Those who have nothing to say, have nothing to fear.

https://audiofingerprint.openwpm.com/ This page tests browser-fingerprinting using the AudioContext and Canvas API. Using the AudioContext API to fingerprint does not collect sound played or recorded by your machine - an AudioContext fingerprint is a property of your machine's audio stack itself. If you choose to see your fingerprint, we will collect the fingerprint along with a randomly assigned identifier, your IP Address, and your User-Agent and store it in a private database so that we can analyze the effectiveness of the technique. We will not release the raw data publicly. A cookie will be set in your browser to help in our analysis. We also test a form of fingerprinting using Flash if you have Flash enabled.
