This paper presents a robust audio retrieval method. In the method, the retrieval target is
divided into short segments, each segment is searched respectively, and a retrieval window is
used to maintain a list of segments that can be searched simultaneously. The method can quickly detect and locate known sound in real‐time audio stream, multimedia archives or the Internet. It can maintain high performance even if large part of target is absent in the input stream. Its retrieval speed can be adjusted by the length of retrieval window and is independent on target length. The recall rate and precision rate of the method are 100% and 99.7% respectively.
