FFTexternals 0.2 (by Nathan Wolek)/, "a small collection of externals 

used for various spectral processing. Includes objects for computing 

amplitude in decibels and a few complex math functions"/, are now 

available for Windows XP. It has been a while since these are ready but 

i was waiting for Nathan to confirm they behave as expected. It seems 

so. There's no link yet on Nathan's site but you can download them here,
