# Assess Audio Quality

The following schema describes how to use the `audiopreproc` module to assess audio for clipping and to measure the signal-to-noise ratio.

    [AudioQuality]
    0 = a ← wav2(MONO, input)
    1 = output ← audiopreproc(CS,a)
    DefaultResults = log

`0` | The `wav` module processes the mono audio.
`1` | The `audiopreproc` module, set to use clipping detection mode (`C`) and signal-to-noise ratio calculation mode (`S`), processes the audio (`a`). The results are written to an output file.
