how can i transform a SDIF file (for instance exported from Spear) to 
Csound's PVOC-EX format?

Last time I did any work on SDIF things was something like 16 years ago. 
There was no sign then of a phase vocoder SDIF format, as such - raw FFT 
frames "1STF", and partial tracks "1TRC". A cursory check of the 
relevant web pages suggests nothing has been developed more recently.

Can you give information on exactly what the SDIF file data from Spear 
comprises? I suppose a 1STF file could be converted to pvocex, if the 
timestamps indicated both sufficient and constant frame overlap. If it 
is partial track data, a more appropriate target would be Victor's 
partials file format, if the data was sufficiently close in composition. 
I did make a basic conversion utility a long time ago to convert SDIF 
1TRC data to adsyn/hetro format, called "sdif2ad", which I think is 
still supplied with Csound; if that fits what Spear outputs, it ~might~ 
work.

thanks for the reply, richard.  i will have a closer look to the 
formats, and then get back.
