Important notice:
This site and all of its tests are provided free of charge and on an experimental basis.
We are not responsible for any damage, instability, crashing or overheating caused to your computer
during or after running the tests. Use responsibly — if your system shows signs of instability,
stop the test immediately.
Tips: If you don't hear anything, check your system volume. For the frequency test, very high tones (8–20kHz) are normal to not hear depending on your age and headphones. The microphone only works with permission granted to the browser. Voice recording runs 100% in your browser — no audio is sent to servers — and the "Record" button works even if you haven't started the live monitor first.
