Does anybody have a suitable algorithm

Maybe this will give you some ideas :

Hmm,

implementing a FIR-filter is not difficult. Use this to calculate your data.

y(n) = sigma( a(n)*x(n-k) ) ; n = 0...m where m is the number of coef-1

( How can I get a math-symbol like sigma into a thread ??? )

If you want a reday-to-use-lib go and get the free (!) Signal-Processing-Lib from Intel.

So far ... Mario///
