Speaker Test
Play a safe test tone after you click, confirm you can hear it, and choose an output device where supported.
Did you hear the tone clearly?
01How this test works
Audio tests run entirely inside your browser. For microphone tests, your browser listens to the live sound coming from your mic; for playback tests, the page creates clean test tones and sends them to your speakers or headphones.
Everything is measured on your device. The level meter, the waveform and the frequency view are all worked out from the live sound as it happens. None of this audio is recorded, saved, or sent anywhere.
Playback tests always start silent and only make sound after you press a button, so a page can never blast audio at you when it loads. Any sound stops the moment you press Stop, leave the page, or switch to another tab.
02How to use it
- Press the start or grant-access button — the browser will ask for microphone permission only for input tests.
- For microphone tests, speak or make noise and watch the level meter, waveform and spectrum respond.
- For playback tests, start at a low volume and raise it gradually, especially with headphones.
- Use the on-screen controls to select a device, change settings, or play reference sounds.
- Press Stop when you are done to release the microphone and silence any tone.
03What this test covers
What it detects
- Whether your browser can access the device and receive a signal at all
- Relative input level, clipping, and silence on the microphone
- The browser-reported sample rate, channel count and processing settings
- Whether you can subjectively hear a generated tone through your speakers or headphones
What it can’t detect
- Calibrated loudness in decibels (dB SPL) — browsers expose only relative amplitude
- A microphone’s or speaker’s certified frequency response or hardware specifications
- Hardware faults versus driver, routing or operating-system configuration issues
04Troubleshooting
| Symptom | What to do |
|---|---|
| No permission prompt appears | Check that the site is on HTTPS and that your browser hasn’t already blocked the microphone in its site settings (padlock icon). |
| The level meter stays flat | Pick the correct input device from the selector and make sure it isn’t muted in your operating system. |
| Constant clipping | Lower the input gain / microphone level in your OS sound settings, and move away from the mic. |
| Echo or noise | Use headphones to avoid the speaker feeding back into the mic, and reduce background noise. |
| Device is busy | Close other apps (video calls, recorders) that may be holding the microphone, then retry. |
05FAQ
Does this upload my audio?
No. All analysis happens locally in your browser and nothing is recorded or uploaded.
Why can’t I see exact decibels?
Browsers expose a relative signal level, not calibrated sound pressure. Showing dB SPL would require lab calibration that isn’t possible in a browser.
Do I need to install anything?
No. Everything runs in a modern browser with no installation, plugin, or account.
Why does it need HTTPS?
Browsers only grant microphone access on secure (HTTPS) origins to protect your privacy.
Can I use these tests on my phone?
Yes. The audio tests work in mobile browsers, though available devices and settings vary by platform.
Is it safe for my hearing and speakers?
Playback starts quiet and never autoplays. Still, keep the volume moderate — especially with headphones and at very high or very low frequencies.
