Online Speaker Test & Audio Check

Q: How do I perform a left and right speaker test (stereo test)?

Use our "Left/Right Stereo Test" feature. The tool will play a sound exclusively through your left speaker, and then exclusively through your right. This is the best way to confirm that your stereo channels are correctly wired and that both of your speakers are functioning.

Q: How can I test my subwoofer for bass?

The "Low Frequency Test" is designed for this. It plays very low-frequency tones (e.g., 20Hz - 80Hz). You should *feel* these bass tones from your subwoofer more than you *hear* them. If you get no response, check your subwoofer's power, volume, and crossover frequency settings.

Q: What is a speaker frequency sweep?

A frequency sweep plays a continuous tone that glides from the lowest audible frequency (around 20Hz) up to the highest (around 20,000Hz). This is an excellent way to check your speaker's (and your hearing's) overall range and to pinpoint specific frequencies where rattles or distortion occur.

Quickly test your stereo speakers, headphones, and audio system to diagnose common sound problems. No installation is required.

What to Listen For

Each test is designed to help you identify specific audio problems.

Stereo Sound Test

When testing the left or right channel, the sound should come exclusively from that speaker. If you hear sound from both, your stereo channels might be reversed or improperly configured.

Frequency Sweep

Listen for a smooth, continuous tone. Any buzzing, rattling, or crackling could indicate a damaged speaker driver. Gaps in sound might mean your speakers struggle with certain frequencies.

Bass & Treble Tests

The low and high-frequency sounds should be clear and distinct. Distorted, muffled, or "tinny" sounds suggest your speakers cannot reproduce those frequencies accurately at the current volume.

Frequently Asked Questions

I can't hear anything. What should I do?

First, check that your device's volume is not muted or set to zero. Ensure your speakers are properly connected and powered on. If using headphones, make sure they are securely plugged in. Finally, try adjusting the "Test Volume" slider on our tool.

Why does my speaker rattle at certain frequencies?

Rattling or buzzing is often caused by a damaged speaker driver (a "blown speaker"). It can also be caused by a loose component inside the speaker cabinet or something in your room vibrating in sympathy with the sound. Try moving the speaker to see if the rattle persists.

Is this test safe for my speakers and headphones?

Yes, the test tones are standard audio frequencies and are safe for all audio devices when played at a reasonable volume. We strongly recommend starting with a low volume and gradually increasing it to a comfortable level. Do not perform tests at maximum volume for extended periods.
