Home Speaker Test
Left & Right Stereo Channels
Check left and right channels on computer speakers, headphones and home audio systems. Run a stereo test, check bass playback, or select 5.1 or 7.1 for a compatible surround setup.
Connection help
Select a speaker or preview all channels · No audio
Stereo 2.0 · Ready · No audio
Start with a low volume on your speakers. Bass is a separate test.
Advanced settings
If side and back speakers are exchanged, select the other order and test again. Confirm positions by listening; 8 available outputs alone do not verify a 7.1 setup.
How to run a left right speaker test
Connect your computer speakers, headphones or home audio system and select that output in your device settings. Turn off mono audio and start at a low volume. Choose Stereo for a standard AUX or Bluetooth connection.
Choose Left or Right and listen from your normal seating position. The voice and tone should come from the selected side. Stereo plays the same signal through both channels. Each sound test lasts 15 seconds; use the progress slider to replay a section or Stop to end it.
Test All plays Left, Right and Stereo in sequence, 15 seconds each. Use Bass separately to check low-frequency playback on your speakers or 2.1 system.
Surround sound test for 5.1 and 7.1 systems
Select the layout that matches your home audio system, then choose a speaker or run Test All Channels. Each full-range channel plays a tone with its spoken name three times. SUB plays an 80 Hz tone through the separate LFE channel without a voice announcement.
A surround sound test needs a compatible multichannel output configured in your system settings. The page checks how many output channels the browser exposes before starting. You still need to listen to confirm that each sound reaches the correct physical speaker. If your output supports only stereo, you can view the channel sequence without sound.
Home speaker check: questions and troubleshooting
What does this speaker test check?
It helps you check left and right channel assignment, hear whether a selected speaker plays, and check bass playback. On a compatible surround system, you can test individual 5.1 or 7.1 channels. This is a listening check, not an automatic measurement of sound quality, frequency response or room calibration.
Why do left and right play from the same speakers?
Check that mono audio is off and that you selected the intended audio output. A soundbar or receiver may spread stereo sound across several speakers using a surround effect. Select its standard stereo mode for the left right speaker test and check your connections if the sides still do not match.
Can I test computer speakers and a 2.1 system?
Yes. Choose Stereo for two computer speakers or a 2.1 system connected through a standard stereo output. Left and Right check the two channels. Bass sends an 80 Hz tone through both; your audio system decides how to route low frequencies to its subwoofer. This does not address the subwoofer independently.
Can I use this stereo test with headphones or a Bluetooth soundbar?
Yes. Select your headphones or soundbar as the audio output, then check Left, Right and Stereo. An ordinary Bluetooth audio connection carries stereo for this test. A soundbar may distribute the bass to its own subwoofer, but that does not turn the connection into separate 5.1 or 7.1 channels.
Why is the 5.1 or 7.1 sound test unavailable?
The browser may expose only two output channels. Select and configure a compatible multichannel audio output, such as a suitable HDMI or USB device, then reload the page. The test needs six available channels for 5.1 or eight for 7.1. The visual preview remains available without multichannel audio.
Why is there no sound from a selected speaker?
Check the selected audio output, browser mute setting, test volume and your amplifier or speaker volume. Check cables and receiver channel settings. If other channels work but one stays silent, compare with your receiver's built-in speaker test to help locate the problem.
How is Bass different from SUB?
Bass in Stereo mode sends low frequencies through left and right together. SUB in surround mode sends an 80 Hz tone only to the LFE output. A silent SUB test alone does not prove a faulty subwoofer: the receiver settings and output routing also matter. Neither test checks Dolby Atmos or DTS decoding.
To check a phone's built-in speaker, use the separate phone speaker test.
