Browser Fingerprint：AudioContext

An AudioContext fingerprint (also known as an "audio fingerprint") is a hash derived value of the device's audio stack. Here's how it works. Depending on your audio Settings and hardware, the Web site asks your browser to simulate the way it plays an audio file as a sine function. This sine function is converted to a hash function and sent to the server as additional entropy in the browser fingerprint recognition.

In Migratory Bird Browser, random persistent noise is automatically added to your browser environment to control the readout of the AudioContext, and the website does not take the real audio fingerprint of your device.
