Yes. Our free online mic test works on the same browser that Skype Web runs in, and tests the exact same microphone device that your Skype desktop app uses — because both share the OS default input device. If our test passes, your microphone hardware is working correctly for any Skype application. If Skype still fails after passing our test, the issue is inside Skype's audio settings — see the Setup Guide section above.

Never. All audio processing happens entirely inside your browser using the Web Audio API — a browser-native technology. Zero audio bytes are transmitted to our servers. This is a technical guarantee: open your browser DevTools (F12) → Network tab while running the test and you will see zero audio upload requests. Your microphone data exists only in your browser's local memory and is discarded when you close the tab or stop the test.

This is almost always a Skype permission or device selection issue, not a hardware problem. The most common causes are: (1) Windows/Mac privacy settings blocking Skype's access to the microphone — go to OS Settings → Privacy → Microphone → enable for Skype; (2) Skype's microphone is set to "Same as system" but the system default was reset — explicitly select your mic by name in Skype Settings → Audio & Video; (3) Skype needs to be fully restarted after a permission change. Our test proving the hardware works is actually the key diagnostic information that tells you to look inside Skype, not the hardware.

Yes — with one important note. On iPhone and iPad (iOS), use Safari exclusively — Apple restricts microphone access to Safari only; Chrome, Firefox, and other browsers on iOS cannot access the microphone due to Apple's WebKit policy. On Android, use Chrome for the most reliable test. No registration required on any mobile device. The test confirms your built-in phone mic, Bluetooth headset, or any connected audio device is working for Skype mobile calls.

For Skype calls, the ideal microphone level during normal conversational speech is between −30 dB and −12 dB. Below −40 dB means you are too quiet and the other party will struggle to hear you clearly — raise your OS input volume or enable Microphone Boost. Above −6 dB means you are too loud and will sound distorted/clipped on Skype — lower your OS input level or move the mic further away. The goal is consistent speech peaking between −20 dB and −12 dB.

Yes. Pair your Bluetooth headset fully in your OS Bluetooth settings before opening the test page. Your headset should then appear in the device selector dropdown. Make sure your headset is in Headset/HFP (Hands-Free Profile) mode — not just Media Audio mode, which disables the microphone. One important note: Bluetooth adds 100–300ms of codec latency inherent to the wireless protocol — this is normal hardware behaviour and not a fault with the tool or your Skype setup.

All modern browsers require explicit user permission before any website can access your microphone — this is a browser security feature mandated by the W3C Web Standard. This is not unique to our tool — every website that uses a microphone must request this permission. Clicking Allow grants temporary access for this session only, and you can revoke it at any time via the lock icon in your address bar. Our tool uses this access solely to run the local audio analysis — no data is recorded or transmitted, as detailed in our Privacy Policy.

If our free online test passes (confirming your microphone hardware and browser access are working), the problem is in the Skype application layer. Check these in order: (1) Skype Settings → Audio & Video → your specific mic is selected, not "Default"; (2) OS privacy settings allow Skype to access the microphone; (3) Skype hasn't muted you (check the mic icon during the call); (4) Your Skype isn't in "Do Not Disturb" mode which suppresses audio; (5) Ask the other caller to leave and rejoin the call — sometimes Skype's audio stream needs to be reinitialised. Also confirm with Skype's own Echo / Sound Test Service call (search "Echo" in Skype contacts) to hear how your voice sounds from Skype's network.
