For each frequency bin in the CSD stack the implementation extracts the (optionally real-cast) cross-spectral density, calls into InvBeamformerCompute to derive the spatial filter, and stores the result in the InvBeamformer container. The application methods then re-project new CSDs (source-power) or new time-domain data (narrow-band time-course) through the cached per-frequency filters.
