Abstract
(EN)
A computer-implemented method of matching of a first incoming audio track with an indexed audio track, the method executable at a server, the method comprising: selecting the indexed audio track as a candidate audio track from a plurality of indexed audio tracks; validating the candidate audio track against the first audio track.
