I am trying to implement a diy beat tracker in max. What I'd like to do is keep a running list of the last, say 1024, samples received from a signal source in some mechanism (buffer, list?), then window it, then sum the 1024 samples together. Thus it gives me a smooth envelope signal -- something like E(n) = sum_(from i=n-1023 to i=n) (x(i)*w(i)) where w is a 1024-point window function. I was trying to use something like zl stream but that doesn't work on an audio signal.
