More Information
Summary:An audio signal classifier including a feature extractor to extract metadata from an audio signal, the metadata defining a plurality of features of the audio signal, the feature extractor to generate a feature vector including selected features of the audio signal, the selected features including a duration of the audio signal, and each selected feature having a feature value. A machine learning model trained to classify the audio signal as one of a plurality of audio signal classes based on the feature vector. The machine learning model to provide a plurality of class values based on the feature values, each class value corresponding to one of the plurality of audio signal classes, the plurality of class values together indicating the class of the audio signal.
