Browsers can use audio files to identify web visitors, a technique known as audio fingerprinting. Apple introduced advanced fingerprinting protection in Safari 17 to combat this, adding noise to audio samples to prevent identification. This protection affects the Screen API and Canvas API, but in this article, we focus on the Audio API. By adding noise and changing the audio signal, Safari breaks the stability of the fingerprint, making it unusable for identification. To bypass this protection, a new algorithm is introduced that combines multiple audio fingerprints to reduce noise and improve accuracy. Changing the base signal also helps push browser identifier numbers farther apart, increasing the differences between browsers.
