I am trying to detect the number of zero crossings at an interval of 10ms. The signal that i am using is just a randomly between two frequencies (1000hz and 2000hz) varying square wave. I basically want to detect when is the signal in 1000hz and when 2000hz state. Basically when there are 10 cycles in 10ms and when 20.

At the moment I am not counting zero crossings precisely, just using the example from the help file of [zerox~] which detects stable and transient. But it seems to be too slow.

DO you guys have any ideas how it could be done better?

here is mu patch with some explanations. I hope i am being clear with my idea.

Alright I found this solution, i think it will do it for me.

Actually I am still looking for the answer to my previous question. Here i made a version where I believe it should be good enough, because the counting of the zero crossings happens at a signal rate, and the number of them seems to be correct, it just seems too slow...

What do you want to do with the data stored in coll?

Maybe something like this..

if you are looking at the number~ boxes to indicate to you if the patch is doing what you want, you need to change it's update rate from 100ms to a shorter time period. use getinfo to do this. but more to the point you should be able to use zerox~ to simplify your patch greatly-- make sure your vector size is small enough to accommodate your required temporal resolution
