A system for audio summarization in acoustic monitoring scenarios

A system for the acoustic monitoring of relevant audio events in real-life outdoor recording environments is presented. Targeting such realistic scenarios relies on the usage of robust and effective audio signal processing methods. In this paper, we address the key aspects of a corresponding audio monitoring system comprising an array of innovative acoustic sensors providing bearing information, robust, unsupervised methods for both detecting and localizing audio events, the integration of the acquired data streams, and a novel user interface for the audio-visual browsing of recorded audio scenes and detected audio events therein.
