Title
Konzept zum Erkennen eines akustischen Ereignisses in einer Audiosequenz
Other Title
Device for recognizing unusual acoustic event in audio recording, has detection device detecting acoustic event based on error vectors, which describe deviation of test vectors from approximated test vectors
Abstract
The device has a determining device (102) for determining multiple test vectors based on an audio sequence (110). A provision unit provides a code book with multiple support vectors. An approximating device approximates the test vectors based on the support vectors to approximated test vectors, where error vectors describe a deviation of the test vectors from the approximated test vectors. A detection device detects an acoustic event based on the error vectors and determines a point of time of detection of the acoustic event. Independent claims are also included for the following: (1) a method for recognizing an acoustic event in an audio sequence (2) a computer program comprising a set of instructions to execute a method for recognizing an acoustic event in an audio sequence.
