This plugin contains two nodes that allows you to analyse data over time.
I use both a lot to in FFT Analysis, to perform custom beat detection, but I'm sure there's other uses as well :)
This node allows you to check is a value has crossed a threshold compared to the value from the previous frame.
You can specify if you want to detect the threshold cross with the value increasing and/or decreasing.
This node allows you to detect when a value has been increasing and/or decreasing) for at least n frames (configurable individually for each direction), then it does output "true" and the value as soon as it goes in the opposite direction.
There is one help file for each plugin in the zip.
Source code in svn soon.
