# Overview

Audio fingerprint (AFP) identification is the process of analyzing audio data to identify occurrences of known audio clips, such as specific pieces of music or particular adverts. This process is useful for detecting when specific adverts occur, to check for copyrighted music being played, to pick out commercial jingles, and so on.

The first step is to build a database of the audio clips to identify. Each clip is represented in the database by a sequence of distinctive features. Speech Server can analyze incoming audio to detect occurrences of the stored clips. Speech Server compares the target audio to the database clips and identifies sections that closely resemble the database clips.
