It would be nice if FieldTrip would have a consistent set of low-level functions for spectral estimation of EEG and MEG data. This would allow other projects to re-use the implemented methods seperate from FieldTrip (e.g. for realtime analysis of EEG and MEG data) and perhaps also to contribute to FieldTrip.

The low-level functions are combined in the specest toolbox, which is available for download here. At the moment the specest toolbox does not contain much.
