Speaker Test

This sound test plays short signals through your device’s audio output. Listen for whether sound comes from the left, right, or both sides, and whether each side sounds clear and distinct. The signals contain no speech.

You can choose an output device when your browser allows it. If it does not, the page shows a note. Start with the volume low, then raise it only as needed to hear the signals. This test checks playback; it does not test a microphone.

The channel test sends pink noise and a tone pattern to each channel. One beep means the left channel; two beeps mean the right channel. The both setting plays through both channels. If a sound seems to come from the wrong side, check your device’s channel setting and output choice.

The polarity check plays noise in phase and out of phase. These describe how the two channels line up with each other. Compare the two sounds: a noticeable change can indicate that the channels are behaving differently, but the page does not give a pass threshold.

The sweep covers 20 Hz to 20 kHz, and the current frequency is shown as it plays. Listen for changes, gaps, or rattling as the tone moves through frequencies. The shown frequency tells you what part of the sweep is playing; it is not a score of speaker quality.

If there is no sound, or one side is missing or swapped, first check that the selected output is the one you want and that your device volume is audible. If the browser cannot offer output selection, use its note to understand that limitation. A weak or uneven sound can also come from the selected output or the device’s audio settings.

For no sound, this page links to a fix guide. Open the guide for next steps. If only one channel or part of the sweep sounds different, repeat the test at a low volume and compare the left, right, and both settings.

The page creates separate, short signals for each channel, including pink noise, a tone pattern, and beeps. It uses the audio output path available in the browser to send left and right signals, then plays noise with the channels in phase and out of phase for the polarity check.

For the sweep, the tone changes across 20 Hz to 20 kHz and the page displays the frequency. The test starts at a low volume. Output-device choice appears only where the browser provides that option.
