# Audio Fingerprint Identification

The following schema describes how to define an audio fingerprint (AFP) identification task.

    [afpMatch]
    0 = a,ts <- audio(MONO, input)
    1 = fp <- afpfeature(_, a)
    2 = tr <- afp(_, fp)
    3 = output <- afpout(_, tr, ts)
    DefaultResults=out

`0` | The `audio` module processes the mono audio.
`1` | The `afpfeature` module converts audio data into audio fingerprint features.
`2` | The `afp` module matches features against a database of known tracks.
`3` | The `afpout` module writes the identification results to file.
