Pick the right subject line

One mailbox handles everything, but a clear subject gets a faster answer. These links fill it in for you:

• Report a bug in the testThe meter, recorder, headphone tones or latency test behaving incorrectly.
• Suggest a correctionSomething in a guide is wrong, out of date, or no longer matches your operating system.
• Request a featureA test or measurement you wish this page offered.
• Privacy requestAnything covered by our privacy policy.

What to include

If you are reporting a problem with the test itself, the fastest way to help us is to open the Report panel on any test page, press Copy report, and paste the result into your message. It contains the device name, sample rate, channel count, processing state and browser version — everything needed to reproduce a fault.

What we cannot do

We cannot repair hardware, supply drivers for specific devices, or access your machine. For a microphone that fails on every computer you try it on, the manufacturer's warranty support is the right route.

Response time

Email is read on weekdays and most messages get a reply within a few days. Bug reports with a copied report attached are prioritised.
