Free Sound Test Online: Speakers, Headphones & Audio Check
Test your audio equipment instantly. Check stereo balance, frequency response, bass capability, and phase alignment for speakers and headphones.
Whether you just bought new headphones or you're setting up a home theater, use this comprehensive suite to test your audio equipment.
Essential Audio Tests
1. The Stereo Check (Left/Right)
Verify that your left and right channels are wired correctly.
- Go to Speaker Test
- Why it matters: If your channels are swapped, movies and games will have inverted directional audio (you'll hear footsteps on the left when the enemy is on the right).
2. The Frequency Sweep (20 Hz - 20 kHz)
Play a tone that sweeps from the lowest bass to the highest treble.
- Go to Frequency Sweep
- What to listen for: The sound should remain at a consistent volume. If it gets suddenly quiet or loud at certain pitches, your speakers have "peaks and valleys" in their response.
3. The Subwoofer Test (Bass)
Isolate the low-end frequencies (20-120 Hz) to test your sub.
- Go to Subwoofer Test
- Warning: Start with low volume. Sub-bass vibrations can damage cheap speakers if played too loudly.
4. The Headphone Driver Match
Play a center-panned tone.
- Go to Headphone Test
- The Goal: The sound should appear to come from exactly the center of your head. If it drifts to the left or right, one of your drivers is louder than the other.
Input Tests (Microphone)
Need to check if your mic is working?
- Go to Microphone Test
- Visualize your voice waveform and check input levels.
Hearing Capability Tests
Sometimes the equipment is fine, but our ears are the limiting factor.
- Hearing Test: Check your age-related hearing loss.
- Ultrasonic Test: Can you hear above 15 kHz?
Troubleshooting Common Issues
| Problem | Likely Cause | Solution |
|---|---|---|
| Sound only on one side | Loose cable / Balance setting | Check connections; Check OS audio settings. |
| "Hollow" or "Thin" sound | Phase Cancellation | Your + and - wires might be swapped on one speaker. |
| Rattling noise | Blown driver / Loose screw | Run the Frequency Sweep to find the exact frequency that causes the rattle. |
| No Bass | Crossover settings | Ensure your receiver is sending LFE (Low Frequency Effects) to the sub. |
FAQ
How do I know if my speakers are "In Phase"?
Use our Headphone/Speaker Test. When playing the "In Phase" track, the sound should come from the center. When playing "Out of Phase," the sound should feel wide, hollow, and hard to localize. If "Out of Phase" sounds solid and centered, your wiring is reversed.
What is a "Flat Response"?
A "flat" frequency response means the speaker plays bass, mids, and treble at the exact same volume. This is the goal for studio monitors. Consumer speakers often boost the bass and treble ("V-shape") to make the sound more exciting.
Why does the Frequency Sweep get quiet at high pitches?
This is likely due to your hearing, not the speakers. Human hearing sensitivity drops off naturally above 15 kHz. Check your limits with the Hearing Test.
