Abstract
An audio registration method based on dynamic time-warping (DTW) technique was described in this paper. DTW technique can register two audio signals whose type of misalignment in time domain is unknown. By measuring the frame dissimilarities in two audio signals, the best alignment between a pair of audio signals can be obtained to register the two audio signals. This method can solve the registration problem for audio signal which is processed by re-scaling in the time domain. It is useful in many audio applications and has been applied to digital audio watermarking detection.
