[Question] Sound fingerprint match always a few seconds/milliseconds too early majority of the time about soundfingerprinting

Hello, have you tested, if I have 1 million songs, is the speed slow when users go to match search? How accurate is it?

@sezonis The algorithm has a certain level of matched accuracy which cannot be improved due to various non-trivial reasons. A worst-case scenario (under ideal conditions of having the same source/target track as the query) can yield about 500ms of misalignment.

Fair enough. It's pretty damn accurate I must say, being dead on accurate would have been A+.

No idea I don't use a database as I don't need to for my use case.
