Time Synchronisation

Synchronize two tables in time by matching features of selected signals.

Documentation

Synchronizes two tables in time by selecting a signal in each table and then finding the time offset at which the features of those two signals overlap the most. The node uses cross-correlation internally to find the offset, hence the signal features needs to be similar in shape, but scale doesn’t matter.

Note that the resulting time offset will always be a multiple of the smallest time step of the two signals.
