LifeLog can be used as a stand-alone consumer device to serve as a powerful automated multimedia diary and scrapbook. By using a search engine interface, the user can easily retrieval a specific thread of past transactions, or recall a few seconds ago or from many years earlier in as much detail as is desired, including imagery, audio, or video event. In this paper, we have studied and implemented three audio classification algorithms. The testing results show that KNN is the best classifier to classify the multimedia data.
