Title
(EN) SOUND EVENT DETECTION
(FR) DÉTECTION D'ÉVÉNEMENT SONORE
Abstract
(EN)
An audio processing system is described for an audio event detection (AED) system. The system includes a feature extraction block configured to derive at least one feature which represents a spectral feature of the input signal.
