When we save the sdif file we are in fact saving the minimum information
required for synthesis: the residual spectrum and the sinusoidal peaks.
This is less than what is needed for visualizing the "frame analysis
data". For that reason when loading from sdif we deactivate that option.
This is in fact an application logic bug that should be addressed in the
near future but for now that is what we have :(

Uhm, what does it mean that int cannot be synthesized back. Isn't the
menu option enabled? Do you get some kind of error?

XML is a very verbose and unefficient format. You should expect it to
take a lot of time and memory space if the sound is relatively long.
What is not so normal is that it gives you some errors: what kind? do
you get any message on the console? is it a system error?

Thanks for your feedback.
