AudioContext
AudioContext fingerprinting (also known as “audio fingerprinting”) is a browser fingerprinting technique that generates audio signals using the Web Audio API and leverages subtle differences in a device’s audio processing pipeline.
Due to variations in hardware, operating system audio stack, drivers, and browser implementations, identical audio processing operations may produce slightly different outputs across devices.
These variations can be collected and converted into feature values, which are used as part of device fingerprinting, commonly referred to as an AudioContext or audio fingerprint.
This process typically runs in the background without the user’s awareness during normal browsing.
Steps:
- Click the Create Browser button on the main client interface.
- In the profile configuration panel > Fingerprint > AudioContext.
- Random: Each browser on the same computer generates a different Audio.
- Close: Each browser uses the default Audio of the current computer.
