Abstract
A computer method and system synchronizes one streaming data signal with another data signal. A subject data signal and working data signal are received. The working data signal has predefined coordinates in a coordinate system (e.g., time origin and unit sampling rate in a time coordinate system for audio). The subject data signal and working data signal are transformed into respective common representations. An alignment process aligns the respective transformed representations by matching the transformed representation of the working data signal to that of the subject signal. A re-synchronizer element transposes the predefined coordinates of the working data signal onto the subject signal in the aligned state of the respective transformed representations. As such, the subject data signal is synchronized to the coordinate system of the working data signal.
