Sound Test - Check Your Speakers & Headphones Online

Use the 'Left channel' and 'Right channel' buttons to play test tones through each speaker individually. You should hear sound from only one side at a time. If both channels play from one speaker, or one side is silent, you may have a wiring issue, incorrect balance settings, or a faulty speaker/headphone. The 'Alternate L/R' mode automatically switches between channels for quick verification.

Yes, click 'Start monitoring' in the Microphone section to grant browser access to your mic. You'll see a real-time level meter showing input volume and a peak hold indicator. This helps you verify your microphone is working and properly positioned. All audio processing happens locally in your browser—nothing is recorded or uploaded to any server.

The frequency sweep plays a tone that gradually rises from 20Hz (deep bass) to 20kHz (high treble). This helps you identify any frequencies your speakers cannot reproduce, hear distortion at certain frequencies, or detect rattling objects on your desk that resonate at specific frequencies. It's also useful for testing subwoofer bass response and checking if your audio equipment covers the full audible range.

White noise has equal energy at all frequencies, making it sound 'hissy' like TV static. Pink noise has equal energy per octave, which sounds more balanced to human ears and more closely resembles the frequency spectrum of typical music. Pink noise is often used for audio calibration and speaker testing, while white noise is useful for hearing high-frequency hiss or detecting specific audio problems.

If you can't hear frequencies below 80-100Hz, your speakers or headphones likely cannot reproduce deep bass. Laptop speakers and small earbuds typically don't reproduce frequencies below 150Hz. Bass requires larger speaker drivers or headphones with good low-frequency response. Subwoofers are designed specifically for bass reproduction (20-80Hz). The frequency sweep test helps you determine the lowest frequency your audio equipment can clearly reproduce.

To do a quick sound check, click the 'Left channel' or 'Right channel' button on this page. If you hear clear audio from the correct speaker, your sound is working. You can also use the frequency sweep to test bass and treble response, or the noise generators for a full-range sound check. No software installation is needed—this sound test runs entirely in your browser on any computer, laptop, or mobile device.

Yes, this tool works as a headset test for any wired or wireless headset. Plug in or pair your headset, then use the left/right channel buttons to verify both ear cups produce sound. The stereo test confirms channels aren't swapped. You can also test your headset's built-in microphone using the mic monitoring section. Works with gaming headsets, Bluetooth headsets, and USB headsets on any platform.

To test if your speakers are working, click the play buttons on this page to send test tones to your left and right speakers individually. If one speaker is silent, check your cable connections, audio balance settings, and make sure the correct output device is selected in your system settings. The frequency sweep can also reveal if your speakers have limited range or distortion at certain frequencies.
