> It added it had received the microphone data only as code rather than audio, and that it could match that code with audio data from a match.

That sounds funnily absurd to me. By that line of argument, even sound is not really audio. After all, it's being encoded as air pressure waves :-)

EDIT: Pardon my ignorance. Based on Google Translate's translation of their statement [1], it seems that they are using some kind of perceptual hashing which is quite interesting.

I guess they mean that they just have a summary of the sound, not enough to listen to it or anything. It would be a bit like just having the hash of a piece of data, not the data itself.
