during normal audio playback.

Phase Test (Speaker Balance Check)

The Phase Test checks whether both speakers are correctly aligned and in sync.
If your speakers are out of phase, sound may feel hollow, weak, or unclear. This test helps detect wiring, polarity, or internal balance issues in stereo systems.

Panning Test (Left to Right Audio Movement)

The Panning Test moves sound smoothly from the left speaker to the right.
This allows you to confirm equal loudness and clarity on both sides, making it ideal for testing Bluetooth speakers, headphones, and home audio systems.

The MySpeakerFixer Advanced Speaker Test Tool makes speaker diagnosis simple, fast, and reliable. Whether you are troubleshooting a phone, laptop, headphones, or external speakers, this tool helps you identify sound issues with confidence.
Test your speakers now and take the first step toward fixing sound problems the smart way.
