Ted,

see package tuneR for reading Wave files.

For F0 and spectograms see also tuneR.


"Formants" is a bit more tricky. We tried some analyses, but since the 
definition of a formant is still not completly clear to me, we haven't 
provided anything for formants in the package yet. Do you know some good 
literature that gives a somwhat precise definition? At least musicias 
only talk about something like "raised" areas in the periodogram, which 
is not very helpful given the missing definition of "raised".
