HOW TO batch pitch recog/rename a bunch of wavs?

[wakax]

is there any good working tool under win (or osx) that does this?
- it scans a batch of wav files and detects their (fundamental/aprox) pitch
- it renames the wavs with the pitch found (for example the sound wav 3565.wav now it's 3565_C4.wav)

why do I need this?
kontakt (from my knowledge, doesnt have pitch recog and map according to pitch found)
and I want to do smth like this:

so if i have the wavs named with notes, kontakt will automap em just fine...

any help/ideas/links?
thanks!

ok - on my searchings I've found this lib
http://aubio.org/ multiplatform and commandline
and has "aubiopitch" inside that detects the pitch (has many methods for that and treshold).
now ... it just needs a GUI ...

I also found (and runs OK) a Python script that rename files to note names here:
(aubiopitch returns frequences)

problem is, this script is not so complexe and it returns only note name, not the octave.
