Does it work on a sliding window ? Does it estimate the cospectrum (the real part) and the quadrature spectrum (complex), the coherence squared, and the phase difference between two vector time series ? SOme time ago I started to read its author's thesis. It seemed to me strictly tailored on the specific problems he studied more than a wider purpose toolkit.
Maura have you tried sowas? I know you had talked about it, but it may do what you want. I have used it for the wavelet cross spectrum.
