Online Speaker and Headphone Test
Check your sound: left and right channels, stereo balance, frequency range, distortion and interference. Everything works directly in your browser.
🎧 How the Speaker Test Works
🔊 Signal Generation — Using Web Audio API, we create test tones and noise at different frequencies.
🎚 Channel Separation — Sound is played separately to left, right, or both channels to verify stereo functionality.
📈 Level Analysis — We measure RMS, peak values, and potential clipping (overload).
📊 Visualization — Waveform and volume indicators help you visually assess quality.
✅ Report — At the end, you get a quality assessment and recommendations: where weaknesses are — bass, treble, balance or volume.
🔍 What the Sound Test Checks
L/R Channels and Stereo Balance
Separate testing of left, right, and both channels helps you understand whether each speaker is working and if there's any volume imbalance.
Hz Frequency Range
Tests frequencies from 125 Hz to 16 kHz — low bass, midrange, and high frequencies. This helps assess where your system might be cutting or boosting sound.
⚠ Clipping and Distortion
When volume increases sharply, crackling, buzzing, and "dirt" may appear. The distortion test helps determine whether speakers can handle high volumes without overload.
🌫 Noise and Interference
White and pink noise help detect unwanted clicks, hissing, crackling, as well as issues with cables or Bluetooth connections.
🛠️ Common Problems and How to Fix Them
🔴 Sound Only in One Ear
- →Check if the headphones are inserted correctly (L/R) and firmly connected to the jack.
- →Open sound settings in your OS and ensure the balance isn't shifted fully left or right.
- →Try another device — the issue might be with the cable or plug.
🟠 Crackling and Buzzing at High Volume
- →Lower the volume in your player and system settings, don't turn everything to maximum.
- →Check for dust or damage to the speaker membrane.
- →If using an amplifier — reduce the gain.
🟡 Background Noise and Hissing
- →Disconnect unnecessary audio devices and speakers, leave only what you need.
- →Try a different USB port or power supply (relevant for active speakers).
- →For Bluetooth — reconnect the device and move it away from interference sources.
🔵 Weak Bass or "Flat" Sound
- →Check headphone fit — especially critical for in-ear models.
- →For speakers: move them away from walls or, conversely, place them closer — bass is highly position-dependent.
- →Disable aggressive equalizer settings that might be cutting lows or highs.
❓ FAQ
Can I take the test on a smartphone?
Yes, the speaker and headphone test works in mobile browsers. You can check both your phone's built-in speaker and any connected headphones.
Why can't I hear the 16 kHz sound?
This is normal: with age, the upper hearing limit decreases, and some headphones and speakers physically cannot reproduce such high frequencies.
How safe is the test?
All calculations and sound generation happen locally in your browser. No audio data is sent anywhere.
How often should I check my speakers?
We recommend taking the test when buying new headphones/speakers, after updating drivers, and if you notice changes in sound quality.
The test shows problems, but everything sounds fine. Should I worry?
Not necessarily. If you don't hear artifacts in normal use, you can treat the test as a "strict teacher." However, for professional audio work, it's better to rely on these metrics.
