The recordings must be decomposed, i.e. they must not contain any components. Factor is typically between 0 and 1. 0 means the first recording, 1 means the second recording, and 0.5 means the average of the two recordings. Other values are possible, and can be useful to extrapolate. Defaults to 0.5.
