Audio diagnostic
Test your audio chain
Three checks: what audio devices your browser sees, a five-second read of your mic's noise floor and tonal shape, and a real measurement of your round-trip latency. Honest numbers, no guessing.
PrivacyEvery test runs entirely in your browser. No audio is uploaded, recorded, or stored anywhere.
Test 1 · Devices
What Patchd would see
Every audio device your browser exposes. Names are hidden until you grant mic access (browser security).
Test 2 · Microphone
Five-second mic check
Records 5 seconds of raw mic input and reports peak, noise floor, clipping, and tonal shape. Speak normally for the first couple seconds, then stay quiet so we can read your noise floor.

Test 3 · Latency
Round-trip latency
Plays a short click through your speakers and listens for the echo on your mic. The delay between the two is your real round-trip latency.
- · Speakers must be on. Headphones won't produce an echo.
- · Turn your speaker volume up to a normal listening level.
- Pause any music or background audio. The room needs to be quiet for the measurement to be accurate.
- · Stay quiet for about a second after you press start.
- · You'll hear a single short beep. That's the test.
