Hi DSP GURUS,
	I am working on a scheme to detect moisture content in corn using the
principle of ACOUSTIC PRESSURE.
	My question is , i would like to have some idea by which i can establish wether my assumptions are right. 
	It was stated by a proff. that depending on moisture content on corn seeds there is a variation in intensity of sound. He observed that the intensity of sound incresed around the 16kHz range. We planned to look out if we can find any frequency shift in t
he whole audio frequency spectrum.
	As for now i am acquiring the information of time domain data on a port-
-able data acquisistion system sampling at the rate of 76.8KHz. Conducting a Power Spectral Analysis on the data. From the results on three different samples itis observed that there is variation in the frequency spectrum. Can any of you 
suggest a scheme by which i can look at a narrow band and the best way to analyse my data. Is there any ready made routines for correlating data .
	One more question is on implemntation of Weiner filter (Algorithm or code). I would highly appreciate for some replies.
My e- mail add. is

	Thanx for the help in anticipataion of some assistance.
