MODERATORS
If it's part of a fingerprinting lib, then they just fucked it up. Because the fingerprinting can be done in one ~16ms window of time when the script runs and then you can break down the audio objects and pretend nothing happened.
Also because browsers support OfflineAudioContext, which lets you do the same things but doesn't try to output to speakers.
This guy fingerprints.
(hopefully in a good way)
Oh gods. I leave them everywhere 🤷
