What would you like to test?
Two focused tools. Check the sound you hear, or the voice your microphone receives.
Stereo speaker test
Find your left. Hear your right. Check your speakers or headphones, one channel at a time.
Open test →Microphone test
Make sure your voice is coming through. Start a private, local input check when you are ready.
Open test →Which audio test should I choose?
Choose the speaker test to play a tone and compare left and right output. Choose the microphone test to check whether the browser receives your voice and observe its input level. Both tools are free. Start with low playback volume; microphone monitoring is optional and works best with headphones to reduce feedback. These checks help compare settings and connections, not certify hardware health.
