Abstract (en)
[origin: WO2021151915A1] The invention relates to a method (100) for detecting anomalies, comprising the following steps: obtaining a long-term recording (113) containing a plurality of first audio segments (ABCD) each allocated to respective first time windows; analysing the plurality of first audio segments (ABCD) to obtain for each of the plurality of first audio segments (ABCD) a first feature vector describing the respective first audio segment (ABCD); obtaining a further recording (123) containing one or more second audio segments (ABCD) each allocated to respective second time windows; analysing the one or more second audio segments (ABCD) to obtain one or more feature vectors describing the one or more second audio segments (ABCD); comparing the one or more second feature vectors with the plurality of first feature vectors to identify at least one anomaly, such as a time, tonal or spatial anomaly.
