It certainly is and I have no idea how that happened :-D. but it has no effect whatsoever. just delete the connection.

In that case just use [cmavg~] or [maverage~] with [snapshot~]. If you just want the sum of a signal vector, there are some objects in zexy that will do the job, like [avg~] or [pack~]+[sum] Gesendet: Dienstag, 08.

Well, a linear moving average filter is just something that sums a series of samples. If you don't want the average but rather the true sum, either multiply the output by the number of samples or take my abstraction and get rid of the [/~] object. Gesendet: Dienstag, 08.

The funny thing about linear moving average filters is, that although it can be implemented as a recursive filter (like in both our patches), it is still a FIR filter (and therefore it defeats the notion that recursive filters are always IIR filters). The impulse response is just a rectangular pulse and therefore finite. Gesendet: Dienstag, 08.
