Building an AI-based Sound Event Classifier

Introduction

The term Sound Event Classification (SEC), also called Acoustic Event Classification or Audio Event Classification, is the process of acquiring audio signals from an audio source, analysing the acquired signals to detect events that we are interested in and if an event is detected, categorizing the event, which will be used to trigger actions by the downstream components or referred to consumers for further analysis and actions. As an example, law enforcement agencies can use the sound inputs from microphones attached to street cameras.
