What Speaker Test does
Play left, right and both-channel tones plus a 20 Hz to 20 kHz sweep.
The workflow runs on this device. Where a tool remembers state, it uses this browser’s local storage rather than a ToolkitPoint account. For Speaker Test, the operation is specifically to play left, right and both-channel tones plus a 20 Hz to 20 kHz sweep.
Worked example
With earbuds in, press "Play left": a 440 Hz tone should come only from the left bud. Then run the sweep: the Frequency box climbs from 20 Hz to 20 kHz over 20 seconds, and small earbuds typically become audible around 50-80 Hz.
When Speaker Test is the right tool
- Checking a new pair of earbuds or speakers for a dead channel.
- Making sure a surround or stereo setup is wired left and right correctly.
How to verify the result
Try the primary action and the reset or remove action before relying on the tool during important work. The final Speaker Test output should visibly match this goal: Play left, right and both-channel tones plus a 20 Hz to 20 kHz sweep.
Important limitations
Sound plays through the system's default output device; switch outputs in your operating system settings. Hearing range and speaker size both limit what you hear at the extremes.

Frequently asked questions
Left and right are swapped. What now?
Earbuds or headphones may be worn the wrong way round, or the system has a swapped balance or mono setting. Check the L and R markings first, then the audio balance in your system sound settings.
Why can't I hear the start or end of the sweep?
Small laptop and phone speakers rarely reproduce much below 100-150 Hz, and many adults hear little above 15-17 kHz. The sweep shows the frequency live so you can note where your setup fades.
Can I choose which speaker device plays the sound?
The page plays through the default output device. Change the output in your system sound settings (or the Bluetooth menu) and press Play again.
Is the test loud?
The slider starts at 30 percent of a gentle level and the tones are plain sine waves. Still start with low system volume, especially with headphones, and raise it slowly.
Does it work with Bluetooth headphones?
Yes. Bluetooth adds some delay, so the tone may start a moment after you press the button, but left, right and the sweep work the same.
