# Audio Security

The following schema describes how to use the `audiosec` module for audio security processing.

    [AudioSecurity]
    0 = a ← wav(MONO, input)
    1 = f ← frontend(_, a)
    2 = nf ← normalizer(_, f)
    3 = w1 ← audiosec(_, a, nf)
    4 = output ← wout(_, w1)

`0` | The `wav` module processes mono audio.
`1` | The `frontend` module converts audio data into speech front-end frame data.
`2` | The `normalizer` module normalizes frame data from `1` (`f`).
`3` | The `audiosec` module processes the audio (`a`).
`4` | The `wout` module writes the security issue label information to the output file.
