The extraction of information from audio files has applications in the detection and classification of musical segments, timbres and biometrics, and the appearance of anomalies in an audio track.

Analysis of spectrograms with neural networks transcends traditional tape analysis based on transcription to text, enabling nuances to be extracted which may help detect important information in the audio file.
