SPATIAL AUDIO TEST
ReadyFollow the moving sound
A continuous source travels around the listener using browser spatial audio.
CURRENT DIRECTIONFRONTOne full orbit takes about 6.8 seconds.
Best experienced with headphones. This test simulates spatial audio using your browser. It does not verify physical 5.1 or 7.1 surround speaker channels.
Perceived direction can vary by browser, headphones, and individual hearing.
FREQUENCY TEST
Check different sound ranges
Play short pure tones through your current audio output.
Selected FrequencyAdjust across a logarithmic range of 80–8000 Hz.
1000 HzOutput level follows the shared Speaker Test control. Perceived loudness varies by device and frequency.
Start at a low volume, especially with headphones.
Small laptop speakers may reproduce bass poorly. An inaudible tone alone does not confirm a speaker fault.
How to test your speakers online
Prepare your speakers or headphones
Set your system volume low and connect the speakers or headphones you want to check. Test tones play through your current audio output.
Play a channel or sound test
Use Stereo to play a tone through the left, right, or both channels. Try Spatial for moving sound or Frequency for preset and custom tones.
Listen and compare
Check whether left and right tones come from the expected sides. Spatial direction can vary by browser and headphones; these listening checks do not diagnose hardware faults.
