QUESTION FOR Applescript / Automator killers

Question

Hi guys,
Can someone tell me a way to select folder(s) by the type of files of their content ?
and then pass them as variable to proceed a search only in those folders ?
For example :  get every folders containing .wav files ---> = Variable
Search files named "xxx.app" in all the folders of Variable...
Automator or applescript are welcome .
Thanx in advance.
Best from paris (sorry for my english)
