Question 1

What does the speaker test check?

Accepted Answer

It checks left channel, right channel, both channels, bass response, treble response, and a frequency sweep from low to high tones.

Question 2

Should I use headphones?

Accepted Answer

Headphones are recommended for left and right channel checks because they make stereo separation easier to hear.

Question 3

Why can I not hear the high frequency tone?

Accepted Answer

Some speakers, headphones, and ears cannot reproduce or hear very high frequencies. Lower the volume first, then test carefully.

Question 4

Does the speaker test record anything?

Accepted Answer

No. It only plays generated tones in your browser and does not capture or upload audio.
