Frequently asked questions
What does this test check?
The test shows microphone input level, lets you make a short recording and play it back, and helps confirm that the device is working.
Do I need to install anything?
No. The test runs directly in a supported web browser.
Does ACC64 save my test results?
No account is required. Hardware tests run locally in your browser unless a tool clearly requires a server connection, such as the Internet speed test.
