Sound test online — check your speakers

What is a sound test?

A sound test (also called an audio test or sound check) checks if your speakers or headphones are properly connected and working. This online audio tester plays test tones through the left and right channels so you can check sound audio quality, verify stereo balance, identify dead speakers, and confirm your audio setup is working. Unlike built-in OS tools, a browser-based sound test isolates playback issues—if your speakers work here but not in a specific app, the problem is likely in that app's audio settings or the audio source itself.

Online sound test features

A fast browser-based audio tester and speaker tester for checking left/right channels, stereo balance, and speaker output.

1. Left and right audio test: Test each speaker individually with a dedicated left right audio test. Click the left or right speaker icon to play a tone through that channel only and confirm it is working.
2. Stereo test mode: Play a tone through both channels simultaneously to verify stereo balance and check that both speakers are working together as part of your sound check.
3. Adjustable test tones: Choose from preset frequencies (bass, mid, treble) or use the slider to find the exact tone for your speaker test or audio test needs.
4. Volume control: Adjust the test tone volume directly in the sound tester to avoid sudden loud sounds and find a comfortable listening level.
5. Visual channel indicator: See which channel is actively playing with a highlighted speaker icon and pulsing "Playing" indicator during your sound test.
6. Wide frequency range: Use this audio tester across a full 20 Hz to 16 kHz range to evaluate bass response, mid-range clarity, and treble performance.

How to test speakers online

Three simple steps to test speakers and check your sound audio with this free online sound test.

1. Turn up your device volume: Make sure your computer or phone volume is turned up and not muted before starting the speaker test or audio test.
2. Select a test tone: Click Left, Right, or Stereo to play a tone. Adjust the frequency slider to test different sounds and check sound audio across the range.
3. Test each channel: Confirm you hear sound from the correct speaker. If only one channel plays during the left right audio test, you may have a connection or balance issue to troubleshoot.

Troubleshooting tips for sound testing

Common fixes if your speakers are not producing sound or if an audio test shows only one channel working.

1. Check speaker connections: Make sure your speakers are connected to power and plugged into the correct audio jack (usually green). For USB speakers, confirm the connection is secure before running another sound test.
2. Verify system volume and audio output: Check that your operating system volume is turned up and the correct playback device is selected. On Windows, check sound output settings. On macOS, check System Settings > Sound > Output.
3. Run a left right audio test for each channel: If you only hear sound from one side, click the Left and Right buttons individually. A silent channel on the audio test may indicate a loose connection, faulty speaker, or unbalanced settings.
4. Check speaker-to-speaker connection: For stereo speaker pairs, verify that the secondary speaker is properly connected to the primary one. Some models require a manual cable between the two speakers.
5. Update audio drivers: If no sound plays at all after a speaker test and you have verified connections and volume, try updating your audio drivers from your sound card manufacturer's website.
6. Test with headphones to isolate the issue: Plug in headphones to check if the problem is with your speakers or your device's audio output. If headphones work, the issue is speaker-related, not a system-wide audio problem.
