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

what was the purpose of the output from the max object into rpole~ in your patch? that's a bug, right?
 
cheers

Or are you talking about a object that outputs the sum as a message? 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]

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.

cool guys, but i was asking for an average "sum" object :)
 
2015-12-08 9:19 GMT-02:00 Christof Ressi <christof.ressi@gmx.at>:Hey Matt,

there's no need for the feedback path (and therefore no [block~ 1] ;-))

Just use the following formula:

y[n] = (y[n-1] - x[n-k])/k

where k is the number of samples to be averaged (must be at least 1). see the patch I sent to Alex in my last mail.
it uses [rpole~ 1] for the y[n-1] part and [z~ k] for the x[n-k] part (you can replace the latter one with a [delwrite~] [delread~] pair to make it purely vanilla).

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.

Something like this? Almost completely untestsed. :D
