To clarify - the FFT results cannot be cached after the first call in 
the iteration and returned when the other frequency params are queried 
as the incoming samples must be modified with the supplied params first 
and then the FFT is calculated - it is all part of the function.

I may have to write my own specific-case implementation, using the 
lower-level optim functions.

Thanks a lot for any hints,

Pavel.
