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.

[AudioAnalysis]
0 = a,ts <- audio(MONO, input)
1 = f <- frontend(_, a)
2 = nf <- normalizer(_, f)
3 = w <- audiopreproc(ACS, a, nf)
4 = output <- wout(_,w,ts)
0 The audio module processes the mono audio.
1 The frontend module converts the audio data from 0 into front-end frame data.
2 The normalizer module normalizes the frame data from 1.
3 The audiopreproc module, set to use audio classification (A), clipping detection (C) and signal-to-noise ratio calculation (S), processes the audio (a) and normalized frame data (nf).
4 The wout module writes the results to an output file.
