Measuring unique audio characteristics of your device
Audio fingerprinting identifies devices based on unique characteristics in their audio processing. By analyzing how your device processes sound, we can create a unique identifier for your device.
We generate a 440Hz sine wave and analyze how your device processes it. Differences in hardware, drivers, and browser implementations create measurable variations in the output.
Your fingerprint ID is derived from your device's unique audio characteristics. This ID can potentially be used to recognize your browser across websites without cookies.
The uniqueness percentage indicates how distinctive your audio fingerprint is compared to other devices. A higher percentage means your device is more easily identifiable through audio fingerprinting.
Audio fingerprinting is a passive technique - no permissions required
