Visualizing Audio for Anomaly Detection

Mark Hasegawa-Johnson, Thomas Huang, Hank Kaczmarski, Camille Goudeseune

Rendering a large audio recording as an interactive visualizations
lets an analyst uncover important anomalies therein,
thousands of times faster than listening in "real time."
To guide the analyst away from uninteresting data, we will
display both audio-derived and hypothesis-based features
of the raw acoustic signal. The analyst can then zoom continuously,
either in time or in time and geographical space, into interesting
areas for deeper investigation. These derived features generalize
from audio to other time series, either standalone or geotagged.
