Probably implementation details and compiler optimizations, float addition is not commutative for example. Implementing the same algorithm with the same formula

Probably implementation details and compiler optimizations, float addition is not commutative for example. Implementing the same algorithm with the same formulas correctly can still lead to slightly different results

Floating point addition is not commutative, but it is still consistent. Getting different results is usually the result of using alternative algorithms or relaxing standards (that may, for example, reorder terms).

  I don’t think the web spec implemented by the browser specifies the order of every operation, only the algorithm. If safari and chrome devs implement the audio api based on the spec, there can still be minor floating point differences because of the way they implemented the same calculations. That’s why they can fingerprint your browser versions with this.

I would have thought it might have yielded a machine and OS identifier - but more user specific than that?

  That’s what it does, users on the same browser and same hardware should have identical fingerprints. It’s just one way of multiple to narrow down your fingerprint.

    Thanks for the clarification - much appreciated
